[0002] A gear is a mechanical component with teeth on the rim that can continuously mesh to transmit motion and power. As an important component of the mechanical transmission system, it has a wide range of applications. It requires multiple processing steps during processing. Different processing steps will use corresponding fixtures to clamp and fix the gears, thereby facilitating the processing of the gears.

[0003] When the existing gear processing clamping tool is used to flip the gear, the gear needs to be removed from the clamping tool and re-clamped and fixed. The gear needs to be repositioned during processing, which increases the workload of gear processing and takes a long time, affecting the speed of gear processing. Therefore, improvement is needed. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a clamping tool for gear processing, which solves the problem that the existing clamping tool for gear processing cannot directly flip the gear on the top of the clamping tool when flipping the gear, affecting the gear processing speed.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping tool for gear processing, comprising an adjusting mechanism, a clamping mechanism is symmetrically and slidably installed on both sides of the adjusting mechanism, the clamping mechanism comprises an adjusting plate, a clamping rod is symmetrically and fixedly installed on one side of the adjusting plate, and a connecting plate is fixedly installed on one end of two groups of clamping rods, and fixed pressure plates are slidably installed on the surfaces of the two groups of clamping rods, a fixing spring is provided on the surface of the clamping rod between the connecting plate and the fixed pressure plate, and rotating plates are rotatably installed on the opposite sides of the two groups of clamping mechanisms, a rotating column is fixedly installed at the central position of one side of the rotating plate, and a positioning plate is fixedly installed on the end of the rotating column away from the rotating plate, a plurality of groups of fixed jacks are provided at equal angles on the surface of the positioning plate, a clamping plate is provided on the side of the rotating plate away from the clamping mechanism, and a gear body is provided between the two groups of clamping plates.

[0006] As a further solution of the utility model: the adjustment mechanism includes two groups of adjustment screws, and end plates are fixedly installed at both ends of the two groups of adjustment screws, and fixed screw sleeves are symmetrically provided on both sides of the surface of the adjustment screws.

[0007] As a further solution of the utility model: the end plate is provided with a first sliding groove between the two groups of adjusting screws, and two groups of sliding rods are slidably installed between the two groups of first sliding grooves.

[0008] As a further solution of the utility model: a second slide groove is provided at the bottom of the adjustment plate, and the second slide groove corresponds to the first slide groove, and the slide rod passes through the second slide groove.

[0009] As a further solution of the utility model: an arc-shaped groove is provided on one side of the fixed pressure plate close to the adjustment plate, and fixed clamping columns are symmetrically fixedly installed inside the arc-shaped groove, and the fixed clamping columns correspond to the fixed sockets.

[0010] As a further solution of the utility model: fixing bolts are fixedly installed at both ends of the clamping plate close to the rotating plate, and one end of the fixing bolt passes through the rotating plate and is provided with a fixing nut.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The clamping tool for gear processing is provided with a fixed pressure plate, a fixed clamping column, a fixed spring, a rotating plate and a positioning plate. The fixed pressure plate is pulled to make the fixed clamping column away from the fixed socket, so that the rotating plate can drive the clamping plate and the gear body to rotate.

The two sets of sliding rods are moved until the gear body can be placed on the top of the two sets of sliding rods. The two sets of adjusting plates are pushed to move on the surface of the adjusting screw until the clamping plate is pressed against the surface of the gear body. The fixing screw sleeve is tightened to press against one side of the adjusting plate so that the clamping plate clamps and fixes the gear body. It is convenient to adjust the distance between the two sets of clamping plates according to the size of the gear body and clamp and fix gear bodies of different sizes.

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a clamping tool for gear processing, including an adjusting mechanism 1, the adjusting mechanism 1 includes two groups of adjusting screws 101, and the two ends of the two groups of adjusting screws 101 are fixedly installed with end plates 102, and fixed screw sleeves 103 are symmetrically provided on both sides of the surface of the adjusting screw 101. Because the fixed screw sleeves 103 are provided, the fixed screw sleeves 103 are adjusted at different positions on the surface of the adjusting screw 101 to adjust the position of the adjusting plate 201, ensuring that the clamping plate 4 can be clamped on the surface of the gear body 5.

