Description

Technical Field

[0001] This utility model relates to the field of speed reducer assembly technology, specifically a pneumatic clamping mechanism for equipment. Background Technology

[0002] A speed reducer is a component that reduces rotational speed and amplifies torque during automotive transmission. In other words, it's a mechanism used to reduce rotational speed and amplify torque when a car generates rotational driving force through an engine or motor. Speed ​​reducers require secure clamping during assembly and measurement, meaning there can be no movement, especially during measurements where precision is extremely high. This necessitates a very strong clamping force. Furthermore, speed reducers have complex structures, operate in confined spaces, and come in various types. Actual assembly and measurement require achieving high clamping force within a small space, while also ensuring flexibility and ease of replacement. Currently, speed reducer production processes all require secure clamping. Traditional clamping methods involve large-diameter air cylinders or small-volume hydraulic cylinders. However, large-diameter air cylinders are bulky and unsuitable for small spaces, while small-volume hydraulic cylinders present challenges in terms of flexibility and changeover. Hydraulic systems also have high changeover requirements and cannot meet the demands of small size, high clamping force, and high flexibility. Utility Model Content

[0003] The present invention aims to provide a pneumatic clamping mechanism for equipment, which can effectively clamp and fix a speed reducer.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] A pneumatic clamping mechanism for a device, comprising:

[0006] Mounting base, the top of which is fixedly connected to a clamping cylinder, and the output end of the clamping cylinder is provided through the mounting base. The output end of the clamping cylinder is fixedly connected to a bearing mounting block, and a loading bearing is mounted on the bearing mounting block.

[0007] A pressure block is fixedly connected to one side of the mounting base. The side wall of the pressure block is in close contact with the loading bearing. A clamping jaw is rotatably connected to the side of the mounting base away from the pressure block. A connecting rod is rotatably connected to the bottom end of the clamping jaw. The other end of the connecting rod is rotatably connected to the loading bearing, and the side wall of the loading bearing is in close contact with the surface of the clamping jaw.

[0008] Based on the above technical solution, its operating principle and the resulting technical effects are as follows:

[0009] When needed, the clamping cylinder is activated to extend or retract, which moves the bearing mounting block accordingly, thereby causing the loading bearing to extend or retract. When the loading bearing extends, pressure is applied to the surface where the loading bearing and the gripper are in contact, causing the gripper to rotate around pin one. After rotation, the gripper presses against the surface of the target workpiece, clamping it. When the clamping cylinder retracts, the loading bearing retracts, which drives the connecting rod to retract via pin two. The connecting rod, through pin three, drives the gripper to retract and release the target workpiece. The clamping mechanism of this application is small in size and has a large clamping force, which is greater than that of a pneumatic clamping device of the same size and close to that of a hydraulic clamping mechanism. It can achieve a large clamping force to clamp the target workpiece in confined spaces. At the same time, compared with a hydraulic clamping mechanism of the same size, this clamping mechanism has the advantage of flexible changeover, which can achieve automatic changeover during the production process, greatly improving the flexibility of the equipment mechanism.

[0010] In a preferred embodiment, the present invention can be further configured such that mounting plates are fixedly connected to both sides of the mounting base.

[0011] In a preferred embodiment, the present invention can be further configured such that: the bottom end of the mounting base is set as an opening, and a through groove for the deflection of the gripper is provided on one side of the mounting base, the through groove communicating with the opening.

[0012] In a preferred embodiment, the present invention can be further configured such that the gripper is bent as a whole, and the gripper is rotatably connected to the inner wall of the mounting base by a pin.

[0013] In a preferred embodiment, the present invention can be further configured such that: a second pin is fixed on the side wall of the bearing mounting block, and the load bearing includes an inner ring and an outer ring, the inner ring is fixed on the second pin, and the outer ring is in close contact with the surfaces of the pressure block and the clamping claw respectively.

[0014] In a preferred embodiment, the present invention can be further configured such that: a pin three is fixedly connected to the bottom side wall of the gripper; one end of the connecting rod is rotatably connected to the gripper via the pin three; the other end is rotatably connected to the pin two; and is rotatably connected to the loading bearing via the pin two.

[0015] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0016] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0017] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0018] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0019] A movable connection refers to a connection in which parts or components are fixed but have relative motion.

