Description

Technical Field

[0001] This utility model relates to the field of meat grinder processing, and in particular to a clamping fixture for preventing the rotation of the spiral shaft of a meat grinder. Background Technology

[0002] Meat grinders are used by meat processing companies to process raw meat into granular minced meat of varying sizes according to different process requirements. They are widely used in various industries such as sausages, ham sausages, luncheon meat, meatballs, savory flavorings, pet food, and other meat products.

[0003] During the production process of a meat grinder, the twisting end of the meat grinder's spiral shaft needs to be processed. Existing clamping devices cannot adapt to the complex structure of the spiral shaft and are not convenient for clamping the spiral shaft at the spiral blade end. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art by designing a machining clamping fixture for preventing the rotation of the spiral shaft of a meat grinder.

[0005] The technical solution of this utility model to achieve the above objectives is as follows: a clamping fixture for anti-rotation processing of a meat grinder's spiral shaft, comprising a mounting frame, a telescopic assembly, a clamping plate, a polygonal rod, an expansion and contraction assembly, a limiting groove, and a spiral shaft body. Two telescopic assemblies are slidably inserted into the upper part of the mounting frame. A clamping plate is provided at the front end of each telescopic assembly. A polygonal rod is installed on the outer side of the clamping plate. The polygonal rod is slidably inserted into the front end of the telescopic assembly. An expansion and contraction assembly is connected to the outer end of the polygonal rod. The expansion and contraction assembly is mounted on the mounting frame, and its two ends are slidably connected to the outer end of the polygonal rod. The expansion and contraction assembly drives the polygonal rod to move inward or outward through expansion and contraction. A limiting groove is opened in the middle of the front part of the mounting frame. The shape of the limiting groove corresponds to the shape of the non-twisting end of the spiral shaft body.

[0006] Furthermore, the telescopic assembly includes a sliding frame and a telescopic cylinder. The sliding frame is slidably inserted into the mounting frame, and the front end of the sliding frame is slidably penetrated by a polygonal rod. The telescopic cylinder is connected to the sliding frame, and the cylinder body of the telescopic cylinder is fixedly installed on the mounting frame.

[0007] Furthermore, the expansion and contraction assembly includes a guide block, a sliding rod, a connecting block, a lifting cylinder, and a connecting rod. A guide block is installed at the outer end of the polygonal rod, and a sliding rod is slidably inserted into the guide block. A connecting block is fixedly connected to the rear end of the sliding rod. The lower inner side of the connecting block is slidably inserted into the mounting frame and is staggered from the sliding frame. A lifting cylinder is installed at the upper end of the mounting frame. Connecting rods are rotatably installed on both sides of the telescopic end of the lifting cylinder. The outer ends of the connecting rods are rotatably connected to the connecting blocks on both sides.

[0008] Furthermore, the lower inner side of the connecting block is provided with a plate-like structure, and the connecting block is slidably inserted into the mounting frame through the plate-like structure and intersects with the sliding frame.

[0009] Furthermore, the clamp is a plate-like structure with an arc-shaped inner surface.

[0010] Beneficial effects:

[0011] This utility model provides a clamping fixture for preventing the rotation of a meat grinder's spiral shaft. It offers the following advantages: Through its structural design, the non-rotating end of the spiral shaft is inserted into a limiting groove. Then, an expansion and contraction assembly drives a polygonal rod to move inward. This inward movement of the polygonal rod causes a clamping plate to clamp the gap between the spiral plates of the spiral shaft. Next, a telescopic assembly moves the polygonal rod and clamping plate backward, causing the clamping plate to pull the spiral shaft backward, thus limiting its rotation in the front-to-back direction. The limiting groove effectively limits the rotation of the spiral shaft, thereby limiting the non-rotating end of the spiral shaft. Attached Figure Description

[0020] Please see Figure 1-4 This utility model provides a technical solution: a clamping fixture for preventing rotation of a meat grinder's spiral shaft, comprising a mounting frame 1, a telescopic assembly, a clamping plate 2, a polygonal rod 3, an expansion and contraction assembly, a limiting groove 4, and a spiral shaft body 5. Two telescopic assemblies are slidably inserted into the upper part of the mounting frame 1.

A limiting groove 4 is opened in the middle of the front part of the mounting frame 1, and the shape of the limiting groove 4 corresponds to the shape of the non-twisting end of the spiral shaft body 5.

[0021] In this utility model, the telescopic component includes a sliding frame 6 and a telescopic cylinder 7. The sliding frame 6 is slidably inserted into the mounting frame 1. The front end of the sliding frame 6 is slidably penetrated by a polygonal rod 3. The telescopic cylinder 7 is connected to the sliding frame 6. The cylinder body of the telescopic cylinder 7 is fixedly installed on the mounting frame 1. The two telescopic cylinders 7 drive the two sliding frames 6 to move respectively, thereby realizing the telescopic action.

[0022] In this utility model, the expansion and contraction assembly includes a guide block 8, a sliding rod 9, a connecting block 10, a lifting cylinder 11, and a connecting rod 12. The outer end of the polygonal rod 3 is equipped with a guide block 8, and a sliding rod 9 is slidably inserted into the guide block 8. The rear end of the sliding rod 9 is fixedly connected to the connecting block 10. The lower inner side of the connecting block 10 is slidably inserted into the mounting frame 1 and is staggered from the sliding frame 6. The upper end of the mounting frame 1 is equipped with a lifting cylinder 11. Connecting rods 12 are rotatably installed on both sides of the telescopic end of the lifting cylinder 11. The outer ends of the connecting rods 12 are rotatably connected to the connecting blocks 10 on both sides. The lifting cylinder 11 drives the connecting rods 12 to move, which in turn drives the guide block 8 to contract inward or expand outward, thereby driving the sliding rod 9 to drive the guide block 8 to move, and further driving the polygonal rod 3 to move.

[0026] In this implementation plan:

[0027] In use, the non-twisting end of the spiral shaft body 5 is inserted into the limiting groove 4. Then, the expansion and contraction assembly drives the polygonal rod 3 to move inward. The inward movement of the polygonal rod 3 causes the clamping plate 2 to clamp the gap between the spiral plates of the spiral shaft body 5. Then, the telescopic assembly moves the polygonal rod 3 and the clamping plate 2 backward, thereby causing the clamping plate 2 to pull the spiral shaft body 5 backward, limiting the spiral shaft body 5 in the front and back directions. The limiting groove 4 achieves rotational limitation of the spiral shaft body 5, thereby limiting the non-twisting end of the spiral shaft body 5.
