Description

Technical Field

[0001] This application relates to the field of shock absorber processing technology, and more specifically, to a comprehensive reaction force testing machine. Background Technology

[0002] The manufacturing process of shock absorbers or dampers typically involves two key steps: first, testing the force characteristics of the product to ensure its performance meets design requirements; and second, pressing together components such as dust covers. Currently, the industry generally uses independent equipment to complete these steps separately. That is, mechanical performance testing is first performed on a force testing device, and then the workpiece is transferred to another pressing device to complete the assembly of the dust cover.

[0003] This traditional split-process operation method has many drawbacks. First, the workpiece needs to be moved and positioned multiple times between two machines, which not only reduces production efficiency and increases the labor intensity of operators, but also introduces errors during repeated positioning, affecting the final assembly accuracy. Second, the separation of force value detection and pressing processes makes it difficult to achieve real-time closed-loop control of quality data. If a product is found to be defective during the force value detection stage, it may still be transferred to the subsequent pressing process, resulting in a waste of production resources and failing to fundamentally prevent the outflow of defective products.

[0004] Therefore, the industry urgently needs a processing equipment that can highly integrate force value detection and dust cover pressing functions. Utility Model Content

[0005] The purpose of this application is to provide a comprehensive reaction force testing machine that can continuously complete the force value testing of dampers and the pressing of dust covers at the same station, thereby improving the above-mentioned problems.

[0006] This application is achieved through the following technical solution: This application provides a comprehensive reaction force testing machine, which includes a first drive mechanism and a second drive mechanism arranged opposite to each other, and a pressing fixture disposed between the two drive mechanisms. The output end of the first drive mechanism is provided with a pressure head with a sensor, and the output end of the second drive mechanism is provided with a positioning seat. The pressing fixture is used to fit the front fork of the workpiece. The workpiece is clamped between the pressure head and the positioning seat, and its bottom cylinder is engaged with the positioning seat. The front fork contacts the pressure head and is covered with a dust cover. The first drive mechanism drives the pressure head to press against the workpiece, and the sensor detects the force value. The second drive mechanism drives the positioning seat to push the bottom cylinder and the dust cover on it to move towards the pressing fixture, and the dust cover is pressed by pressing against the pressing fixture.

[0007] In the technical solution of this application embodiment, by integrating force value detection and dust cover pressing functions into one device, the handling and repeated positioning and clamping of workpieces between two separate devices for detection and pressing are avoided, enabling seamless connection between the two processes and significantly shortening the processing time. All operations are completed in a single workpiece clamping, eliminating the cumulative errors caused by multiple positioning and ensuring the final assembly accuracy of the dust cover pressing. Force value detection, as a necessary step before pressing, provides data that can be directly used to determine whether the workpiece is qualified. If the detection fails, the pressing process can be stopped or skipped immediately, preventing ineffective assembly of defective products, saving resources, and preventing defective products from leaving the site.

[0008] In some embodiments, the system further includes a memory and a control module. The memory stores a rated force range for the workpiece. The control module is configured to: compare the actual force value detected by the sensor with the rated force range; if the actual force value meets the rated range, activate the second drive mechanism to perform dust cover pressing; if the actual force value does not meet the rated range, stop the second drive mechanism and generate a workpiece recycling prompt.

[0009] In the technical solution of this application embodiment, by introducing a memory and control module, the force value detection result is upgraded from manual interpretation to automatic system decision-making, eliminating the risk of human error and automating and intelligentizing the entire process. Hardware interlocking (stopping the second drive mechanism) prevents defective products from flowing into the pressing process, avoiding subsequent waste of materials and time. Automated workpiece recovery prompts immediately guide operators to handle anomalies, shortening anomaly response time and providing timely and accurate data for production quality management.

[0010] In some embodiments, the second drive mechanism includes a lifting drive assembly and a rotating drive assembly; the lifting drive assembly is used to drive the positioning seat to lift and lower to complete the pressing of the dust cover; the rotating drive assembly is used to drive the positioning seat to rotate around the workpiece height direction to adjust the pressing angle between the bottom cylinder and the dust cover.