[0020] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0021] This invention utilizes the coordinated structure of grippers, loading bearings, and clamping cylinders to effectively clamp and fix the reducer. The clamping mechanism is compact yet possesses a large clamping force, exceeding that of a pneumatic clamping mechanism of the same size and approaching that of a hydraulic clamping mechanism. This allows for high-force clamping of the target workpiece even in confined spaces, making it more suitable for the actual application scenarios of reducers. Furthermore, compared to a hydraulic clamping mechanism of the same size, this invention offers the advantage of flexible changeover, enabling automatic changeover during production. This significantly improves the flexibility of the equipment mechanism, meeting the requirements of small size, high clamping force, and highly flexible changeover. Attached Figure Description

[0029] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0030] Based on the concept of this application, combined with Figures 1 to 5 This document describes an embodiment of a pneumatic clamping mechanism for assembling and clamping a speed reducer. Specifically, the pneumatic clamping mechanism is constructed as an integral structure, comprising three components: a mounting base 2, a clamping block, and a clamping jaw 9. Through the coordinated operation of the clamping jaw 9, the loading bearing 10, and the clamping cylinder 11, the speed reducer can be effectively clamped and fixed. Furthermore, the clamping mechanism is small in size but possesses a large clamping force, exceeding that of a pneumatic clamping mechanism of the same volume and approaching that of a hydraulic clamping mechanism. This allows for high-force clamping of the target workpiece even in confined spaces, making it more suitable for practical applications involving speed reducers.

[0031] Combination Figures 1-5 As shown, the present invention provides a pneumatic clamping mechanism for equipment, comprising:

[0032] Mounting base 2, the top of mounting base 2 is fixedly connected to a clamping cylinder 11, and the output end of the clamping cylinder 11 is set through the mounting base 2. The output end of the clamping cylinder 11 is fixedly connected to a bearing mounting block 4, and a loading bearing 10 is installed on the bearing mounting block 4.

[0033] The pressure block 3 is fixedly connected to one side of the mounting base 2. The side wall of the pressure block 3 is in close contact with the loading bearing 10. The side of the mounting base 2 away from the pressure block 3 is rotatably connected to the gripper 9. The bottom end of the gripper 9 is rotatably connected to the connecting rod 8. The other end of the connecting rod 8 is rotatably connected to the loading bearing 10, and the side wall of the loading bearing 10 is in close contact with the surface of the gripper 9.

[0034] Regarding the technical solution of this embodiment, mounting plates 1 are fixedly connected to both sides of the mounting base 2. The number of mounting plates 1 is set to two, and mounting holes are opened on each mounting plate 1. The device can be conveniently installed on the relevant equipment base using the mounting bracket, and can cooperate with the base to achieve clamping and fixing of the target workpiece.

[0035] Regarding the technical solution of this embodiment, the bottom end of the mounting base 2 is set as an opening, and a through groove for the deflection of the gripper 9 is provided on one side of the mounting base 2. The through groove is connected to the opening. The opening facilitates the extension and retraction of the load bearing 10 and avoids causing the opening, while the through groove facilitates the deflection and movement of the gripper 9 to achieve the clamping of the target workpiece.

[0036] Regarding the technical solution of this embodiment, the gripper 9 is configured as a bent shape. The gripper 9 is rotatably connected to the inner wall of the mounting base 2 via a pin 5. The top of the end of the gripper 9 away from the connecting rod 8 is configured as a flat surface, and the bottom is configured as a slope.

[0037] Regarding the technical solution of this embodiment, a second pin 6 is fixed on the side wall of the bearing mounting block 4. The loading bearing 10 includes an inner ring and an outer ring. The inner ring is fixed on the second pin 6, and the outer ring is in close contact with the surfaces of the pressure block 3 and the gripper 9. By using the loading bearing 10, a force can be applied to deflect the gripper 9.

[0038] Regarding the technical solution of this embodiment, a pin 3 7 is fixedly connected to the bottom side wall of the gripper 9. One end of the connecting rod 8 is rotatably connected to the gripper 9 via the pin 3 7, and the other end is rotatably connected to the pin 2 6. The connecting rod 8 is rotatably connected to the loading bearing 10 via the pin 2 6. When the clamping cylinder 11 is activated, it extends or retracts, which can drive the bearing mounting block 4 to move accordingly, thereby causing the loading bearing 10 to extend or retract. When the loading bearing 10 extends, pressure is applied to the surface of the loading bearing 10 that is in close contact with the gripper 9, causing the gripper 9 to rotate around the pin 1 5. After the gripper 9 rotates, it is pressed against the surface of the target workpiece, clamping the target workpiece. When the clamping cylinder 11 retracts, the loading bearing 10 retracts, and the connecting rod 8 is driven to retract via the pin 2 6. The connecting rod 8 drives the gripper 9 to retract via the pin 3 7, releasing the target workpiece.

