Description

Technical Field

[0001] This invention relates to the field of cutting fixture technology, and in particular to a cutting fixture device for adjusting the detection distance of a sensor. Background Technology

[0002] In the manufacturing process of sensors, finished or semi-finished sensors typically need to be cut to remove excess material or adjust their dimensions. To ensure cutting accuracy, a cutting fixture is usually used to position and clamp the sensor, and then transport it to the inspection station to calibrate the cutting reference position. Existing cutting fixtures generally include a fixed support, a sliding worktable, and a clamping mechanism. After the sensor is fixed by the clamping mechanism, a drive mechanism moves it to the cutting or inspection station.

[0003] However, existing cutting fixture devices still have the following shortcomings in practical applications: Firstly, the clamping force cannot be adaptively adjusted, easily leading to positioning deviations or workpiece damage. Existing clamping mechanisms typically use cylinders or electric push rods to drive the clamping plate to fix the sensor. Once the clamping force is set, it cannot be automatically adjusted according to actual working conditions. When the sensor is pushed axially by the positioning component, if the clamping force is insufficient, the sensor is prone to axial movement or radial wobble, causing the positioning reference to shift and affecting cutting accuracy. If the clamping force is too large, it may damage the sensor shell or internal precision components. Especially in batch processing, the dimensional tolerances of different batches of sensors vary, and it is difficult to maintain a fixed clamping force for all workpieces, resulting in a high scrap rate.

[0004] Secondly, the lack of real-time sensing of the clamping status makes it impossible to determine whether the clamping degree is appropriate. With existing devices, during the contact between the sensor and the positioning component, operators cannot know whether the current clamping force is sufficient to resist the positioning resistance. They can only indirectly judge this after cutting by checking the results, resulting in a delayed response and an inability to eliminate the risk of loosening before processing, leading to unnecessary material waste and lost time.

[0005] Therefore, it is necessary to provide a cutting fixture device for adjusting the sensor detection distance to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a cutting fixture device for adjusting the sensor detection distance, so as to solve the defects of the prior art mentioned in the background art.

[0007] Based on the above ideas, the present invention provides the following technical solution: A cutting fixture device for adjusting the detection distance of a sensor includes a fixed bracket, a fixed plate fixedly connected to the outside of the fixed bracket, and further includes: The testing mechanism, located on top of the fixed plate, is used to test the sensing distance of the sensors to be processed. A sliding plate is slidably mounted on the top of a fixed bracket, and two fixed platforms are fixedly connected to the top of the sliding plate. The two fixed platforms have receiving slots inside, and the two fixed platforms can be alternately switched to the front side of the detection mechanism in the middle of the fixed plate. A positioning element is disposed inside the receiving groove and is used to abut against the end of the sensor to define the axial position of the sensor; A fixing cylinder is disposed inside a receiving groove, and a clamping assembly is disposed inside the fixing cylinder.

[0010] As a further embodiment of the present invention: the locking member includes a pressing plate, the clamping plate has a placement groove, the pressing plate is disposed inside the placement groove, and the pressing plate is set as an inclined surface near the fixed cylinder. Both ends of the pressing plate are fixedly connected to connecting plates, and a first spring is fixedly connected between the connecting plates and the clamping plate. A pushing frame is slidably connected to the outside of the clamping plate and contacts one side of the pressing plate. When the pushing frame moves, it pushes the pressing plate down to lock the sensor surface.

[0011] As a further embodiment of the present invention: the flexible traction mechanism includes a rotating rod, a support plate is fixedly connected to the outside of the clamping plate, the rotating rod passes through the support plate and is rotatably connected to the support plate, a fourth gear is fixedly connected to both ends of the rotating rod, the fourth gear meshes with the third gear, a take-up reel is fixedly connected to the outside of the rotating rod, a tensioning steel wire is wound and fixedly fixed to the outside of the take-up reel, and the tensioning steel wire is fixedly connected to the push frame.

