Description

Technical Field

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

[0002] Fixtures for machining parts are auxiliary tools or devices used in the machining process to correctly, quickly, and reliably position and clamp the workpiece, ensuring that the workpiece obtains an accurate position during machining and preventing its movement or deformation. Fixtures are designed to ensure that the part maintains a stable posture during machining, while facilitating various machining operations such as cutting, drilling, and grinding by the operator or automated equipment.

[0003] Most existing fixtures require manual operation to clamp and release parts. Manual operation means that every clamping and releasing action requires the direct participation of the operator, which greatly limits the efficiency of the machining process. In cases where frequent part changes or large-scale machining are required, manual operation will significantly extend the overall machining cycle. Utility Model Content

[0004] The purpose of this invention is to provide a fixture for automated parts processing. This device facilitates the automated clamping of parts, thus solving the problem of inconvenient automated clamping of parts in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated parts processing fixture includes a base, on which multiple movable plates are slidably connected in a ring array at the upper end. Clamping blocks are fixedly connected to the side walls of the movable plates. Multiple gears are rotatably connected in a ring array inside the base. Screws are fixedly connected to the side walls of the gears and are threadedly connected to the movable plates. A ring plate is rotatably disposed inside the base. A groove is provided at the upper end of the ring plate. Multiple tooth blocks are fixedly connected in a ring array at the bottom of the groove. The tooth blocks mesh with the side walls of the gears.

[0007] Preferably, the upper end of the base is provided with multiple sliding grooves, which are arranged in a circular array and are slidably connected to the movable plate.

[0008] Preferably, the inner wall of the chute is provided with a groove, and a baffle is slidably connected inside the groove, with the side wall of the baffle fitting against the side wall of the movable plate.

[0009] Preferably, two springs are fixedly connected to the inner wall of the slot, and the ends of the springs are fixedly connected to the side wall of the baffle.

[0010] Preferably, a motor is fixedly connected inside the lower end of the base, and a main gear is fixedly connected to the output end of the motor, with the main gear being rotatably connected to the interior of the base.

[0011] Preferably, a plurality of tooth blocks are fixedly connected to the inner wall of the ring plate, and the plurality of tooth blocks are distributed in a ring array, wherein the tooth blocks mesh with the side wall of the main gear.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The main gear is driven to rotate by the motor output. The engagement between the main gear and the second gear block causes the ring plate to rotate. The engagement between the first gear block and the gear causes multiple gears to rotate. Simultaneously, the gears drive the screw to rotate. The threaded engagement between the screw and the movable plate causes the movable plate to slide laterally. Multiple movable plates slide towards the center point of the base. The movable plates drive the clamping blocks to slide, so that the sidewalls of the clamping blocks contact and fit against the sidewalls of the parts. The parts are clamped and fixed by multiple clamping blocks. The motor-driven automatic clamping reduces the time spent manually clamping parts, thereby speeding up the processing flow and improving overall production efficiency. At the same time, by adjusting the threaded engagement between the screw and the movable plate, it can flexibly adapt to parts of different sizes and shapes, achieving wide applicability.

[0014] 2. When the movable plate slides laterally towards the center point of the base, it pushes the baffle to slide into the groove. At the same time, the spring is compressed. When the movable plate slides laterally outward from the center point of the base, the elasticity of the spring pushes the baffle, causing the baffle to slide from the inside of the groove. The baffle blocks the slide groove, effectively preventing debris and dust from entering the slide groove, protecting the normal operation of the slide groove and its internal mechanism, and extending the service life of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 An automated parts processing fixture includes a base 001. Multiple movable plates 102 are slidably connected in a ring array on the upper end of the base 001. Clamping blocks 103 are fixedly connected to the side walls of the movable plates 102. Multiple gears 104 are rotatably connected in a ring array inside the base 001. Screws 105 are fixedly connected to the side walls of the gears 104 and threadedly connected to the movable plates 102. An annular plate 002 is rotatably disposed inside the base 001. A groove 201 is provided at the upper end of the annular plate 002. Multiple toothed blocks 202 are fixedly connected in a ring array at the bottom of the groove 201. The toothed blocks 202 mesh with the side walls of the gears 104. The operator... The base 001 is fixed in the designated position inside the parts processing equipment. Then, the operator places the part to be processed on the upper part of the base 001. The ring plate 002 then rotates. Through the cooperation between the tooth block 202 and the gear 104, multiple gears 104 rotate accordingly. At the same time, the gears 104 drive the screw 105 to rotate. Then, through the threaded cooperation between the screw 105 and the movable plate 102, the movable plate 102 slides laterally. Multiple movable plates 102 slide towards the center point of the base 001. The movable plate 102 drives the clamping block 103 to slide, so that the side wall of the clamping block 103 contacts and fits against the side wall of the part. The part is clamped and fixed by multiple clamping blocks 103.