[0011] In the technical solution of this application embodiment, a rotation and re-pressing process is added after the initial press-fitting. Through multi-angle segmented press-fitting, the dust cover is evenly embedded into the bottom cylinder, eliminating edge gaps and improving product sealing and appearance quality. For irregularly shaped dust covers or cases of uneven force, the re-press-fitting after angle adjustment compensates for the deficiencies of a single press-fitting, ensuring assembly consistency. The multi-angle press-fitting process reduces rework rates caused by improper assembly, improving production efficiency and product qualification rate.

[0012] In some embodiments, when the rotary drive assembly drives the positioning seat to rotate, there is a gap between the dust cover and the pressing fixture.

[0013] In the technical solution of this application embodiment, a gap is ensured between the dust cover and the pressing fixture during rotation. This gap prevents frictional resistance or interference between the dust cover and the pressing fixture during rotation, making angle adjustment more flexible and accurate. Non-contact rotation adjustment prevents scratches or wear on the outer surface of the dust cover and the working surface of the pressing fixture, protecting the product and the fixture.

[0014] In some embodiments, the positioning seat is provided with a positioning protrusion; the positioning protrusion engages with a groove on the bottom of the workpiece to achieve workpiece positioning.

[0015] In the technical solution of this application embodiment, the engaging structure of the protrusion and the groove provides a clear installation position for the workpiece, simplifies the clamping operation, and improves the positioning accuracy and efficiency.

[0016] In some embodiments, the positioning seat is further provided with an orientation component for abutting against the side wall of the bottom cylinder to limit the rotation of the bottom cylinder relative to the positioning seat.

[0017] In the technical solution of this application embodiment, an orientation component is added to the positioning seat. Through lateral clamping force, the relative rotation between the bottom cylinder and the positioning seat is restricted during processing. Lateral clamping improves the overall rigidity of the workpiece and the positioning seat, which helps to ensure the accuracy of force value detection and the stability of the pressing process.

[0018] In some embodiments, the orientation assembly includes an orientation member in contact with the bottom cylinder and a drive rod; the drive rod is hinged to the positioning seat; the drive rod is rotatable under the push of the rotation drive assembly, causing the orientation member to press against the bottom cylinder.

[0019] In the technical solution of this application embodiment, the initial contact between the directional component and the bottom cylinder sidewall without applying force ensures accurate workpiece positioning, while the subsequent tilting and clamping provides reliable anti-rotation capability. The gapless initial contact prevents workpiece wobbling during positioning, providing an accurate reference for subsequent processing. The transition from contact to clamping between the directional component and the bottom cylinder sidewall is smooth and continuous, avoiding the impact of impact on the workpiece position.

[0020] In some embodiments, the rotary drive assembly includes a drive member, a gear, and a rack; the gear is fixedly connected to a positioning seat; the drive member drives the rack to move so as to rotate the gear; the rack engages with a transmission rod, and the rack moves to push the transmission rod to rotate.

[0021] In the technical solution of this application embodiment, a rack is driven by a driving component, which simultaneously realizes the two functions of clamping and fixing the workpiece and rotating and adjusting the positioning seat. By utilizing the natural sequence of rack movement, the workpiece is clamped and fixed first, and then the angle is adjusted, ensuring the reliability of the process.

[0022] In some embodiments, the travel of the rack includes a pushing section and an engaging section; in the pushing section, the rack pushes the transmission rod to rotate so that the guide member presses against the bottom cylinder; in the engaging section, the rack engages with the gear to drive the gear to rotate.

[0023] In the technical solution of this application embodiment, by clearly dividing the movement stroke of the rack into a pushing segment and a meshing segment, the action sequence of clamping followed by rotation is achieved, ensuring the correct execution of the process logic from a mechanical structure perspective. Each stroke segment performs its specific function, avoiding functional interference and making power transmission more efficient and reliable. Clear functional segmentation reduces the possibility of misoperation and enhances the working stability of the entire system.