[0012] As a further embodiment of the present invention: a ratchet is fixedly connected to the outside of the rotating rod, a fixed frame is fixedly connected to the outside of the clamping plate, a pawl is connected to the outside of the fixed frame by a torsion spring, the pawl limits the ratchet in one direction, and a fixed rod is fixedly connected to the inner wall of the fixed cylinder. When the clamping plate is reset and raised, the fixed rod contacts one end of the pawl, so that the pawl releases the limitation on the ratchet.

[0013] As a further embodiment of the present invention: an airbag is fixedly connected to the outside of the clamping plate, and air cylinders are fixedly connected to both sides of the clamping plate. The air cylinders and the airbags are fixedly connected through a connecting pipe. A push plate is slidably connected inside the air cylinder. A sliding rod is fixedly connected to the outside of the push plate. The sliding rod passes through one end of the air cylinder and is slidably connected to the air cylinder. The sliding rod is fixedly connected to the push frame. A second spring is sleeved on the outside of the sliding rod. The two ends of the second spring are fixedly connected to the push plate and the air cylinder, respectively.

[0014] As a further aspect of the present invention: the positioning element includes a contact plate, which is disposed inside the receiving groove, and a mounting bracket is fixedly connected to the outside of the fixing platform. A return spring is fixedly connected between the mounting bracket and the contact plate, and a contact rod is fixedly connected to the side of the contact plate near the mounting bracket.

[0015] As a further embodiment of the present invention: the driving mechanism includes a sliding block, the sliding block is fixedly connected to the outside of the fixed cylinder, a sliding groove is opened inside the fixed platform, a driving screw is rotatably connected inside the sliding groove, the driving screw passes through the sliding block and is connected to the sliding block through a ball nut, a side plate is connected to the outside of the fixed cylinder, the side plate is slidably engaged with the fixed platform, a driving gear is fixedly connected to one end of the driving screw, a rack is fixedly connected to the top of the fixed bracket, and the rack is meshed with the driving gear.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The flexible traction mechanism is driven by the friction between the contact element and the sensor surface. During the process of pushing the positioning element at the end of the sensor, the locking element moves synchronously to automatically increase the clamping force. This ensures reliable contact between the sensor and the positioning element and avoids positioning deviation caused by insufficient clamping force, thereby improving the accuracy of the cutting reference.

[0018] 2. By measuring the resistance generated by the return spring when the contact plate is compressed, the operator or control system can sense the tightness of the sensor clamping in real time. If the resistance is too high or too low, it can be adjusted in time, effectively avoiding processing defects caused by improper clamping. At the same time, the compression stroke of the return spring is related to the movement displacement of the fixed cylinder. When the sensor end pushes the contact plate to the designated position, the spring resistance is stable and repeatable, ensuring that the sensor is pushed to the same reference point every time, significantly improving the consistency of detection and cutting positions.

[0019] 3. The pushing frame presses inward against the clamping plate, causing the pressing plate to move outward towards the sensor, further clamping the sensor. The device automatically adjusts the clamping effect to prevent loosening during subsequent cutting. Driven by friction between the contact wheel and the sensor surface, the device automatically triggers a force-increasing mechanism when insufficient clamping is detected, further pressing the sensor with the pressing plate. This process requires no external sensor or control system intervention, responds quickly, and effectively prevents axial movement or radial wobble of the sensor during subsequent cutting due to insufficient clamping force.