[0023] The upper end of the base 001 is provided with multiple sliding grooves 101, which are arranged in a circular array. The sliding grooves 101 are slidably connected to the movable plate 102, and the movable plate 102 is guided and limited by the sliding grooves 101.

[0024] The inner wall of the slide 101 is provided with a groove 106, and a baffle 107 is slidably connected inside the groove 106. The side wall of the baffle 107 is in contact with the side wall of the movable plate 102. The slide 101 is blocked by the baffle 107. When the movable plate 102 slides laterally toward the center point of the base 001, it pushes the baffle 107 to slide into the groove 106.

[0025] Two springs 108 are fixedly connected to the inner wall of the slot 106. The ends of the springs 108 are fixedly connected to the side wall of the baffle 107. When the movable plate 102 slides laterally outward from the center point of the base 001, the elasticity of the springs 108 pushes the baffle 107, causing the baffle 107 to slide from inside the slot 106.

[0026] A motor 003 is fixedly connected inside the lower end of the base 001. A main gear 301 is fixedly connected to the output end of the motor 003. The main gear 301 is rotatably connected to the inside of the base 001. The main gear 301 is driven to rotate through the output end of the motor 003.

[0027] Multiple toothed blocks 203 are fixedly connected to the inner wall of the ring plate 002. The multiple toothed blocks 203 are arranged in a ring array. The toothed blocks 203 mesh with the side wall of the main gear 301. When the main gear 301 rotates, the ring plate 002 rotates through the cooperation between it and the toothed blocks 203.

[0028] In this invention, the operator fixes the base 001 at a designated position within the parts processing equipment. The operator then places the part to be processed on the upper part of the base 001. The output of the motor 003 drives the main gear 301 to rotate. Through the engagement between the main gear 301 and the second gear block 203, the ring plate 002 rotates. Then, through the engagement between the first gear block 202 and the gear 104, multiple gears 104 rotate accordingly. Simultaneously, the gears 104 drive the screw 105 to rotate. Through the threaded engagement between the screw 105 and the movable plate 102, the movable plate 102 slides laterally. Multiple movable plates 102 slide towards the center point of the base 001. The movable plates 102 drive the clamping blocks 103 to slide, causing the sidewalls of the clamping blocks 103 to contact and adhere to the sidewalls of the parts. Multiple clamping blocks 103 automatically clamp and fix the parts, thus facilitating automated clamping and fixing of the parts.

[0029] When it is necessary to release the clamp on the part, the output end of the motor 003 drives the main gear 301 to rotate in the opposite direction, causing the ring plate 002 to rotate in the opposite direction. At the same time, multiple gears 104 rotate in the opposite direction, and the gears 104 drive the screw 105 to rotate in the opposite direction, causing the movable plate 102 to slide laterally outward from the center point of the base 001. The clamping block 103 releases the clamp on the part, and then the operator removes the part.

[0030] When the movable plate 102 slides laterally toward the center point of the base 001, it pushes the baffle 107 to slide into the groove 106. At the same time, the spring 108 is compressed. When the movable plate 102 slides laterally outward from the center point of the base 001, the elasticity of the spring 108 pushes the baffle 107, causing the baffle 107 to slide out of the groove 106. The baffle 107 blocks the slide groove 101, thereby preventing debris and dust generated during the processing of parts from entering the slide groove 101.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