[0024] In some embodiments, the transmission rod includes a first section and a second section hinged to each other; one end of the first section is connected to a guide member, and the other end is provided with a spring plate; a rack overlaps with the second section, and the spring plate overlaps with the second section; when the rack pushes the second section, the second section drives the first section to rotate by pushing the spring plate, so that the guide member abuts against the bottom cylinder; when the pressure on the spring plate reaches the rated value, it undergoes elastic deformation, so that the second section can rotate relative to the first section about the hinge axis, so as to prevent the pressure of the guide member on the bottom cylinder from continuing to increase.

[0025] In the technical solution of this application embodiment, when the clamping force reaches the rated value, the elastic deformation of the spring automatically limits the pressure from continuing to increase, preventing damage to the workpiece and providing a reliable overload protection mechanism for the workpiece and the orientation assembly. Precise control of the clamping force is achieved through the mechanical properties of the spring, ensuring that each workpiece receives the same clamping effect. This mechanical overload protection requires no intervention from sensors or electronic control systems, has a simple structure, reliable response, and improves equipment safety.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0034] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0035] In this application, "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).

[0036] According to some embodiments of this application, optionally, such as Figures 1-2 As shown, this application provides a comprehensive reaction force testing machine, which includes a first drive mechanism 2 and a second drive mechanism 3 arranged opposite to each other, and a pressing fixture 4 disposed between the two drive mechanisms. The output end of the first drive mechanism 2 is provided with a pressure head 20 with a sensor, and the output end of the second drive mechanism 3 is provided with a positioning seat 30. The pressing fixture 4 is used to fit the front fork 10 of the workpiece 1. The workpiece 1 is clamped between the pressure head 20 and the positioning seat 30, and its bottom cylinder 11 is engaged with the positioning seat 30. The front fork 10 contacts the pressure head 20 and is covered with a dust cover. The first drive mechanism 2 drives the pressure head 20 to press against the workpiece 1, and the force value is detected by the sensor. The second drive mechanism 3 drives the positioning seat 30 to push the bottom cylinder 11 and the dust cover on it to move towards the pressing fixture 4, and the dust cover is pressed by pressing against the pressing fixture 4.

[0037] A shock absorber (also known as a damper) is a mechanical component used to suppress vibrations and slow down movement. It is widely used in automobiles, home appliances, and machinery. When equipment or components (such as car wheels or washing machine drums) vibrate or move rapidly, the shock absorber generates resistance through its internal structure (such as oil or springs), reducing vibration, smoothing movement, and preventing damage or noise from severe vibrations. The mechanical properties of the shock absorber directly determine its performance; therefore, force testing is an indispensable part of shock absorber production.

[0038] Dust covers are protective accessories on shock absorbers, usually made of rubber or plastic.

[0039] Press fitting is a high-precision assembly process that refers to the process of pressing two or more parts together by applying stable pressure with equipment.

[0040] In practical application, the operator clamps workpiece 1 (such as a shock absorber) into the equipment. Specifically, the bottom cylinder 11 of workpiece 1 is engaged with the positioning seat 30 at the output end of the second drive mechanism 3, while the front fork 10 of workpiece 1 contacts the pressure head 20 at the output end of the first drive mechanism 2, and a dust cover is pre-attached to the front fork 10. Simultaneously, the front fork 10 of workpiece 1 is partially fitted onto the pressing fixture 4 located between the two drive mechanisms. After clamping, the equipment is started. The first drive mechanism 2 drives the pressure head 20 to press against the front fork 10 of workpiece 1, and the force value is detected by the sensor on the pressure head 20 to obtain the mechanical performance data of workpiece 1. Subsequently, the second drive mechanism 3 drives the positioning seat 30 to push the bottom cylinder 11 of workpiece 1 and its dust cover towards the pressing fixture 4 until the dust cover is pressed tightly against the pressing fixture 4, completing the pressing of the dust cover. Throughout the entire process, workpiece 1 completes two consecutive processes—force value detection and dust cover pressing—after one clamping operation.

