DETAILED DESCRIPTION
[0024] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.
[0025] The gear ring clamping and positioning tool of the present application is described below in combination with the drawings.
[0026] As shown in the figure: Figures 1 to 4 The gear ring clamping and positioning tool of the present application can include a slide rail frame 100, a mounting plate 200, a rotating sleeve 300, an electric telescopic rod 400, and a locking head 500.
[0027] The mounting plate 200 is slidingly arranged on the slide rail frame 100 and is limited by the positioning pin 101. The mounting plate 200 is provided with an embedded groove 201, and the rotating sleeve 300 is rotatably embedded in the embedded groove 201. The electric telescopic rod 400 is arranged at the bottom of the mounting plate 200, and the telescopic end of the electric telescopic rod 400 penetrates the rotating sleeve 300. The locking head 500 is detachably arranged on the telescopic end of the electric telescopic rod 400.
[0028] The shaft sleeve 601 of the gear ring 600 is sleeved on the rotating sleeve 300, and the locking head 500 is pressed on the inner wall of the gear ring 600.
[0029] Specifically, when the relevant staff detects the inner teeth of the gear ring 600 or cleans or paints the surface of the gear ring 600, first, the shaft head sleeve 601 of the gear ring 600 is sleeved on the rotating sleeve 300, then the electric telescopic rod 400 is started, the telescopic end of the electric telescopic rod 400 is stretched upwards, then the locking head 500 is installed on the telescopic end of the electric telescopic rod 400, and the electric telescopic rod 400 is controlled to be retracted downwards, so that the locking head 500 abuts against the inside of the gear ring 600.
[0030] Since the rotating sleeve 300 is rotatably embedded in the embedding groove 201 of the mounting plate 200, when the operator needs to rotate the gear ring 600, only an external force needs to be manually applied to the gear ring 600, and the gear ring 600 will drive the rotating sleeve 300 to rotate in the embedding groove 201, so that the angle of the gear ring 600 is adjusted, and the machining, detection and other operations of different parts of the gear ring 600 are facilitated. During rotation, the cooperation between the rotating sleeve 300 and the embedding groove 201 ensures the stability and flexibility of rotation, and also ensures that the gear ring 600 will not be separated from the tooling during rotation.
[0031] When the gear ring 600 needs to be transferred to the next process after the previous process is completed, the relevant staff first pulls out the positioning pin 101, then pushes the mounting plate 200 to slide on the slide rail frame 100, moves the mounting plate 200 to the required position, and then limits the mounting plate 200 again through the positioning pin 101, so as to realize flexible positioning and transfer of the tooling on the production line, and meet the requirements of different production links for machining or detection positions of the gear ring 600.
[0032] In an embodiment of the present application, a plurality of positioning holes 102 are formed in the length direction of the slide rail frame 100, and the positioning pin 101 passes through the corresponding positioning hole 102 to limit the mounting plate 200 on the slide rail frame 100.
[0033] It should be noted that, compared with the design of a single fixed position, this multi-hole positioning method allows the entire tooling to quickly adapt to diversified production processes, reduces the time consumed by recalibrating the position of the mounting plate 200, improves production efficiency, and precise position fixing also helps to ensure the machining and detection accuracy of each process.
[0034] In an embodiment of the present application, as shown in Figure 6 The rotating sleeve 300 includes a cylinder body 310, a support portion 320 and an embedding portion 330.
[0035] The support portion 320 is arranged at the bottom outer circle of the cylinder body 310, the embedding portion 330 is arranged at the bottom outer circle of the support portion 320, the embedding portion 330 is embedded in the embedding groove 201, and the embedding portion 330 and the embedding groove 201 are provided with the rollable ball 301 therebetween.
[0036] When the shaft head sleeve 601 of the gear ring 600 is sleeved on the rotating sleeve 300, the inner wall of the shaft head sleeve 601 is tightly attached to the outer wall of the cylinder body 310, and the bottom of the shaft head sleeve 601 is abutted on the supporting part 320.
[0037] It should be noted that when the shaft head sleeve 601 of the gear ring 600 is sleeved on the rotating sleeve 300, the inner wall of the shaft head sleeve 601 is tightly attached to the outer wall of the cylinder body 310, and the bottom of the shaft head sleeve 601 is abutted on the supporting part 320, which can uniformly disperse the weight and external force borne by the gear ring 600, prevent the gear ring 600 from shaking, deviating and other unstable conditions during machining and detection, ensure the operation precision, and ensure the quality consistency of the final product.
[0038] In addition, the rollable ball 301 is arranged between the embedding part 330 and the embedding groove 201, the ball 301 changes the original sliding friction into rolling friction, greatly reduces the friction force suffered by the rotating sleeve 300 when rotating in the embedding groove 201, and makes the operation more labor-saving.
[0039] In an embodiment of the present application, as shown in Figure 5 The locking head 500 comprises a pressing plate 510 and a threaded rod 520.
[0040] The pressing plate 510 is rotatably arranged on one end of the threaded rod 520, the telescopic end of the electric telescopic rod 400 is provided with a threaded hole 401, and the other end of the threaded rod 520 is threadedly connected in the threaded hole 401.
[0041] It should be noted that when the gear ring 600 is rotated by the relevant staff, the pressing plate 510 can be rotated with the gear ring 600 because the pressing plate 510 is rotatably arranged on the threaded rod 520 and abuts on the gear ring 600 due to the contraction of the electric telescopic rod 400.
[0042] As a possible case, the side surface of the pressing plate 510 close to the gear ring 600 is provided with a rubber buffer layer, and the thickness of the rubber buffer layer is 2-3 mm, so as to prevent the pressing plate 510 from directly rigidly contacting the inner wall of the gear ring 600 and causing scratches, indentations and other damages to the surface of the gear ring 600 under the action of the pressing force, especially for some gear rings 600 with high surface precision requirements, these small damages may affect the performance and service life.
[0043] In an embodiment of the present application, in order to facilitate the movement of the mounting plate 200, at least two handles are arranged on the mounting plate 200, and the handles are arranged on the two sides of the mounting plate 200 respectively.
[0044] It should be noted that the relevant staff can push and pull the corresponding handle according to the moving direction, so that the mounting plate 200 can smoothly move on the slide rail frame 100.
[0045] In conclusion, according to the gear ring clamping and positioning tool, the cooperation of the shaft head sleeve 601 of the gear ring 600 and the rotating sleeve 300 and the pressing effect of the locking head 500 realize that the gear ring 600 can rotate in the state of being firmly clamped, so that the processing or detection process of the gear ring 600 is more convenient; in addition, the mounting plate 200 is slidingly arranged on the sliding rail frame 100 and is limited by the positioning pin 101, so that the mounting plate 200 can be conveniently moved on the sliding rail frame 100 according to production requirements, the versatility and flexibility of the equipment are enhanced, and the equipment is suitable for different production layouts and process flows.