[0020] 4. After the airbag inflates, it comes into contact with the outside of the sensor, increasing the tightness of the pressure on the sensor and making the airbag fit closely to the sensor surface. This effectively reduces vibration during subsequent cutting. By pushing the frame to move, the air cylinder piston is compressed, and the airbag is inflated by using gas as the transmission medium. The surface of the airbag can deform uniformly with the shape of the sensor, adaptively fitting the outer wall of the sensor. It is especially suitable for non-cylindrical or irregularly shaped sensors with protrusions on the surface, significantly improving the clamping contact area and uniformity.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0026] like Figures 1 to 10 As shown, a cutting fixture device for adjusting the sensor detection distance includes the following embodiments: The system includes a fixed bracket 1, with a fixed plate 101 fixedly connected to the outside of the fixed bracket 1, and also includes: The testing mechanism is located on the top of the fixed plate 101 and is used to test the sensing distance of the sensor to be processed. The sliding plate 2 is slidably disposed on the top of the fixed bracket 1, and two fixed platforms 3 are fixedly connected to the top of the sliding plate 2. The two fixed platforms 3 are provided with receiving grooves inside, and the two fixed platforms 3 can be alternately switched to the front side of the detection mechanism in the middle of the fixed plate 101. A positioning element is disposed inside the receiving groove and is used to abut against the end of the sensor to define the axial position of the sensor; A fixing cylinder 4 is disposed inside the receiving groove, and a clamping assembly is provided inside the fixing cylinder 4. The clamping assembly includes: Multiple clamping components are movably disposed within the receiving groove and can be relatively retracted or expanded for clamping or releasing the sensor; Multiple contact elements are respectively disposed on each clamping element for contacting the sensor surface; The flexible traction mechanism is located on the outside of the clamping member. The flexible traction mechanism is driven by the friction between the contact member and the sensor. A locking element is located on the outside of the clamping element. The locking element is linked with the flexible traction mechanism. When the flexible traction mechanism is activated, it drives the locking element to move, thereby increasing the clamping force of the clamping element on the sensor. And a drive mechanism for driving the fixed cylinder 4 to move along the receiving groove, so that the end of the sensor clamped in the clamping assembly abuts against the positioning member, and pushes the positioning member to a preset position.

[0027] In practice, the operator places the sensor to be processed into the receiving slot of the fixed platform 3, and then clamps and fixes the sensor using the clamping assembly inside the fixed cylinder 4. The sliding plate 2 is moved by a lead screw or electric slide rail installed inside the fixed bracket 1. When the fixed platform 3 holding the sensor moves to the front of the detection mechanism, another fixed platform 3 moves to the other end of the fixed bracket 1, at which point the operator can remove the sensor after detection. During the movement, the drive mechanism moves the fixed cylinder 4 towards the positioning component, causing the sensor end in the clamping assembly to abut against the positioning component. While pushing the positioning component, the friction between the contact component and the sensor drives the flexible traction mechanism. When the flexible traction mechanism operates, it drives the locking component to increase the clamping force on the sensor. This ensures accurate contact between the sensor end and the positioning component, and the stability of the clamping can be detected by the resistance change during the pushing process, further enhancing clamping stability and preventing sensor wobbling during subsequent cutting.

[0028] The flexible traction mechanism is driven by the friction between the contact element and the sensor surface. During the process of pushing the positioning element at the end of the sensor, the locking element moves synchronously to automatically increase the clamping force. This ensures reliable contact between the sensor and the positioning element and avoids positioning deviation caused by insufficient clamping force, thereby improving the accuracy of the cutting reference.

[0029] In this embodiment, the positioning component includes a contact plate 5, which is disposed inside the receiving groove. A mounting bracket 501 is fixedly connected to the outside of the fixing platform 3. A reset spring 503 is fixedly connected between the mounting bracket 501 and the contact plate 5. A contact rod 502 is fixedly connected to the side of the contact plate 5 near the mounting bracket 501.

[0030] In practical implementation, a contact plate 5 is installed in the receiving groove. When the clamped sensor contacts the contact plate 5, a return spring 503 is provided between the contact plate 5 and the mounting bracket 501. The fixed cylinder 4 is moved by the drive mechanism, and the return spring 503 provides resistance to detect the degree of clamping of the sensor by the clamping assembly and ensure that the sensor reaches the designated detection position with the drive mechanism. By measuring the resistance generated by the return spring 503 when the contact plate 5 is compressed, the operator or control system can sense the tightness of the sensor clamping in real time. If the resistance is too large, it indicates that the clamping is too tight and may damage the device, or if the clamping is too small, it is too loose and may easily shift. Adjustments can be made in time to effectively avoid processing defects caused by improper clamping. At the same time, the compression stroke of the return spring is related to the movement displacement of the fixed cylinder 4. When the sensor end pushes the contact plate 5 to the designated position, the spring resistance is stable and repeatable, ensuring that the sensor can be pushed to the same reference point each time, which significantly improves the consistency of the detection and cutting positions.