[0041] This application integrates force measurement and dust cover pressing functions into a single device, avoiding the need for handling and repeated positioning and clamping of workpiece 1 between two separate devices. This seamlessly connects the two processes and significantly shortens processing time. Workpiece 1 completes all operations in a single clamping, eliminating cumulative errors caused by multiple positioning steps and ensuring the final assembly accuracy of the dust cover pressing. Force measurement, as a necessary step before pressing, provides data that can be directly used to determine whether workpiece 1 is qualified. If the measurement fails, the pressing process can be stopped or skipped immediately, preventing ineffective assembly of defective products, saving resources, and preventing defective products from leaving the site.

[0042] In the specific implementation process, before clamping the workpiece 1, the pressure head 20 and the positioning seat 30 can be raised and lowered by the first driving mechanism 2 and the second driving mechanism 3, so that the interval between the pressure head 20, the pressing fixture 4 and the positioning seat 30 can be adapted to the size of the workpiece 1 to be processed, thereby enabling the equipment provided in this application to adapt to the processing needs of workpieces 1 of various sizes.

[0043] According to some embodiments of this application, optionally, a memory and a control module are also included. The memory pre-stores the rated force range of the workpiece 1. The control module is configured to: compare the actual force value detected by the sensor with the rated force range; if the actual force value meets the rated range, start the second drive mechanism 3 to perform dust cover pressing; if the actual force value does not meet the rated range, stop the second drive mechanism 3 and generate a workpiece 1 recycling prompt.

[0044] In practical applications, after the operator clamps workpiece 1, they start the equipment. The first drive mechanism 2 drives the pressure head 20 with a sensor to perform force value detection. At this time, the control module reads the actual force value collected by the sensor in real time and automatically compares it with the rated force value range of workpiece 1 of this model stored in the memory. According to the comparison result, the control module executes the predetermined control logic: if the actual force value is within the rated force value range, the control module automatically sends a start command to the second drive mechanism 3, causing it to drive the positioning seat 30 to complete the pressing of the dust cover; if the actual force value exceeds (is greater than or less than) the rated force value range, the control module immediately stops the second drive mechanism 3, preventing it from moving, and at the same time generates and issues a workpiece 1 recycling prompt (for example, through an alarm indicator light or sound prompt on the operation interface), informing the operator to remove this defective product from the production line.

[0045] This application example upgrades the force value detection results from manual interpretation to automatic system decision-making by introducing a memory and control module, eliminating the risk of human error and automating and intelligentizing the entire process. Hardware interlocking (stopping the second drive mechanism 3) prevents defective products from flowing into the pressing process, avoiding subsequent waste of materials and time. The automated workpiece 1 recovery prompt immediately guides operators to handle anomalies, shortening response time and providing timely and accurate data for production quality management.

[0046] According to some embodiments of this application, optionally, such as Figures 2-3 As shown, the second drive mechanism 3 includes a lifting drive assembly 31 and a rotating drive assembly 32; the lifting drive assembly 31 is used to drive the positioning seat 30 to lift and lower to complete the pressing of the dust cover; the rotating drive assembly 32 is used to drive the positioning seat 30 to rotate around the height direction of the workpiece 1 to adjust the pressing angle between the bottom cylinder 11 and the dust cover.

[0047] In practical applications, the operator engages the bottom cylinder 11 of workpiece 1 onto the positioning seat 30. The lifting drive assembly 31 of the second drive mechanism 3 first drives the positioning seat 30 to rise and fall, completing the initial pressing of the dust cover. After the initial pressing, the operator can activate the rotation drive assembly 32 according to the actual assembly situation. This assembly drives the positioning seat 30 to rotate around the height of workpiece 1 by a specific angle, changing the pressing angle between the bottom cylinder 11 and the dust cover. Subsequently, the lifting drive assembly 31 drives the positioning seat 30 to rise and fall again, performing a second pressing of the same dust cover. This multi-angle segmented pressing process avoids the edge gap problem between the dust cover and the bottom cylinder 11 caused by a single pressing.

