Description
Technical Field
[0001] This utility model relates to the field of screw mold processing technology, specifically a clamping fixture for screw mold processing that provides secure clamping. Background Technology
[0002] Fixtures for screw mold processing are tools used to fix and support workpieces during screw mold production. Their main function is to ensure the precise positioning and stability of the mold during processing, thereby improving machining accuracy and production efficiency. Fixture design typically takes into account the size, shape, and machining requirements of the screw mold to ensure fast and accurate machining operations. Through reasonable fixture design, machining errors can be effectively reduced and the level of production automation can be improved.
[0003] A clamping fixture for machining screw molds, disclosed in Chinese Patent Publication No. CN107627117A, effectively clamps the workpiece by using a first fixed plate, a second fixed plate, and a movable plate in combination, making it less prone to loosening. The presence of a pressure sensor allows for effective response to the actual clamping force acting on the workpiece, facilitating adjustment of the clamping force. The scale bar facilitates workpiece positioning during machining. The reinforcing plate prevents the first and second fixed plates from deforming. However, the fixture has limited functionality; after clamping and machining the mold, it is not convenient to quickly remove the mold, affecting the overall ease of use and flexibility of the fixture. Utility Model Content
[0004] The purpose of this utility model is to provide a clamping fixture for screw mold processing that provides a secure gripping mechanism, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for processing screw molds with a firm gripping mechanism, comprising a base, a clamping mechanism disposed at the middle position of the bottom end of the base, connecting rods disposed on both sides of the top end of the clamping mechanism, a clamping member sleeved on the outside of the top end of the connecting rods, an installation mechanism disposed on one side inside the clamping member, a mold body disposed at the middle position of the top end of the base, a material layer disposed inside the clamping member, a lifting mechanism disposed at the top end of the clamping mechanism, and a push plate disposed at the top end of the lifting mechanism.
[0006] Preferably, the clamping mechanism includes a servo motor installed at the middle position of the bottom of the base, a gear installed at the output shaft end of the servo motor, a rack with its top end fixedly connected to a connecting rod meshing on both sides of the gear, and a sliding block fixedly connected to one side of the rack.
[0007] Preferably, a limiting block is fixedly connected to one side of the clamping member, and limiting grooves that engage with the limiting block are provided on both sides of the outside of the mold body.
[0008] Preferably, the installation mechanism includes a threaded groove at the top of one side of the connecting rod, a rotating rod rotatably connected to one side of the clamping member, a movable disc fixedly connected to one side of the rotating rod, and a bolt threadedly connected to the threaded groove fixedly connected to the middle position of one side of the movable disc.
[0009] Preferably, the material layer includes a damping layer disposed inside the clamping member, the damping layer being made of manganese-copper alloy, a toughness layer disposed outside the damping layer, the toughness layer being made of high-strength alloy steel, a wear-resistant layer disposed outside the toughness layer, and a ceramic matrix composite material disposed outside the wear-resistant layer.
[0010] Preferably, the lifting mechanism includes a threaded rod fixedly connected to the top of a gear, and the threaded rod is externally threaded to a threaded cylinder whose top end is fixedly connected to a push plate. The bottom ends of both sides of the threaded cylinder are fixedly connected to limiting rods that are slidably connected within the platform.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This type of clamping fixture for machining screw molds with a firm gripping mechanism is provided at the bottom of the base. When the servo motor on the clamping mechanism is started, it can drive the gear to rotate. At this time, the gear can push the racks on both sides to move, and the racks can drive the clamping parts to perform stable clamping work on the mold body through the connecting rod. At the same time, the top of the gear is provided with a threaded rod that can rotate in the threaded cylinder. When the clamping parts release the clamping of the mold body, the threaded cylinder can push the mold body to lift quickly through the push plate, thereby realizing the rapid lifting and unloading of the mold body. This improves the clamping stability of the fixture, while also improving the overall functionality and ease of use of the fixture.
[0013] 2. This type of clamping fixture for machining screw molds features an installation mechanism inside the clamping component. The clamping component is installed on the top of the connecting rod by turning a bolt into a threaded groove on the connecting rod. When the bolt is pulled out of the threaded groove, the clamping component can be removed from the top of the connecting rod, allowing for quick replacement of the clamping component according to the actual mold specifications. The clamping component incorporates a damping layer, a toughening layer, and a wear-resistant layer. It utilizes novel materials such as manganese-copper alloy and alloy steel ceramic matrix composites, combining the advantages of different materials to improve the fixture's wear resistance, shock absorption, and service life, thus extending the overall service life of the fixture.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-5 This utility model provides two technical solutions:
[0022] Example 1: A clamping fixture for processing screw molds with secure clamping includes a base 1. A clamping mechanism 2 is provided at the middle position of the bottom of the base 1. Connecting rods 3 are provided on both sides of the top of the clamping mechanism 2. A clamping member 4 is sleeved on the outside of the top of the connecting rods 3. An installation mechanism 5 is provided on one side inside the clamping member 4. A mold body 6 is provided at the middle position of the top of the base 1. A material layer 7 is provided inside the clamping member 4. A lifting mechanism 8 is provided at the top of the clamping mechanism 2. A push plate 9 is provided at the top of the lifting mechanism 8.
