[0002] During the processing and assembly of cylindrical workpieces, the centering device is a key equipment in the processing and assembly process, which is used to realize the rapid centering and clamping of cylindrical workpieces. The three-jaw chuck is a relatively common centering device at this stage, and is widely used in the field of parts processing. The key components of the three-jaw chuck are the bevel gear and flat thread rotation mechanism. By rotating the chuck wrench, the three chuck jaws will move synchronously inward or outward along the radial direction, thereby realizing the clamping or loosening of the workpiece. However, for some circular workpieces, such as the workpiece itself The material is easy to break, the volume is large, and the weight is heavy.

[0003] Under the existing technology, when steel bars are produced and processed, many processes (such as grinding and deburring) require the steel bars to be flipped to complete the processing of the other side of the steel bars. The existing centering device makes it difficult to achieve controllable clamping force, and it is difficult to achieve clamping of larger diameter workpieces such as cylindrical workpieces. At the same time, the steel bar is locked when it is fixed and cannot be rotated. When the steel bar needs to be flipped, the limit on the steel bar needs to be cancelled. When the steel bar is flipped, it is easy to cause the steel bar to shift, affecting the production quality, while increasing the workload of the staff and reducing production efficiency.

[0004] Therefore, it is particularly important to design a new type of centering device for steel bar production to solve the above technical defects and improve the practicability of the centering device for steel bar production as a whole. Utility Model Content

[0023] Example:

[0024] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0025] A centering device for steel bar production comprises a base 1, a positioning assembly 3 is connected to the top of the base 1 through a movable column 2, and a clamping plate 4 is provided on the top of the base 1 and located on the front of the positioning assembly 3;

[0026] Among them, a connecting seat 101 is fixedly connected to the top of the base 1 and at a position corresponding to the moving column 2, a moving motor 102 is installed on the front of the connecting seat 101 and at a position corresponding to the moving column 2, and a sliding column 103 is fixedly connected between the connecting seat 101 and the positioning assembly 3.

[0027] Specifically, first, the base 1 is placed at the specified position, and the head of the steel rod to be processed is placed in the positioning component 3, and the tail end of the steel rod is placed in the clamping plate 4. The head and tail ends of the steel rod are clamped and fixed by the positioning component 3 and the clamping plate 4 respectively. At this time, the moving column 2 is driven to rotate by the moving motor 102, and then the moving column 2 is rotated in the connecting seat 101 and the positioning component 3, and then the clamping plate 4 is driven to move on the base 1, so that the end of the steel rod can be clamped and fixed.

[0028] Also, see Figure 1 and Figure 2 , the top of the base 1 is connected with a positioning assembly 3 through a movable column 2;

[0029] The positioning assembly 3 is used to clamp and fix the head of the steel rod. The specific structure of the positioning assembly 3 is as follows:

[0030] The positioning assembly 3 includes a positioning seat 301, a support ring 302, a lifting cylinder 303, a positioning plate 304, a stabilizing column 305 and an anti-slip pad 306. The top of the positioning seat 301 is fixedly connected to the support ring 302, the top of the support ring 302 is installed with a lifting cylinder 303, the lifting cylinder 303 penetrates the support ring 302 and is fixedly connected to the positioning plate 304, the top of the positioning plate 304 and the left and right sides of the lifting cylinder 303 are fixedly connected with stabilizing columns 305, the inner side of the positioning plate 304 is fixedly connected with a number of anti-slip pads 306 made of rubber, and the two groups of stabilizing columns 305 are connected to the support ring 302 by sliding connection.

[0031] Specifically, the head of the steel rod is clamped and fixed by the positioning component 3, and the head of the steel rod is placed in the positioning seat 301. A V-shaped groove is provided inside the positioning seat 301. At this time, the support ring 302 supports the lifting cylinder 303, and the lifting cylinder 303 drives the positioning plate 304 to move, so that the positioning plate 304 moves up and down in the support ring 302 through the stabilizing column 305, and then the steel rod in the positioning seat 301 is clamped and fixed by the positioning plate 304, and the anti-slip pad 306 improves the clamping effect of the positioning plate 304 on the steel rod.

[0032] Then, see Figure 1 and Figure 3 A clamping plate 4 is provided on the top of the base 1 and on the front of the positioning assembly 3;

[0033] The clamping plate 4 is used to clamp and fix the tail of the steel rod. The specific structure of the clamping plate 4 is as follows:

[0034] A telescopic seat 401 is fixedly connected to the front of the clamping plate 4 and located at a position corresponding to the positioning component 3. A telescopic column 402 is arranged inside the telescopic seat 401. A clamping seat 403 is arranged on the front of the clamping plate 4 and located at a position corresponding to the telescopic column 402. A roller groove 404 is opened inside the clamping seat 403. A plurality of rollers 405 are rotatably connected inside the roller groove 404. A clamping motor 406 is arranged on the front of the clamping seat 403 and located at a position corresponding to one group of rollers 405. The plurality of rollers 405 The outside of each is sleeved with three groups of anti-skid rings 407 made of rubber, the telescopic column 402 passes through the clamping plate 4 and is rotatably connected to the clamping seat 403, the interior of the clamping seat 403 and is fixedly connected to a limiting column at a position corresponding to the clamping motor 406, the limiting column passes through the clamping seat 403 and extends to the inside of the roller groove 404, the contact surface between the limiting column and the roller 405 is fixedly connected with an anti-skid pad made of rubber, and the connection between the clamping motor 406 and the clamping seat 403 is a threaded connection.

[0035] Specifically, the tail of the steel rod is clamped by the clamping plate 4, and the telescopic seat 401 drives the telescopic column 402 to move, and then the telescopic column 402 drives the clamping seat 403 to move, and the steel rod is clamped by the clamping seat 403. The anti-skid ring 407 on the outside of the roller 405 increases the friction between the roller 405 and the steel rod, which has an anti-skid effect on the steel rod and prevents the steel rod from loosening during installation. When the user needs to rotate the steel rod during installation, the clamping motor 406 is rotated, and the clamping motor 406 drives the limit column to rotate, and the squeezing force of the limit column on the roller 405 is released, so that the limit on the roller 405 can be cancelled, so that the roller 405 can rotate in the roller groove 404 in the clamping seat 403.

Compared with the existing centering device for steel rod production, the utility model can improve the overall practicality of the centering device for steel rod production through design.
