DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0034] Embodiment 1: A positioning device for gearbox processing, such as Figures 1 to 7As shown, the frame 101 includes a frame 101, a fixed frame 102 is fixedly connected to the left side of the top of the frame 101, and a first sliding frame 103 is slidably connected to the right side of the fixed frame 102 along the left and right directions. The end surfaces of the fixed frame 102 and the first sliding frame 103 that are close to each other are both provided with comb grooves, and the comb grooves of the fixed frame 102 and the comb grooves of the first sliding frame 103 are staggered and engaged, and the fixed frame 102 and the first sliding frame 103 are both provided with rectangular through holes, and the tops of the fixed frame 102 and the first sliding frame 103 are used to place The gear box 1021 has four legs with positioning holes. The bottoms of the fixed frame 102 and the first sliding frame 103 are slidably connected to two second sliding frames 104 along the front-back direction. The fixed frame 102 and the first sliding frame 103 are fixedly connected to the side close to the adjacent rectangular through hole with a latch 105. The two second sliding frames 104 on the left are fixedly connected to the motor 106. The second sliding frame 104 is inserted with a first screw 107. The first screw 107 is limited by the adjacent rectangular through hole. The second sliding frame 104 is slidably connected to the limit block 108 in the left and right directions, and the limit block 108 has a limit groove. The first screw 107 is inserted between the positioning hole of the gear box 1021 and the limit groove of the adjacent limit block 108, and is used to connect the gear box 1021 to the four second sliding frames 104. The second sliding frame 104 is rotatably connected to the rotating shaft 109, and the adjacent rotating shafts 109 are splined with shaft sleeves 110. The side of the second sliding frame 104 close to the adjacent latch teeth 105 is connected along the upper and lower sides. A block 111 is slidably connected thereto, and the block 111 moves upward to engage with the adjacent locking tooth 105. A first cam 112 is rotatably connected thereto in the second sliding frame 104. The limit block 108 and the adjacent first cam 112 are limited by a thread groove. The rotating shaft 109 is fixedly connected to the adjacent first cam 112. A second cam 201 is fixedly connected to one side of the rotating shaft 109 close to the adjacent block 111. The second cam 201 will squeeze the block 111 to move toward the adjacent locking tooth 105 during its rotation.

[0035] First, four positioning holes are punched on the four corners of the gear box 1021, and the gear box 1021 is placed between the fixed frame 102 and the first sliding frame 103. The length of the first sliding frame 103 pulled to the right is adjusted according to the length of the gear box 1021, and then the distance between the two adjacent second sliding frames 104 in front and behind is adjusted according to the width of the gear box 1021, so that the four positioning holes of the support feet of the gear box 1021 are respectively aligned with the limiting grooves of the four limiting blocks 108. Then, the four first screw rods 107 are respectively inserted between the four positioning holes and the limiting grooves, and then the output shaft of the motor 106 is controlled to drive the first cam 112 on the left to rotate, thereby driving the rotating shaft 109 on the left to rotate, and then driving the shaft sleeve 110 to rotate, and then driving the rotating shaft 109 on the right to rotate. The rotating shaft 109 on the right side drives the first cam 112 on the right side to rotate. The rotation of the first cam 112 will cause the adjacent limit block 108 to slide horizontally toward the side close to the adjacent first screw rod 107 until it is stuck with the adjacent first screw rod 107. In this way, the gear box 1021 is fixed on the second sliding frame 104. At the same time, the rotation of the first cam 112 drives the second cam 201 to rotate synchronously. When the protrusion of the second cam 201 rotates to contact the block 111, the block 111 is pushed up to be stuck in the adjacent tooth 105. In this way, the second sliding frame 104 is fixed on the corresponding fixed frame 102 and the first sliding frame 103. After the processing is completed, the gear box 1021 can be released by controlling the output shaft of the motor 106 to reverse.

[0036] In summary, the present invention can adapt to the processing and positioning of gear boxes 1021 of different lengths by adjusting the first sliding frame 103 to the left and right, and can adapt to the processing and positioning of gear boxes 1021 of different widths by adjusting the second sliding frame 104 to the front and back. By starting the motor 106, the limit block 108 can automatically lock the first screw 107, and the latch tooth 105 can automatically lock the latch block 111, so that the gear box 1021 is completely fixed, the operation is simple and convenient, and the stability of the gear box 1021 during processing can be improved.

[0037] Embodiment 2: Based on embodiment 1, Figure 8 As shown, a second screw rod 301 is also included. The second screw rod 301 is threadedly connected to the right side of the fixed frame 102 . The second screw rod 301 is rotatably connected to the first sliding frame 103 . The right end of the second screw rod 301 is fixedly connected to a rotating wheel 302 .

[0038] By rotating the rotating wheel 302 forward or reversely, the second screw rod 301 moves leftward or rightward, thereby driving the first sliding frame 103 to move leftward or rightward, so that the adjustment operation of the first sliding frame 103 is more precise and the adjusted first sliding frame 103 is more stable.

[0039] Embodiment 3: Based on embodiment 2, Fig. 9 and Fig.10 As shown, four pointing blocks 401 are also included. The pointing blocks 401 are fixedly connected to the adjacent second sliding frame 104. The pointing blocks 401 are arranged in a T-shape. The pointing blocks 401 are aligned with the limiting grooves of the adjacent limiting blocks 108. The tops of the pointing blocks 401 are located at the tops of the fixed frame 102 and the first sliding frame 103. The fixed frame 102 and the first sliding frame 103 are both provided with sliding grooves 402. The pointing blocks 401 are slidably connected to the adjacent sliding grooves 402. The pointing blocks 401 penetrate the adjacent sliding grooves 402 upward.

[0040] When the second sliding frame 104 moves forward and backward, the pointing block 401 slides forward and backward synchronously along the sliding groove 402. When the four positioning holes of the gear box 1021 support leg are aligned with the limiting grooves of the four limiting blocks 108 respectively, since the limiting grooves of the limiting blocks 108 are below the positioning holes of the gear box 1021 and are invisible from a normal perspective, the alignment operation is difficult. Therefore, the alignment of the positioning holes of the gear box 1021 with the limiting grooves of the limiting blocks 108 is converted into the alignment of the positioning holes of the gear box 1021 with the corresponding pointing blocks 401, so that the alignment is visualized and the difficulty of the alignment operation is reduced.

[0041] like Figure 11 to Figure 12 As shown, four handles 501 are also included. The handles 501 are slidably connected to the adjacent second sliding frames 104. The top ends of the handles 501 are fixedly connected with gripping blocks 502. The gripping blocks 502 are located in adjacent rectangular through holes.

[0042] When moving the second sliding frame 104 forward and backward, it is inconvenient to operate because it needs to be pushed and adjusted from the bottom. Therefore, by holding the gripping block 502 and pulling the handle 501 upward, the handle 501 is extended upward out of the rectangular through hole, and then the second sliding frame 104 is pushed by pushing the handle 501, thereby reducing the difficulty of moving the second sliding frame 104.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
