Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a two-plane fixture for boring machines used in the production of spherical universal joints. Background Technology

[0002] In the production of spherical universal joints, the boring accuracy of the universal joint fork and the machining accuracy of the two planes directly affect the assembly quality and service life of the universal joint. This process requires a special fixture to achieve workpiece positioning and clamping. Currently, the industry generally uses special fixtures for boring machines that include chucks, limit components, and clamping components. However, existing fixtures have significant defects in actual mass production and are difficult to meet the requirements of high-precision machining: First, the positioning datum is singular, relying solely on the fit between the fork lug end face and the limit block for positioning. If the universal joint fork blank has casting deformation or insufficient precision of the pre-machined datum surface, it is easy to cause the positioning datum to shift, resulting in out-of-tolerance boring coaxiality and parallelism of the two planes; Second, the cutting force during machining will cause slight movement of the workpiece, and existing fixtures lack real-time positioning monitoring and dynamic compensation structures, making it impossible to correct this displacement error in time, further aggravating the fluctuation of machining accuracy and affecting the overall performance and pass rate of spherical universal joint products.

[0003] Therefore, this utility model provides a two-plane fixture for boring machines used in the production of spherical universal joints. Utility Model Content

Several first infrared rangefinders are installed inside the support ring to monitor the positional changes of the universal joint between the two clamping plates. A first driving part is installed at the bottom of the output end of the adjusting telescopic rod. A cutting head for machining the universal joint is installed at the end of the first driving part. The adjusting telescopic rod is electrically connected to the several first infrared rangefinders.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A two-plane fixture for a boring machine used in the production of spherical universal joints includes a base 1 and two side supports 11. Two limiting telescopic rods 2, a support ring 3 and an adjusting telescopic rod 4 are arranged between the two side supports 11.

[0021] Among them, the limiting telescopic rod 2 is installed on one side of the corresponding side bracket 11. The output end of both limiting telescopic rods 2 is equipped with a clamping plate 21 that is in contact with the universal joint. An anti-slip pad 22 is provided on one side of both clamping plates 21 to increase the friction between them and the universal joint blank.

[0022] It should be noted that the two limiting telescopic rods 2 described in this embodiment are symmetrically distributed and operate synchronously.

[0023] The support ring 3 is located below the two limiting telescopic rods 2. Several first infrared rangefinders 31 are installed on the inner side of the support ring 3 to monitor the positional changes of the universal joint between the two clamping plates 21.

[0024] It should be noted that the first infrared rangefinder 31 described in this embodiment detects the horizontal movement of the universal joint.

[0025] The bottom of the output end of the telescopic rod 4 is equipped with a first drive unit 41, and the end of the first drive unit 41 is equipped with a cutting head 42 for machining the universal joint. The telescopic rod 4 is electrically connected to several first infrared rangefinders 31.

[0026] It should be noted that the first drive unit 41 described in this embodiment is a drive motor, and the adjustment telescopic rod 4 adjusts the position of the first drive unit 41 and the cutter head 42 to adapt to the slight movement of the universal joint and to the grinding and cutting of different positions of the universal joint.

[0027] Specifically, during operation, the spherical universal joint blank is first placed between two symmetrically distributed and synchronously operating limiting telescopic rods 2. The limiting telescopic rods 2 extend, driving the clamping plates 21, which are equipped with anti-slip pads 22 on both sides, to move towards the universal joint blank until the anti-slip pads 22 on the clamping plates 21 press against the universal joint blank. The anti-slip pads 22 increase the friction, and the universal joint blank is initially clamped and positioned. At the same time, several first infrared rangefinders 31 on the inner side of the support ring 3 continuously monitor the horizontal position change of the universal joint blank between the two clamping plates 21. When boring and machining the two planes, the adjusting telescopic rod 4 adjusts the position of the first drive unit 41 and the cutter head 42 so that the cutter head 42 is aligned with the machining position. The first drive unit 41 drives the cutter head 42 to rotate and machine the universal joint. During the machining process, if the universal joint blank experiences slight horizontal movement due to cutting force or other factors... The first infrared rangefinder 31 detects this position change in real time and transmits the signal to the adjusting telescopic rod 4. The adjusting telescopic rod 4 adjusts the position of the first drive unit 41 and the cutter head 42 in a timely manner according to the signal, so as to adapt to the slight movement of the universal joint blank. This ensures that the cutter head 42 can always accurately process the universal joint, and can also grind and cut different positions of the universal joint. The first infrared rangefinder 31 on the inner side of the support ring 3 can monitor the horizontal position change of the universal joint in real time. The adjusting telescopic rod 4 is electrically connected to the first infrared rangefinder 31. When a slight movement of the universal joint is detected, the adjusting telescopic rod 4 can adjust the position of the first drive unit 41 and the cutter head 42 in a timely manner, realizing real-time positioning monitoring and dynamic compensation, effectively correcting displacement errors, solving the problem of machining accuracy fluctuations, and thus ensuring the overall performance and pass rate of the spherical universal joint product.

