Description

Technical Field

[0001] The utility model relates to the technical field of positioning fixtures, in particular to a positioning fixture for ring die processing. Background Art

[0002] Ring die is mainly used in feed processing. The feed is extruded through the ring die, and then the short pellet feed is cut by a cutter. It has the characteristics of small footprint, low noise and wide range of use. Therefore, it is widely used in aquaculture farms, feed processing plants and poultry farms. Now, in the process of ring die processing, such as grinding, polishing or cutting, the ring die needs to be clamped and positioned, so a clamp is needed to work.

[0003] The existing clamps are generally clamped by the rebound effect of the spring during operation. When the clamping state is maintained for a long time, the stretched length of the spring is at a constant value. The elastic force of the spring will cause a certain loss during use, thereby causing clamping obstacles and affecting the positioning effect of the ring die processing. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a positioning fixture for ring die processing, which is used in combination of a mounting plate, a slot, a clamping plate, a bracket, a driving motor, a rotating rod, a rotating plate and a hinged rod. By turning on the driving motor, the two clamping plates and the two mounting plates can be automatically and synchronously driven to move toward or away from each other. When the clamping plates move away from each other, the inner wall of the ring die can be clamped against it, thereby limiting the problem of the ring die falling off during processing, and can enhance the clamping efficiency of the ring die. Under long-term clamping work, the fixture can also be used well, meeting the use requirements and other advantages, solving the problems raised by the background technology.

[0026] Example

[0027] Reference Figure 1-4 As shown, a positioning fixture for ring die processing includes a positioning table 1, a plurality of support columns 2 fixed to the bottom of the positioning table 1, and a ring die 3 placed on the top of the positioning table 1. Two sets of mounting plates 411 are slidably connected inside the positioning table 1. A slot 412 is provided at the top of the positioning table 1. The mounting plate 411 is slidably connected to the inner wall of the slot 412. A sliding block 419 is provided on the inner wall of the slot 412. A sliding groove 420 corresponding to the sliding block 419 is fixed on the outer wall of the mounting plate 411. This method makes the sliding of the mounting plate 411 more stable and can also prevent the mounting plate 411 from falling off. A clamping plate 413 corresponding to the ring die 3 is installed on the side away from the two sets of mounting plates 411. The clamping plate 413 is "L" shaped and can be sleeved on the outer wall of the ring die 3 to prevent the ring die 3 from falling off. The clamping plate 413 can be made of hard leather material, which has good wear resistance. The clamping plate 413 can clamp and resist the inner wall of the ring die 3, so as to prevent the ring die 3 from falling off or shaking during processing of the ring die 3, and achieve good stability. A driving component for driving the two sets of slots 412 to move toward or away from each other is provided at the top of the positioning table 1. The driving component can be used to synchronously push the installation plate 411 and the clamping plate 413 to move, so as to achieve a stable pushing effect.

[0028] The driving components include a bracket 414, a driving motor 415, a rotating rod 416, a rotating plate 417 and a hinged rod 418. The bracket 414 is fixed to the bottom end of the mounting plate 411. The driving motor 415 is installed in the middle position of the top of the positioning table 1 and the output end is connected to the rotating rod 416. The rotating plate 417 is fixed to the end of the rotating rod 416 away from the driving motor 415. Both ends of the rotating plate 417 are respectively hinged to the bottom of the bracket 414 through the hinged rod 418. By turning on the driving motor 415, the rotating rod 416 and the rotating plate 417 are driven to rotate. The two ends of the rotating plate 417 respectively drive the hinged rod 418 to rotate, and push the bracket 414 and the mounting plate 411 to move horizontally, so that the mounting plates 411 and the slots 412 on the left and right sides can move toward or away from each other synchronously, so as to achieve an automated driving effect, enhance the clamping effect of the equipment, and improve the clamping stability of the ring mold 3.

[0029] The outer wall of the clamping plate 413 is fixed with an insert block 512, and the inner wall of the mounting plate 411 is provided with a hole 511 corresponding to the insert block 512. The insert block 512 is passed through the hole 511 to preliminarily lock the clamping plate 413, thereby achieving a fixing effect. The mounting plate 411 is slidably connected with a movable plate 513 on a side away from the clamping plate 413. The movable plate 513 can be moved up and down to be inserted into the insert block 512. By pulling the movable plate 513 upward, the movable plate 513 can be embedded in the insert block 512, thereby ensuring that the insert block 512 will not be separated from the hole 511, thereby achieving an installation effect. The outer wall of the movable plate 513 is fixed with a movable block 515, and the outer wall of the mounting plate 411 is provided with a groove 514 that slidably cooperates with the movable block 515. The movable plate 513 can stably slide back and forth vertically under the action of the movable block 515 and the groove 514, thereby achieving a good moving effect. A spring 516 is arranged inside the groove 514, one end of the spring 516 is connected to the movable plate 513, and the other end is connected to the inner wall of the groove 514. The spring 516 is arranged to achieve a better elastic effect. In the initial state, the spring 516 can drive the movable block 515 to rise, and push the movable plate 513 to be inserted into the insert block 512, so as to achieve a locking effect, thereby improving the replacement efficiency of the clamping plate 413 and the mounting plate 411 and meeting the use requirements of the device.

[0030] Working principle: When it is needed, the ring die 3 is placed on the positioning table 1 and the ring die 3 is coaxially distributed with the positioning table 1. The driving motor 415 is turned on to drive the rotating rod 416 and the rotating plate 417 to rotate. The two ends of the rotating plate 417 respectively drive the hinge rod 418 to rotate, and push the mounting plate 411 to slide inside the slot 412, so that the two groups of mounting plates 411 and the two groups of clamping plates 413 move away from each other, clamp the inner wall of the ring die 3 and position it to achieve a reinforcement effect.

[0031] When the clamping plate 413 needs to be replaced, the movable plate 513 is pulled downward to make the movable block 515 slide downward in the groove 514, causing the spring 516 to be squeezed and compressed, and the movable plate 513 is separated from the bottom end of the plug block 512. At this time, the plug block 512 will not be interfered with, and the clamping plate 413 can be easily replaced by pulling it outward.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