[0048] This embodiment adds a rotation and re-pressing process after the initial pressing. Through multi-angle segmented pressing, the dust cover is evenly embedded into the bottom cylinder 11, eliminating edge gaps and improving product sealing and appearance quality. For irregularly shaped dust covers or cases of uneven force, the re-pressing after angle adjustment compensates for the deficiencies of the single pressing, ensuring assembly consistency. The multi-angle pressing process reduces rework rates due to improper assembly, improving production efficiency and product qualification rate.

[0049] According to some embodiments of this application, optionally, when the rotary drive assembly 32 drives the positioning seat 30 to rotate, there is a gap between the dust cover and the pressing fixture 4.

[0050] In practical applications, when the pressing angle needs to be adjusted, a certain gap is always maintained between the dust cover and the pressing fixture 4 during the rotation of the positioning seat 30 around the height of the workpiece 1 driven by the rotary drive assembly 32. This gap ensures that the dust cover is in a free state during the rotational angle adjustment and does not come into contact with or interfere with the pressing fixture 4. After the rotary drive assembly 32 completes the angle adjustment, the lifting drive assembly 31 drives the positioning seat 30 to rise, eliminating the gap and making the dust cover press against the pressing fixture 4, thus completing the pressing operation.

[0051] This embodiment ensures that a gap exists between the dust cover and the pressing fixture 4 during rotation. This gap prevents frictional resistance or interference between the dust cover and the pressing fixture 4 during rotation, making angle adjustment more flexible and accurate. Non-contact rotation adjustment prevents scratches or wear on the outer surface of the dust cover and the working surface of the pressing fixture 4, protecting the product and the fixture.

[0052] According to some embodiments of this application, optionally, such as Figure 2 As shown, the positioning seat 30 is provided with a positioning protrusion 300; the positioning protrusion 300 engages with the groove at the bottom of the workpiece 1 to achieve the positioning of the workpiece 1.

[0053] In practical applications, when the operator clamps the workpiece 1 onto the positioning seat 30, the operator aligns and engages the groove at the bottom of the workpiece 1's bottom cylinder 11 with the positioning protrusion 300 on the positioning seat 30. This engagement action allows the workpiece 1 to achieve precise initial positioning on the positioning seat 30.

[0054] The interlocking structure of the protrusions and grooves provides a clear installation position for workpiece 1, simplifies the clamping operation, and improves positioning accuracy and efficiency.

[0055] According to some embodiments of this application, optionally, such as Figures 2-8 As shown, the positioning seat 30 is also provided with an orientation component 5, which is used to press against the side wall of the bottom cylinder 11 and restrict the rotation of the bottom cylinder 11 relative to the positioning seat 30.

[0056] In practical applications, when the operator clamps the bottom cylinder 11 of workpiece 1 onto the positioning seat 30, the groove at the bottom of the bottom cylinder 11 engages with the positioning protrusion 300 of the positioning seat 30, completing the initial positioning. Subsequently, the orientation component 5 provided on the positioning seat 30 is activated, pressing against the side wall of the bottom cylinder 11 from the side. When the rotation drive component 32 drives the positioning seat 30 to rotate, the relative rotational movement between the bottom cylinder 11 and the positioning seat 30 is limited by the pressing action of the orientation component 5 against the side wall of the bottom cylinder 11, ensuring the accuracy of angle adjustment.

[0057] In this embodiment, an orientation component 5 is added to the positioning seat 30. Through lateral clamping force, the relative rotation between the bottom cylinder 11 and the positioning seat 30 is restricted during processing. Lateral clamping improves the overall rigidity of the workpiece 1 and the positioning seat 30, which helps to ensure the accuracy of force value detection and the stability of the pressing process.

