Description

Technical Field

[0001] The utility model relates to the technical field of hardware, in particular to a thread rolling machine thread processing clamp. Background Art

[0002] A thread rolling machine is a highly efficient thread processing machine widely used in machining. It consists of two rolling wheels. When producing threads on the end of a long shaft, the shaft is typically placed on a support and then pressed against the rolling wheels to roll the threads. Under existing processing methods, manual rotation is required after each long shaft is processed, preventing automated thread handling and reducing the efficiency of rolling operations for batches of long shafts. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a thread rolling machine thread processing fixture.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] The thread rolling machine processes thread fixtures, including a fixture box, which is a hollow cylindrical structure. Two fixed seats, a mounting shaft and a guide cylinder are respectively provided on the inner walls at both ends of the fixture box. Cylinders are rotatably installed on the fixed seats, and L-shaped rotating blocks are rotatably installed on the mounting shafts. Matching clamps are slidably connected in the guide cylinders. The front end of the telescopic rod provided at the output end of the cylinder is rotatably connected to one end of the rotating block, and the inner end of the matching clamp is rotatably connected to the other end of the rotating block. The outer ends of the four matching clamps extend outward from the side walls of the fixture box, and fixed clamps adapted to the four matching clamps are fixedly provided on the outer walls of the fixture box. A single matching clamp and the fixed clamp form a clamp assembly and achieve clamping.

[0006] In a better technical solution, a conveying platform and a slide are respectively provided on the left and right sides of the fixture box. The conveying platform is tilted downward and is used to slide the metal shafts arranged in sequence. The thread rolling machine body is slidably connected to the slide, and the thread rolling machine body moves in the direction close to or away from the fixture box.

[0007] In a preferred technical solution, mounting brackets are respectively provided at both ends of the fixture box, and the fixture box is rotatably connected between the two mounting brackets via a rotating shaft.

[0008] In a preferred technical solution, a motor for driving the fixture box to rotate is provided on one of the mounting frames, the fixture box is suspended, and a receiving box is placed at the bottom of the fixture box.

[0009] In a preferred technical solution, the two fixing seats, mounting shafts and guide cylinders on the same end wall of the fixture box maintain a centrally symmetrical relationship, and the fixing seats, mounting shafts and guide cylinders on the two end walls of the fixture box remain aligned.

[0010] In a preferred technical solution, a through opening is provided on the side wall of the fixture box for the mating clamp to extend outward.

[0011] In a preferred technical solution, the fixed clamping block and the matching clamping block of the clamping block assembly are relatively staggered in position.

[0012] The beneficial effects of the utility model are:

[0013] The fixture box proposed in this solution solves the problem of batch long shaft thread rolling processing. Since the long shaft needs to be replaced manually, the thread rolling process is inefficient. The rotating fixture box has two sets of clamping block assemblies that cooperate to clamp the long shaft, which can realize long shaft thread rolling and long shaft clamping and release at the same time. The clamping block assemblies on both sides work together to ensure continuous thread rolling processing of the long shaft, and the automated working mode greatly improves work efficiency.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In this embodiment, refer to the attached Figure 1The thread rolling machine thread processing fixture includes a fixture box 1. The fixture box 1 is a hollow cylindrical structure with mounting brackets 2 at each end. The fixture box 1 is rotatably connected between the two mounting brackets 2 via a rotating shaft. One of the mounting brackets 2 is equipped with a motor 15 that drives the fixture box 1. The fixture box 1 is suspended in the air, and a receiving box is placed at the bottom of the fixture box 1. The motor 15 can drive the fixture box 1 to rotate, and the receiving box at the bottom is used to receive the processed workpiece.

[0020] As attached Figure 1 As shown, a conveyor platform 3 and a slide 5 are respectively provided on the left and right sides of the fixture box 1. The conveyor platform 3 is tilted downward and is used to slide metal shafts 4 arranged in sequence. The metal shafts 4 automatically slide down to the lowest point under gravity, and are then gripped and removed one by one by the fixture box 1. A thread rolling machine body 6 is slidably connected to the slide 5, and the thread rolling machine body 6 moves along the surface of the slide 5 toward or away from the fixture box 1.

[0021] Refer to the attached Figure 2 The inner walls at both ends of the fixture box 1 are respectively provided with two fixing seats 7, mounting shafts 9 and guide cylinders 11, and the fixing seats 7 are rotatably mounted with cylinders 8. Figure 2 It can be seen that the two fixing seats 7, mounting shafts 9 and guide cylinders 11 on the same end wall of the fixture box 1 maintain a centrally symmetrical relationship, and the positions of the fixing seats 7, mounting shafts 9 and guide cylinders 11 on the two end walls of the fixture box 1 remain aligned.

[0022] An L-shaped rotating block 10 is rotatably installed on the mounting shaft 9, and a matching clamping block 12 is slidably connected in the guide cylinder 11. The front end of the telescopic rod arranged at the output end of the cylinder 8 is rotatably connected to one end of the rotating block 10, and the inner end of the matching clamping block 12 is rotatably connected to the other end of the rotating block 10. The outer ends of the four matching clamping blocks 12 extend outward from the side wall of the fixture box 1. Accordingly, a through opening 13 for the matching clamping blocks 12 to extend outward is also opened on the side wall of the fixture box 1.

[0023] A fixed clamping block 14 adapted to the four matching clamping blocks 12 is fixedly provided on the outer wall of the clamp box 1. A single matching clamping block 12 and a fixed clamping block 14 form a clamping block assembly and achieve clamping. Figure 3 It can be seen that the fixed clamping block 14 and the matching clamping block 12 of the clamping block assembly are relatively staggered. Maintaining the staggered fixed clamping block 14 and the matching clamping block 12 can provide stability for clamping the metal shaft 4.

[0024] Specific working principle: Combined with the attached Figure 2To explain, as the fixture box 1 rotates, the two mating clamps 12 on the left side retract into the fixture box 1, and the two fixed clamps 14 can be used to lift the metal shaft 4 at the bottom layer of the conveying platform 3, so that the metal shaft 4 is separated from the conveying platform 3; the fixture box 1 continues to rotate, and the cylinder 8 on the left side of the fixture box 1 is started at this time, and the cylinder 8 is used to push the corresponding rotating block 10 and push the mating clamp 12 outward along the guide cylinder 11. Therefore, the mating clamp 12 can contact the two sides of the metal shaft 4 with the fixed clamp 14 respectively and achieve clamping; when the fixture box 1 rotates 180° to the right, the thread rolling machine body 6 on the slide 5 is gradually pushed to the left, and the thread rolling wheel can be used to process the metal shaft 4; after the processing is completed, the fixture box 1 continues to rotate, and the cylinder 8 retracts at the same time, and the metal shaft 4 is free from the restriction of the clamp assembly and can fall freely into the receiving box below for recycling.

[0025] The above process is the entire process of clamping, rolling and releasing on the left half, and the operation process of the right half of the fixture box 1 is the same. When one side is rolling, the other side can be used to clamp the metal shaft 4. Both sides are carried out at the same time, so in batch long shaft rolling operations, work efficiency can be greatly improved.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