[0023] The clamping mechanism 2 includes a servo motor 201 installed at the middle of the bottom of the base 1. A gear 202 is installed at the output shaft end of the servo motor 201. A rack 203 with its top fixedly connected to the connecting rod 3 is meshed on both sides of the gear 202. A sliding block 204 is fixedly connected to one side of the rack 203. When the servo motor 201 is started, it can drive the gear 202 to rotate. At this time, the gear 202 pushes the racks 203 on both sides to move, so that the racks 203 can drive the clamping member 4 through the connecting rod 3 to complete the clamping work of the mold body 6.
[0024] A limiting block 401 is fixedly connected to one side of the clamping member 4. Limiting grooves 601 that engage with the limiting block 401 are provided on both sides of the outside of the mold body 6. The insertion of the limiting block 401 on the clamping member 4 into the limiting groove 601 on the mold body 6 can increase the stability of the clamping member 4 in clamping the mold body 6.
[0025] The lifting mechanism 8 includes a threaded rod 801 fixedly connected to the top of the gear 202. The threaded rod 801 is externally threaded to a threaded cylinder 802 fixedly connected to the top of the push plate 9. Limiting rods 803 that slide within the platform 1 are fixedly connected to the bottom ends of both sides of the threaded cylinder 802. When the gear 202 rotates, it can synchronously drive the threaded rod 801 to rotate within the threaded cylinder 802. At this time, the threaded cylinder 802 can push the push plate 9 to perform lifting and lowering movements, and push the mold body 6 at the top to perform lifting work.
[0026] Example 2 differs from Example 1 mainly in that:
[0027] A clamping fixture for machining screw molds with a secure gripping mechanism 5 includes a threaded groove 301 at the top of one side of a connecting rod 3. A rotating rod 501 is rotatably connected to one side of the clamping member 4. A movable disk 502 is fixedly connected to one side of the rotating rod 501. A bolt 503, which is threadedly connected to the threaded groove 301, is fixedly connected to the middle position of one side of the movable disk 502. By rotating the rotating rod 501 on the clamping member 4, the rotating rod 501 can drive the bolt 503 to rotate through the movable disk 502. When the bolt 503 rotates into the threaded groove 301 on the connecting rod 3, the installation of the clamping member 4 on the outside of the connecting rod 3 can be completed.
[0028] Material layer 7 includes a damping layer 701 inside the clamping member 4. The damping layer 701 is made of manganese copper alloy, which has excellent vibration reduction and noise reduction performance, effectively absorbs the vibration generated during the processing, and improves the processing accuracy and surface quality.
[0029] The damping layer 701 is surrounded by a toughness layer 702. The toughness layer 702 is made of high-strength alloy steel, which provides sufficient support to resist deformation and vibration during processing, ensure processing stability, and effectively absorb impact energy to prevent the fixture from cracking or breaking, thereby improving safety.
[0030] The toughness layer 702 is surrounded by a wear-resistant layer 703, which is surrounded by a ceramic matrix composite material. This significantly improves the surface hardness of the fixture, resists wear during processing, extends service life, reduces the coefficient of friction, reduces heat accumulation, and improves processing accuracy and surface finish. In addition, all contents not described in detail in this specification are prior art known to those skilled in the art.
[0031] In this embodiment, the mold body 6 to be processed is placed at the middle position of the top of the platform 1. At this time, the servo motor 201 inside the platform 1 starts and drives the gear 202 to rotate. The gear 202 can push the racks 203 on both sides to move, and the racks 203 can drive the clamping parts 4 to move through the connecting rod 3. At this time, the two sets of clamping parts 4 at the top of the platform 1 can complete the clamping work of the mold body 6. At the same time, the limiting block 401 on the clamping part 4 can be inserted into the limiting groove 601 on the mold body 6. After the mold body 6 is processed, the servo motor 201 drives the gear 202 to reverse, and the gear 202 pushes the rack 203 to move in the opposite direction. Through the connecting rod 3, the clamping parts 4 are driven to leave the outer surface of the mold body 6. At the same time, the gear 202 drives the threaded rod 801 to rotate inside the threaded cylinder 802, which can push the push plate 9 to lift, thereby pushing the mold body 6 to lift and discharge quickly.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