[0058] According to some embodiments of this application, optionally, such as Figures 4-8 As shown, the orientation assembly 5 includes an orientation member 50 that contacts the bottom cylinder 11 and a transmission rod 51; the transmission rod 51 is hinged to the positioning seat 30; the transmission rod 51 can rotate under the push of the rotation drive assembly 32, driving the orientation member 50 to press against the bottom cylinder 11.

[0059] In practical applications, before driving the positioning seat 30 to rotate, the rotary drive assembly 32 first pushes the transmission rod 51. Since the transmission rod 51 is hinged to the positioning seat 30, the pushing force causes it to rotate. The rotation of the transmission rod 51 drives the directional member 50 connected to it to move towards the side wall of the bottom cylinder 11, eventually pressing tightly against the side wall of the bottom cylinder 11, thus completing the fixation of the bottom cylinder 11. Subsequently, the rotary drive assembly 32 begins to drive the entire positioning seat 30 (which is now fixed to the bottom cylinder 11 by the directional member 50) to rotate, adjusting the pressing angle.

[0060] In practical applications, in the initial state, the directional component 50 maintains contact with the mating surface of the bottom cylinder 11 sidewall but does not apply clamping force, achieving gapless initial positioning. When it is necessary to lock the workpiece 1, the rotary drive assembly 32 pushes the transmission rod 51, causing it to rotate around the hinge point. The rotation of the transmission rod 51 pushes the directional component 50, causing a change in the relative position between its mating surface and the bottom cylinder 11 sidewall, resulting in a slight tilt. This tilt causes the mating surface of the directional component 50 to change from the initial mating state to applying clamping force to the bottom cylinder 11 sidewall, thereby achieving reliable clamping and fixing.

[0061] The initial contact between the directional component 50 and the side wall of the bottom cylinder 11, without applying force, ensures accurate positioning of the workpiece 1, while the subsequent tilting and clamping provides reliable anti-rotation capability. The gapless initial contact prevents workpiece 1 from wobbling during positioning, providing an accurate reference for subsequent processing. The smooth and continuous transition from contact to clamping between the directional component 50 and the side wall of the bottom cylinder 11 avoids the impact on the position of workpiece 1.

[0062] According to some embodiments of this application, optionally, such as Figures 4-6 As shown, the rotary drive assembly 32 includes a drive member 320, a gear 322, and a rack 321; the gear 322 is fixedly connected to the positioning seat 30; the drive member 320 drives the rack 321 to move so as to drive the gear 322 to rotate; the rack 321 is engaged with the transmission rod 51, and when the rack 321 moves, it pushes the transmission rod 51 to rotate.

[0063] In practical applications, when the pressing angle needs to be adjusted, the drive component 320 is activated, driving the rack 321 to move. The movement of the rack 321 has two simultaneous effects: firstly, the rack 321 meshes with the gear 322, causing the gear 322, which is fixedly connected to the positioning seat 30, to rotate, thereby driving the positioning seat 30 to rotate; secondly, the rack 321 engages with the transmission rod 51, pushing the transmission rod 51 to rotate around its hinge point during movement. The rotation of the transmission rod 51 then causes the guide component 50 to tilt, changing the contact surface of the guide component 50 from its initial contact state to applying a pressing force to the side wall of the bottom cylinder 11, thus fixing the workpiece 1. Afterward, the rack 321 continues to move, specifically to drive the gear 322 to rotate the positioning seat 30, adjusting the pressing angle.

[0064] In this embodiment, a drive unit 320 drives a rack 321, which simultaneously realizes two functions: clamping and fixing the workpiece 1 and rotating and adjusting the positioning seat 30. By utilizing the natural sequence of movement of the rack 321, the workpiece 1 is clamped and fixed first, and then the angle is adjusted, ensuring the reliability of the process.

