Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a lifting clamping mechanism. Background Technology

[0002] Fixtures are widely used in industry for machining and assembling parts, serving as key tools to ensure production efficiency and product quality. Commonly used fixtures are typically made of metal or high-strength plastics, characterized by their robustness and durability. However, these traditional fixtures often lack automated lifting capabilities, making them difficult to integrate seamlessly with modern automated production equipment. This limits their application in complex machining and precision assembly tasks.

[0003] In addition, people are developing new automated equipment to automate the processing and assembly of workpieces. To this end, fixtures are equipped with sensors and actuators, which can automatically adjust their height and position according to preset programs, thereby completing various processing and assembly actions more efficiently. To achieve this goal, the fixtures must have automatic lifting capabilities. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a lifting clamping mechanism, which overcomes the defects of the existing clamping mechanism that cannot automatically lift and lower and cannot adapt to the needs of automated production equipment.

[0005] The technical solution of this utility model is as follows: a lifting clamping mechanism includes a base, a sliding groove mounting plate is vertically provided on one side of the base, a sliding groove is fixed on the sliding groove mounting plate, a sliding rail is provided in the sliding groove, the sliding rail can slide up and down along the sliding groove, and a clamp is provided on the sliding rail for processing workpieces.

[0006] In one embodiment of this utility model, a piston mounting plate is vertically provided on the base, and a piston cylinder is fixed on the piston mounting plate and arranged parallel to it. One end of the piston rod is inserted into the piston cylinder, and the other end is fixed to a movable plate. The slide rail is installed on the bottom surface of the movable plate.

[0007] Preferably, the slide mounting plate has a protective plate on the side facing the workpiece to cover the slide mounting plate, slide, and slide rail; the protective plate has a clearance at the corresponding machining fixture so that the fixture can extend out of the protective plate to process the workpiece.

[0008] The protective plate is also equipped with a solenoid valve to charge and release the piston cylinder and control the lifting and lowering of the piston rod.

[0009] In another embodiment of this utility model, a lead screw mounting plate is vertically provided on the base, and a lead screw motor is installed at its bottom end.

[0019] Reference Figure 1 A lifting clamping mechanism 10 is provided for controlling the lifting and lowering of a clamp 40 to process or assemble various types of workpieces. It includes a base 11, a sliding mounting plate 12 vertically mounted on one side of the base 11, a sliding groove 13 fixedly mounted on the sliding mounting plate 12, a slide rail 14 disposed within the sliding groove 13, the slide rail 14 being able to slide up and down along the sliding groove 13, and a clamp 40 mounted on the slide rail 14 for processing workpieces 3. The lifting clamping mechanism 10 controls the sliding and raising of the slide rail 14 within the sliding groove 13, thereby driving the clamp 40 mounted on the slide rail 14 to rise and fall, adjusting its position to facilitate workpiece processing.

[0020] It should be understood that the structure and function of the fixture 40 can be set according to the functions to be performed, and this application does not limit them.

[0021] The drive mechanism for raising and lowering the slide rail can be a pneumatic component, a lead screw assembly, etc.

[0022] In one embodiment of this utility model, the driving mechanism of the lifting clamp mechanism 10 is a pneumatic assembly. Specifically, a piston mounting plate 15 is vertically provided on the base 11, and a piston cylinder 16a is fixed on the piston mounting plate 15 and arranged parallel to it. One end of the piston rod 16b is inserted into the piston cylinder 16a, and the other end is fixed to a movable plate 17. The bottom surface of the movable plate 17 is equipped with the top surface of the aforementioned slide rail 14. When started, the piston rod 16b extends and retracts within the piston cylinder 16a, thereby pushing the movable plate 17 to rise and fall, causing the slide rail 14 under the movable plate 17 to slide up and down within the slide groove 13, thereby driving the clamp assembly 40 to rise and fall to process the workpiece.

[0023] Preferably, a protective plate 18 is provided on the side of the slide mounting plate 12 facing the workpiece to cover the slide mounting plate 12, the slide 13, and the slide rail 14. The protective plate 18 has a clearance 181 at the corresponding machining fixture, allowing the fixture 40 to extend out of the protective plate 18 to process the workpiece. The protective plate 18 protects the lifting fixture mechanism 10, preventing workpiece chips generated during processing from entering the lifting fixture mechanism 10 and damaging or affecting its operation.

[0024] A solenoid valve 19 is also installed on the protective plate 18 to charge and release the piston cylinder 16a and control the lifting and lowering of the piston rod 16b.

[0025] In another embodiment of this utility model, the driving mechanism of the lifting clamp mechanism 10 is a single-station lead screw assembly. Specifically, a lead screw mounting plate 15' is vertically provided on the base 11, and a lead screw motor 16' is installed at its bottom end. A lead screw 19 is installed on the motor shaft of the lead screw motor 16'. The top end of the lead screw 19 passes through the movable plate 17, and a lead screw nut 18' is provided on the lead screw 19. The lead screw motor 16' drives the lead screw 17' to rotate, thereby causing the lead screw nut 18' to rise and fall along the lead screw 19. This causes the lead screw nut 18' to push against the movable plate 17 and rise and fall along the lead screw 19, thereby driving the slide rail 14 installed under the movable plate 17 to rise and fall in the slide groove 13, and driving the clamp 40 on it to rise and fall.

[0026] In another embodiment of the present invention, the above-mentioned lifting clamping mechanism is used in a multi-station pressing and assembly machine, including a frame 1, a rotary table 2 disposed on the frame 1, a plurality of processing positions 3 disposed on the rotary table 2, and a plurality of pressing and assembly units 4 disposed at the center of the rotary table 2. Each pressing and assembly unit 4 contains the above-mentioned lifting clamping mechanism and performs the processing action set at the corresponding processing position.

[0027] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
