Description

Technical Field

[0001] This utility model relates to the field of roller processing technology, and in particular to a positioning fixture for roller processing. Background Technology

[0002] A roller is a cylindrical, rotatable object in machinery. Rollers are often driven by a power source to propel other materials forward or to generate pressure for processing. Existing rollers require positioning during welding or other processing. Chinese utility model patent CN221538593U discloses a roller welding positioning fixture. This fixture uses an arc-shaped clamping seat to hold the roller horizontally and an arc-shaped pressing seat and placement seat to press the roller vertically, thus fixing and positioning the roller to be welded. However, this solution has the following drawbacks: it can only position one roller at a time, resulting in low work efficiency; the arc-shaped clamping seat cannot be adjusted in height; the distance between the two U-shaped frames is fixed, preventing perfect adaptation to rollers of different specifications and limiting its applicability. Summary of the Invention

The first groove and the first cavity are connected, and the first slider is slidably disposed in the first groove and the first cavity.

[0009] Specifically, the first power mechanism includes a rotating shaft rotatably connected in the first cavity, a first motor mounted on one side of the base to drive the rotating shaft to rotate, the rotating shaft being provided with several positive and negative threaded screws, and a pair of first sliders at the bottom of the clamping seats being threadedly connected to the positive and negative threaded screws to achieve mutual approach or distance.

[0016] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figures 1-2 As shown, a roller processing positioning fixture includes a base frame 1, with several slide rails 2 on the top of the base frame 1. Bases 3 are slidably mounted at the front and rear ends of the top of the slide rails 2. A fixing mechanism is provided between the bases 3 and the slide rails 2. Several slide blocks 12 corresponding to the slide rails 2 are provided at the bottom of the bases 3. The slide blocks 12 are slidably mounted on the slide rails 2. The fixing mechanism includes fixing bolts 13 passing through the front and rear sides of the slide blocks 12 and several threaded holes 14 provided on the slide rails 2. The slide blocks 12 are fixed by screwing the fixing bolts 13 into the threaded holes 14. The distance between the two bases 3 is adjustable, facilitating adjustment according to rollers 10 of different lengths, providing high flexibility.

[0019] The base 3 has an inverted U-shaped mounting bracket 4 on its top. Several pairs of relatively sliding clamping seats 5 are provided between the opposite surfaces of the base 3 and the mounting bracket 4. The base 3 has a first power mechanism that drives the several pairs of clamping seats 5 to slide. The base 3 has a first cavity 15 inside. The clamping seats 5 have a first slider 16 at their bottom. The base 3 has a first groove corresponding to the first slider 16 at its top. The first groove and the first cavity 15 are connected. The first slider 16 is slidably disposed in the first groove and the first cavity 15. The first power mechanism includes a rotating shaft 17 rotatably connected in the first cavity 15 and a first motor 18 installed on one side of the base 3 to drive the rotating shaft 17 to rotate. The rotating shaft 17 has several positive and negative threaded screw threads 19. The first sliders 16 at the bottom of a pair of clamping seats 5 are respectively threaded onto the positive and negative threaded screw threads 19 to achieve mutual approach or distance. By starting the first motor 18 to rotate in both directions, a pair of clamping seats 5 can be controlled to clamp or release the roller 10; by setting several positive and negative threaded screws 19 on the rotating shaft 17, multiple pairs of clamping seats 5 can be controlled to work synchronously, resulting in high work efficiency.

[0020] The base 3 has several support blocks 6 on its top, located between a pair of clamping seats 5. Each clamping seat 5 has a sliding clamping block 7 on its side near the support blocks 6, and a second power mechanism on the clamping seat 5 to drive the clamping block 7 to slide. The clamping seat 5 has a second cavity 20 inside, and a second slider 21 on the side of the clamping block 7 near the clamping seat 5. The clamping seat 5 has a second groove corresponding to the second slider 21, which communicates with the second cavity 20. The second slider 21 slides within the second groove and the second cavity 20. The second power mechanism includes a lead screw 22 rotatably connected within the second cavity 20 and a second motor 23 mounted on one side of the clamping seat 5 to drive the lead screw 22 to rotate. The second slider 21 and the lead screw 22 are threadedly connected. By setting the height-adjustable clamping block 7, it is convenient to adjust it according to rollers 10 of different diameters, ensuring that the clamping block 7 is aligned with the center of the side wall of the roller 10, thus guaranteeing positioning stability.

[0021] The top of the mounting frame 4 is equipped with several electric cylinders 8 corresponding to the support blocks 6. The telescopic rods of the electric cylinders 8 pass through the mounting frame 4 and are fixedly connected to the pressure blocks 9. The roller 10 to be processed is supported at the bottom by the support blocks 6, and the clamping blocks 7 clamp the side walls and the pressure blocks 9 press the top to fix it. The support blocks 6, clamping blocks 7, and pressure blocks 9 are all equipped with rubber anti-slip blocks 11 on the side facing the roller 10. The rubber material has a high coefficient of friction, which can effectively prevent the roller 10 from sliding in the rubber anti-slip blocks 11, ensuring that the roller 10 remains stable during processing or assembly. The rubber has good elasticity and can adapt to rollers 10 of different diameters. When the rubber anti-slip blocks 11 clamp the roller 10, the rubber anti-slip blocks 11 can automatically adjust their shape and fit tightly against the surface of the roller 10, thereby improving the stability and reliability of clamping.

[0022] When this utility model is in operation, the position of the base 3 on the slide rail 2 and the position of the clamping block 7 on the clamping seat 5 are adjusted according to the specifications of the roller 10 to be processed. Then, the roller 10 is placed on the support block 6, the first motor 18 is started, the clamping block 7 clamps the two sides of the roller 10, the electric cylinder 8 is started, and the pressure block 9 presses the top of the roller 10 to achieve the positioning and fixing of the roller 10.

[0023] This invention can simultaneously position multiple rollers 10, resulting in high working efficiency. It is also easy to adapt to rollers 10 of different specifications, has a wide range of applications, and is convenient to use.