[0065] According to some embodiments of this application, optionally, such as Figures 6-8As shown, the travel of the rack 321 includes a pushing section and a meshing section; in the pushing section, the rack 321 pushes the transmission rod 51 to rotate so that the guide member 50 presses against the bottom cylinder 11; in the meshing section, the rack 321 meshes with the gear 322 to drive the gear 322 to rotate.

[0066] In practical applications, when the drive unit 320 is activated, the rack 321 begins to move. In the initial pushing phase, the rack 321 engages with the transmission rod 51 and pushes it to rotate. At this time, the rack 321 has not yet meshed with the gear 322, or although it is meshed, no effective transmission is generated. The rotation of the transmission rod 51 drives the guide member 50 to press against the side wall of the bottom cylinder 11, completing the fixing of the workpiece 1. Subsequently, the rack 321 enters the meshing phase. At this time, the transmission rod 51 has reached the predetermined position, and the rack 321 continues to move and fully meshes with the gear 322, driving the gear 322 to rotate, thereby driving the positioning seat 30 and the fixed workpiece 1 to rotate, adjusting the pressing angle.

[0067] This embodiment clearly divides the travel of the rack 321 into a pushing segment and a meshing segment, achieving a clamping-then-rotating action sequence, thus ensuring the correct execution of the process logic from a mechanical structure perspective. Each travel segment performs its specific function, avoiding functional interference and making power transmission more efficient and reliable. Clear functional segmentation reduces the possibility of misoperation and enhances the overall system stability.

[0068] According to some embodiments of this application, optionally, such as Figures 4-8 As shown, the transmission rod 51 includes a first section 510 and a second section 511 that are hinged to each other; one end of the first section 510 is connected to the directional member 50, and the other end is provided with a spring piece 5100; the rack 321 overlaps with the second section 511, and the spring piece 5100 overlaps with the second section 511; when the rack 321 pushes the second section 511, the second section 511 drives the first section 510 to rotate by pushing the spring piece 5100, so that the directional member 50 presses against the bottom cylinder 11; when the pressure on the spring piece 5100 reaches the rated value, it undergoes elastic deformation, so that the second section 511 can rotate relative to the first section 510 around the hinge axis, so as to prevent the pressure of the directional member 50 on the bottom cylinder 11 from continuing to increase.

[0069] In practical applications, when rack 321 moves in the pushing section, it engages with the second section 511 of transmission rod 51 and pushes it to move. The second section 511 drives the first section 510 to rotate around the hinge point by pushing spring 5100, and the first section 510 drives the guide member 50 to press against the side wall of the bottom cylinder 11. As rack 321 continues to push, the pressure on spring 5100 gradually increases. When the pressure reaches the preset rated value, spring 5100 undergoes elastic deformation, allowing the second section 511 to rotate relative to the first section 510 around the hinge axis. At this time, even if rack 321 continues to move, the first section 510 will no longer continue to rotate, thereby preventing the pressure of guide member 50 on bottom cylinder 11 from continuing to increase.

[0070] When the clamping force reaches the rated value, the elastic deformation of the spring 5100 automatically limits the pressure from further increasing, preventing damage to workpiece 1 and providing a reliable overload protection mechanism for workpiece 1 and the orientation assembly 5. Precise control of the clamping force is achieved through the mechanical properties of the spring 5100, ensuring that each workpiece 1 receives the same clamping effect. This mechanical overload protection requires no sensor or electronic control system intervention, has a simple structure, reliable response, and improves equipment safety.

[0071] In the specific implementation process, a roller 5110 can also be set at the end of the second segment 511 near the rack 321. When the second segment 511 rotates relative to the first segment 510, the second segment 511 and the rack 321 change from overlapping to contacting each other through the roller 5110. This ensures that the clamping force transmitted by the rack 321 to the directional member 50 through the second segment 511 is always effective, while reducing the friction between the second segment 511 and the rack 321, thus preventing damage to both.

[0072] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