[0039] It should be noted that the loading bearing 10 can rotate along the surfaces of the pressure block 3 and the jaw 9 during movement, thereby reducing the frictional force generated by the movement.

[0040] Furthermore, by using the force amplification structure of the bearing 10, pressure block 3, and gripper 9, the output force of the clamping cylinder 11 is amplified to clamp the target workpiece. The specific principle is as follows: Figure 5 As shown, F1 is the output force of the clamping cylinder 11 on the loading bearing 10, F2 is the reverse force of the gripper 9 on the loading bearing 10, and F3 is the supporting force of the pressure block 3 on the loading bearing 10. The three forces F1 / F2 / F3 are balanced and form a horizontal angle of 8°. F2=F1÷si n8.

[0041] Specifically, when needed, the clamping cylinder 11 is activated to extend or retract, which moves the bearing mounting block 4 accordingly, thereby causing the loading bearing 10 to extend or retract. When the loading bearing 10 extends, pressure is applied to the surface of the loading bearing 10 that is in close contact with the gripper 9, causing the gripper 9 to rotate around the first pin 5. After rotating, the gripper 9 presses against the surface of the target workpiece, clamping the target workpiece. When the clamping cylinder 11 retracts, the loading bearing 10 retracts, which drives the connecting rod 8 to retract via the second pin 6. The connecting rod 8 then drives the gripper 9 to retract via the third pin 7, releasing the target workpiece. The clamping mechanism of this application is small in size and has a large clamping force, which is greater than that of a pneumatic clamping device of the same size and close to that of a hydraulic clamping mechanism. It can achieve a large clamping force to clamp the target workpiece in a confined space. At the same time, compared with a hydraulic clamping mechanism of the same size, this clamping mechanism has the advantage of flexible changeover, which can achieve automatic changeover during the production process, greatly improving the flexibility of the equipment mechanism.

[0042] The pneumatic clamping mechanism for equipment provided by this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0044] Mounting base 2, the top of mounting base 2 is fixedly connected to a clamping cylinder 11, and the output end of the clamping cylinder 11 is set through the mounting base 2. The output end of the clamping cylinder 11 is fixedly connected to a bearing mounting block 4, and a loading bearing 10 is installed on the bearing mounting block 4.

[0045] The pressure block 3 is fixedly connected to one side of the mounting base 2. The side wall of the pressure block 3 is in close contact with the loading bearing 10. The side of the mounting base 2 away from the pressure block 3 is rotatably connected to the gripper 9. The bottom end of the gripper 9 is rotatably connected to the connecting rod 8. The other end of the connecting rod 8 is rotatably connected to the loading bearing 10, and the side wall of the loading bearing 10 is in close contact with the surface of the gripper 9.

[0046] The working principle and usage process of this utility model are as follows: When needed, the clamping cylinder 11 is activated to extend or retract, which moves the bearing mounting block 4 accordingly, thereby causing the loading bearing 10 to extend or retract. When the loading bearing 10 extends, pressure is applied to the surface of the loading bearing 10 and the gripper 9, causing the gripper 9 to rotate around the first pin 5. After rotation, the gripper 9 presses against the surface of the target workpiece, clamping the target workpiece. When the clamping cylinder 11 retracts, the loading bearing 10 retracts, and the connecting rod 8 retracts through the second pin 6. The connecting rod 8, through the third pin 7, causes the gripper 9 to retract and release the target workpiece. The clamping mechanism of this application is small in size and has a large clamping force, which is greater than that of a pneumatic clamping device of the same size and close to that of a hydraulic clamping mechanism. It can achieve a large clamping force to clamp the target workpiece in a confined space. At the same time, compared with a hydraulic clamping mechanism of the same size, this clamping mechanism has the advantage of flexible changeover, which can achieve automatic changeover during the production process, greatly improving the flexibility of the equipment mechanism.