[0028] In one embodiment of this utility model, such as Figures 1-4 As shown, a fixing ring 5 is provided between the two bases 1, and a rotating ring 51 is rotatably connected to the inner side of the fixing ring 5. The adjustment telescopic rod 4 is installed inside the rotating ring 51.

[0029] It should be noted that, as described in this embodiment, the rotating ring 51 drives the adjusting telescopic rod 4 to rotate in order to adjust the position of the rotating ring 51 and the third drive unit 52.

[0030] Specifically, during operation, when machining is required at different circumferential positions of the universal joint, the rotating ring 51 rotatably connected to the inner side of the fixed ring 5 can drive the adjusting telescopic rod 4 installed inside it to rotate, thereby adjusting the circumferential position of the adjusting telescopic rod 4 and the associated first drive unit 41 and cutter head 42. Combined with the adjusting telescopic rod 4's ability to adjust the positions of the first drive unit 41 and cutter head 42 to accommodate minute movements of the universal joint, it allows for more flexible grinding and cutting of different circumferential and radial positions of the universal joint. On the one hand, this structure drives the adjustment telescopic rod 4 to rotate through the rotating ring 51. With the extension and retraction adjustment of the adjustment telescopic rod 4, the adjustable position range of the cutter head 42 is enriched, which can better adapt to non-standard position machining caused by deformation of the universal joint fork blank, and reduce the adverse effects caused by the offset of the positioning reference. On the other hand, during the machining process, the coordinated adjustment of the rotating ring 51 and the adjustment telescopic rod 4 can respond more timely and accurately to the small movement of the universal joint caused by the cutting force, assist in achieving dynamic compensation, and further improve the machining accuracy. This helps to solve the problem of machining accuracy fluctuations affecting product performance and yield.

[0031] In one embodiment of this utility model, such as Figures 1-4 As shown, each of the two side supports 11 has an upper sliding groove 111 and a lower sliding groove 112 on opposite sides. The fixing ring 5 is slidably connected between the two upper sliding grooves 111, and the support ring 3 is slidably connected between the two lower sliding grooves 112.

[0032] Specifically, during operation, the fixed ring 5 can slide along the upper sliding groove 111 on the two side supports 11, achieving horizontal position adjustment; simultaneously, the support ring 3 can slide along the lower sliding groove 112 on the two side supports 11, moving horizontally. By sliding the fixed ring 5 and support ring 3 within their respective grooves, their positions can be flexibly adjusted, thus coordinating with other components to adapt to the positioning and processing operations of the universal joint under different specifications or processing requirements, providing a more flexible position adjustment basis for the precise processing of the universal joint by the entire fixture.

[0033] In one embodiment of this utility model, such as Figures 1-4 As shown, a rotating plate 32 is provided below the support ring 3. The rotating plate 32 is rotatably connected to the top of the base 1. Two second infrared rangefinders 33 are symmetrically arranged at the top of the rotating plate 32 to monitor the lifting and lowering of the universal joint blank. The second infrared rangefinders 33 are electrically connected to the adjustment telescopic rod 4.

[0034] Specifically, during operation, the rotating plate 32 can rotate at the top of the base 1, and two second infrared rangefinders 33 symmetrically arranged at its top continuously monitor the lifting and lowering of the universal joint blank. When the universal joint blank changes position in the lifting and lowering direction during processing, the second infrared rangefinders 33 transmit the monitored signal to the adjusting telescopic rod 4. The adjusting telescopic rod 4 adjusts the height of its output end according to the signal, thereby adjusting the vertical position of the first drive unit 41 and the cutter head 42, so that the cutter head 42 can adapt to the lifting and lowering movement of the universal joint blank, ensuring the processing accuracy of the universal joint blank at different vertical positions.