[0021] The end plate 102 is located between the two groups of adjusting screws 101 and is provided with a first sliding groove 104, and two groups of sliding rods 105 are slidably installed between the two groups of first sliding grooves 104. By providing the sliding rods 105, the distance between the two groups of sliding rods 105 can be adjusted according to the size of the gear body 5 to ensure that the two groups of sliding rods 105 can be tightly attached to the bottom of the gear body 5 when the gear body 5 is horizontally clamped on the top of the adjusting mechanism 1, thereby supporting the gear body 5 and preventing the gear body 5 from falling off the clamping plate 4 during processing.

[0022] The clamping mechanism 2 is symmetrically and slidably installed on both sides of the adjustment mechanism 1, and the clamping mechanism 2 includes an adjustment plate 201. A second slide groove 202 is provided at the bottom of the adjustment plate 201, and the second slide groove 202 corresponds to the first slide groove 104, and the slide rod 105 passes through the second slide groove 202. Because the second slide groove 202 is provided, it is convenient to adjust the slide rod 105 to move inside the second slide groove 202 according to the size of the gear body 5.

[0023] A clamping rod 203 is symmetrically fixedly installed on one side of the adjustment plate 201, and a connecting plate 204 is fixedly installed on one end of the two groups of clamping rods 203. A fixed pressure plate 205 is slidably installed on the surface of the two groups of clamping rods 203. An arc groove 206 is provided on the side of the fixed pressure plate 205 close to the adjustment plate 201, and a fixed clamping column 207 is symmetrically fixedly installed inside the arc groove 206, and the fixed clamping column 207 corresponds to the fixed socket 303. By providing the arc groove 206, the positioning plate 302 can rotate inside the arc groove 206 when the rotating plate 3 rotates, ensuring that the fixed socket 303 can correspond to the fixed clamping column 207.

[0024] A fixing spring 208 is provided on the surface of the clamping rod 203 between the connecting plate 204 and the fixed pressing plate 205. Due to the fixing spring 208, the fixed pressing plate 205 is pressed against the surface of the positioning plate 302 under the elastic action of the fixing spring 208, ensuring that the fixing clamping column 207 can be inserted into the corresponding fixing socket 303 to clamp and fix the positioning plate 302;

[0025] The rotating plates 3 are rotatably mounted on the opposite sides of the two sets of clamping mechanisms 2, and a rotating column 301 is fixedly mounted at the central position of one side of the rotating plate 3, and a positioning plate 302 is fixedly mounted on the end of the rotating column 301 away from the rotating plate 3.

Due to the fixed plug holes 303, after the fixed clamping column 207 is inserted into the corresponding fixed plug hole 303, it is ensured that the positioning plate 302 will not rotate inside the arc groove 206, and the rotating plate 3 and the clamping plate 4 are clamped and fixed, so that the gear body 5 will not rotate at will during processing, which will affect the processing;

[0026] A clamping plate 4 is provided on the side of the rotating plate 3 away from the clamping mechanism 2, and fixing bolts 401 are fixedly installed at both ends of the clamping plate 4 close to the rotating plate 3, and one end of the fixing bolt 401 passes through the rotating plate 3 and is provided with a fixing nut 402.

[0027] The working principle of the utility model is:

[0028] After fixing the corresponding clamping plate 4 on one side of the rotating plate 3 according to the gear body 5, adjust the distance between the two sets of slide bars 105 so that the gear body 5 can be placed on the top of the two sets of slide bars 105, push the two sets of adjustment plates 201 until the clamping plate 4 is close to the surface of the gear body 5, screw the fixing screw sleeve 103 to clamp and fix the adjustment plate 201, ensure that the clamping plate 4 is clamped and fixed to the gear body 5, and after the surface processing of the top of the gear body 5 is completed, push the two sets of slide bars 105 to both sides to make the slide bars 105 away from the gear body 5. , pull the fixed pressure plate 205 to both sides to make the fixed clamping column 207 disengage from the corresponding fixed socket 303, flip the gear body 5 to make the fixed clamping column 207 correspond to the fixed socket 303, loosen the fixed pressure plate 205, and cover the fixed pressure plate 205 on the surface of the positioning plate 302 under the rebound action of the fixed spring 208, ensure that the fixed clamping column 207 is inserted into the corresponding fixed socket 303, clamp and fix the rotating plate 3, and then move the two sets of sliding rods 105 to the bottom of the gear body 5 to process the gear body 5.