[0031] Example 2: The clamping component includes a clamping plate 6, and an electric push rod 601 is fixedly connected inside the fixed cylinder 4. The telescopic end of the electric push rod 601 is fixedly connected to the clamping plate 6, and the multiple clamping plates 6 are all arc-shaped relative to each other.

[0032] The contact element includes a contact wheel 801. A through groove is provided at one end of the clamping plate 6 away from the positioning element. The contact wheel 801 is provided inside the through groove. Both ends of the contact wheel 801 pass through the clamping plate 6 and are rotatably connected to the clamping plate 6. Both ends of the contact wheel 801 are connected to a third gear 802 through a one-way bearing. The outer side of the contact wheel 801 is in contact with the outside of the sensor.

[0033] The locking component includes a pressing plate 7 and a clamping plate 6 with a placement groove. The pressing plate 7 is placed inside the placement groove and is inclined near the fixed cylinder 4. Both ends of the pressing plate 7 are fixedly connected to connecting plates 701. A first spring 702 is fixedly connected between the connecting plate 701 and the clamping plate 6. A push frame 703 is slidably connected to the outside of the clamping plate 6 and contacts one side of the pressing plate 7. When the push frame 703 moves, it pushes the pressing plate 7 down to lock the sensor surface.

[0034] The flexible traction mechanism includes a rotating rod 804, a support plate fixedly connected to the outside of the clamping plate 6, the rotating rod 804 passing through the support plate and rotatably connected to the support plate, a fourth gear 803 fixedly connected to both ends of the rotating rod 804, the fourth gear 803 meshing with the third gear 802, a take-up reel 805 fixedly connected to the outside of the rotating rod 804, a tensioning wire 807 wound and fixedly attached to the outside of the take-up reel 805, and the tensioning wire 807 fixedly connected to the push frame 703.

[0035] In practice, by driving the electric push rods 601 inside the fixed cylinder 4, multiple electric push rods 601 push multiple clamping plates 6 to tighten together, and the multiple clamping plates 6 clamp and fix the sensor around its exterior. Then, the fixed cylinder 4 is moved by the driving mechanism, at which point the clamped end of the sensor comes into contact with the positioning element. As the sensor pushes the positioning component to move, resistance exists. If the external clamping of the sensor is not tight enough, the contact wheel 801 moves relative to the sensor, causing the contact wheel 801 to rotate. This rotation drives the third gear 802, connected to it via a one-way bearing, to rotate. The third gear 802 drives the meshing fourth gear 803, which in turn drives the fixedly connected rotating rod 804. The rotating rod 804 then drives the fixedly connected winding reel 805 to rotate. The winding reel 805 winds and winds the tension wire 807, which is fixedly connected to its exterior. The tension wire 807 pulls the push frame 703 towards the winding reel 805. At this time, the push frame 703 presses inward against the clamping plate 6, causing the pressing plate 7 to move outward towards the sensor, further clamping the sensor. This automatically adjusts the clamping effect on the sensor, preventing loosening during subsequent cutting. This device is driven by the friction between the contact wheel 801 and the sensor surface. When insufficient clamping is detected, it is automatically triggered, causing the pressing plate 7 to further press the sensor. This process requires no external sensors or control system intervention, responds quickly, and effectively avoids axial movement or radial sway of the sensor during subsequent cutting due to insufficient clamping force.

[0036] In this embodiment: a ratchet 9 is fixedly connected to the outside of the rotating rod 804, a fixing frame 903 is fixedly connected to the outside of the clamping plate 6, a pawl 901 is connected to the outside of the fixing frame 903 by a torsion spring, the pawl 901 limits the ratchet 9 in one direction, and a fixing rod 902 is fixedly connected to the inner wall of the fixing cylinder 4. When the clamping plate 6 is reset and raised, the fixing rod 902 contacts one end of the pawl 901, so that the pawl 901 releases the limitation on the ratchet 9.