[0035] In one embodiment of this utility model, such as Figures 1-4 As shown, a second drive unit 12 is embedded in the bottom of the base 1. The output end of the second drive unit 12 is plugged into the bottom of the rotating plate 32. A fixing bolt 34 is provided on the rotating plate 32 to connect and fix the output end of the second drive unit 12.

[0036] It should be noted that the second drive unit 12 described in this embodiment is a motor.

[0037] Specifically, the second drive unit 12, embedded in the bottom of the base 1, provides power. Its output end is plugged into the bottom of the rotating plate 32, and the output end of the second drive unit 12 is connected and fixed to the rotating plate 32 by the fixing bolt 34 on the rotating plate 32, ensuring that the two move synchronously. When it is necessary to adjust the rotation state of the rotating plate 32 to adapt to the monitoring requirements of the universal joint blank, the second drive unit 12 is activated, and its output end drives the rotating plate 32 to rotate at the top of the base 1, thereby driving the second infrared rangefinder 33 at the top of the rotating plate 32 to rotate synchronously. This allows the second infrared rangefinder 33 to accurately monitor the lifting and lowering of the universal joint blank from different angles, providing more comprehensive monitoring data support for the subsequent adjustment of the vertical position of the cutter head 42 by the telescopic rod 4 and ensuring machining accuracy.

[0038] In one embodiment of this utility model, such as Figures 1-4 As shown, a third drive unit 52 is installed on one side of the fixed ring 5 to drive the rotation of the rotating ring 51. The third drive unit 52 is electrically connected to the first infrared rangefinder 31 and the second infrared rangefinder 33.

[0039] It should be noted that the rotating ring 51 described in this embodiment is provided with a toothed ring on its outer side, and a gear is rotatably connected to the inner wall of the third driving part 52. The gear meshes with the toothed ring, and a drive motor is provided at the top of the third driving part 52.

[0040] Specifically, during operation, the third drive unit 52 on one side of the fixed ring 5 engages with the outer gear ring of the rotating ring 51 via a gear rotatably connected to its inner wall, providing rotational power to the rotating ring 51 under the drive of the top drive motor. Since the third drive unit 52 is electrically connected to the first infrared rangefinder 31 and the second infrared rangefinder 33, when the first infrared rangefinder 31 detects a change in the horizontal position of the universal joint blank or the second infrared rangefinder 33 detects its lifting or lowering, it transmits a signal to the third drive unit 52. The third drive unit 52 drives the rotating ring 51 to rotate according to the signal, which in turn drives the adjusting telescopic rod 4 and the related cutter head 42 installed on the inner side of the rotating ring 51 to rotate synchronously. With the extension and retraction adjustment of the adjusting telescopic rod 4, the cutter head 42 is adjusted in the circumferential, radial and vertical directions to ensure that the cutter head 42 can always be accurately aligned with the processing position when the universal joint blank undergoes multi-directional position changes.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] Working principle: During operation, the spherical universal joint blank is first placed between two symmetrically operating synchronous limiting telescopic rods 2. The limiting telescopic rods 2 extend and drive the clamping plate 21 with anti-slip pads 22 to squeeze the blank. The anti-slip pads 22 increase friction to achieve initial clamping and positioning. The first infrared rangefinder 31 on the inner side of the support ring 3 monitors the horizontal movement of the blank in real time, and the second infrared rangefinder 33 on the rotating plate 32 monitors the lifting of the blank. The second drive unit 12 drives the rotating plate 32 to rotate through the fixing bolt 34, so that the second infrared rangefinder 33 can monitor from multiple angles. During processing, the adjusting telescopic rod 4 adjusts the position of the first drive unit 41 and the cutter head 42, and the first drive unit 41 drives the cutter head 42 to process. If the workpiece is displaced, the first and second infrared rangefinders transmit signals to the adjusting telescopic rod 4 and the third drive unit 52. The adjusting telescopic rod 4 adjusts the radial and vertical positions of the cutter head 42, and the third drive unit 52 drives the rotating ring 51 and the adjusting telescopic rod 4 to rotate through gear-ring meshing. With the cooperation of the fixed ring 5 and the support ring 3, the cutter head 42 is adjusted in multiple directions in a coordinated manner along the upper sliding groove 111 and the lower sliding groove 112, respectively, so as to ensure the processing accuracy.