[0037] In practical implementation, to ensure that the sensor clamping does not loosen, this solution has a ratchet 9 fixedly connected to the outside of the rotating rod 804. The ratchet 9 is locked and limited by the pawl 901 on the outside of the ratchet 9, preventing the rotating rod 804 from reversing, thereby maintaining the winding state of the winding reel 805 on the tension wire 807, and ensuring that the extrusion plate 7 continuously maintains the force-increasing clamping of the sensor. When the clamping plate 6 is subsequently reset, the fixing rod 902 squeezes the pawl 901, causing it to deflect. This releases the pawl 901 from the ratchet 9, allowing the push frame 703 to reset under the action of the second spring 709, preparing for the next winding.

[0038] Example 3: An airbag 704 is fixedly connected to the outside of the clamping plate 6. An air cylinder 706 is fixedly connected to both sides of the clamping plate 6. The air cylinder 706 and the airbag 704 are fixedly connected through a connecting pipe. A push plate 708 is slidably connected inside the air cylinder 706. A sliding rod 707 is fixedly connected to the outside of the push plate 708. The sliding rod 707 passes through one end of the air cylinder 706 and is slidably connected to the air cylinder 706. The sliding rod 707 is fixedly connected to the push frame 703. A second spring 709 is sleeved on the outside of the sliding rod 707. The two ends of the second spring 709 are fixedly connected to the push plate 708 and the air cylinder 706, respectively.

[0039] In practice, when the push frame 703 moves, sliding rods 707 are fixedly connected to both sides of the push frame 703. The sliding rods 707 drive the push plate 708, which is fixedly connected to them, to slide inside the air cylinder 706, injecting the gas in the air cylinder 706 into the air bag 704 through the connecting pipe, causing the air bag 704 to inflate. After inflating, the air bag 704 comes into contact with the outside of the sensor, increasing the tightness of the pressure on the sensor and making the air bag closely fit the sensor surface. This effectively reduces vibration during subsequent cutting. The movement of the push frame 703 drives the air cylinder piston to compress, and the air bag expands using gas as the transmission medium. The surface of the air bag can deform uniformly according to the shape of the sensor, adaptively fitting the outer wall of the sensor. This is especially suitable for non-cylindrical or irregularly shaped sensors with protrusions on the surface, significantly improving the clamping contact area and uniformity.

[0040] In embodiment four, the driving mechanism includes a sliding block 402. The sliding block 402 is fixedly connected to the outside of the fixed cylinder 4. A sliding groove is opened inside the fixed platform 3. A driving screw 403 is rotatably connected inside the sliding groove. The driving screw 403 passes through the sliding block 402 and is connected to the sliding block 402 through a ball nut. A side plate 401 is connected to the outside of the fixed cylinder 4. The side plate 401 is slidably engaged with the fixed platform 3. A driving gear 404 is fixedly connected to one end of the driving screw 403. A rack 405 is fixedly connected to the top of the fixed bracket 1. The rack 405 is meshed with the driving gear 404.

[0041] The detection mechanism includes a sensing plate 11, a detection plate 111 fixedly connected to the bottom of the sensing plate 11, and a drive screw rotatably connected to the fixed plate 101. The drive screw passes through the detection plate 111 and is connected to the sensing plate 11 through a ball nut pair.

[0042] In practice, when the sliding plate 2 moves on the fixed bracket 1 via a lead screw or electric slide rail, the drive gear 404 at one end of the drive lead screw 403 meshes with the rack 405. When the fixed platform 3 moves to the front of the detection mechanism, the meshing of the drive gear 404 and the rack 405 causes the drive gear 404 to rotate. This, in turn, drives the sliding block 402 and the fixed cylinder 4 towards the detection mechanism via the drive lead screw 403, until they reach the detection position. Simultaneously, the fixed cylinder 4 inside the other fixed platform 3 returns to its original position, allowing the operator to retrieve the processed sensor and reposition the sensor to be processed. This alternating cycle enables alternating processing between the two fixed platforms 3, significantly improving the overall efficiency of processing and detection.

[0043] While one fixed platform 3 carries the sensor into the detection / cutting station, the fixed cylinder 4 of the other fixed platform 3 automatically returns to its original position. The operator can simultaneously remove the finished product and clamp the blank. The loading and unloading time overlaps with the processing time, realizing zeroing of non-processing auxiliary time and significantly improving equipment utilization and output per unit time.
