Description

Technical Field

[0001] The present invention relates to the technical field of jigs, and particularly to a workpiece fixing jig. Background Art

[0002] For a trapezoidal workpiece having regularly arranged rectangular ladder holes, when fixing and CNC shaping the workpiece, the workpiece is often fixed to the jig with bolts. Due to the shape and size limitations of the workpiece, the bolts are mostly of M3 specification. M3 bolts are easily damaged after multiple disassembly and assembly, and the force-bearing strength is not good. Summary of the Invention

[0003] The purpose of the present invention is to provide a workpiece fixing jig, which is provided with a movable block and a pressing block that cooperate to fix the workpiece, has good force-bearing and convenient operation, improves the disassembly and assembly efficiency of the workpiece, reduces component loss, and solves the problem that the bolts are easily damaged when directly fixing the workpiece with bolts.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] The workpiece fixing jig includes a base plate, a movable block, and a pressing block. The base plate is provided with an upwardly protruding positioning table and a sliding groove. The movable block is slidably arranged in the sliding groove. The pressing block is provided with a concave buckle, and the movable block is provided with a convex buckle.

[0006] Thus, the positioning table is used to place the workpiece. The workpiece is in a ladder shape and has a hollow rectangular ladder hole. The positioning table is inserted into the ladder hole to position the workpiece. The movable block can slide, and is connected to the pressing block through the connection structure of the convex buckle and the concave buckle, and drives the pressing block to press the workpiece, completing the pressing of the workpiece, and solving the problem that the bolts are easily damaged when directly fixing the workpiece with bolts.

[0007] In some embodiments, the movable block can slide in the horizontal and vertical directions.

[0008] Thus, the horizontal movement of the movable block realizes the connection of the convex buckle and the concave buckle, and then the vertical movement drives the pressing block to press the workpiece downward.

[0009] In some embodiments, the pressing block is provided with a connecting body, the concave buckle is arranged on the connecting body, the base plate is provided with a vertical groove capable of accommodating the connecting body, and the base plate is further provided with a horizontal groove capable of accommodating the convex buckle. The vertical groove is communicated with the horizontal groove, and the convex buckle can slide in the vertical groove.

[0010] Thus, the vertical groove has a guiding function. The connecting body can slide up and down along the vertical groove, and the convex buckle can slide in the horizontal groove. When the concave buckle slides to the interface of the vertical groove and the horizontal groove, the convex buckle can be buckled to the concave buckle to complete the buckling. Then, the movable block drives the pressing block to slide downward in the vertical direction.

[0011] In some embodiments, the movable block can be fixed to the sliding groove through a fastener.

[0012] Thus, after the movable block slides into place, it is fixed by a fastener.

[0013] In some embodiments, the movable block is provided with a stepped hole, the bottom of the sliding groove is provided with a threaded hole, and the fastener is a bolt body.

[0014] Thus, the fastener is a bolt body and is fixed by screwing through a threaded structure.

[0015] In some embodiments, the base plate is further provided with a limiting groove, and the movable block is provided with a guiding strip that cooperates with the limiting groove.

[0016] Thus, the cooperation between the limiting groove and the guiding strip facilitates the precise and smooth sliding of the movable block.

[0017] In some embodiments, a limiting block is provided at the notch of the limiting groove.

[0018] Thus, the limiting block can prevent the movable block from disengaging from the sliding groove.

[0019] In some embodiments, the base plate is further provided with a reset spring.

[0020] Thus, the reset spring can use the restoring force of the spring to push the movable block back to its original position.

[0021] In some embodiments, the reset spring includes a first spring and a second spring. A first spring hole is provided at the bottom of the sliding groove. One end of the first spring is connected to the first spring hole, and the other end of the first spring abuts against the bottom surface of the movable block;

[0022] A second spring hole is provided on the side surface of the movable block that slides horizontally. One end of the second spring is connected to the second spring hole, and the other end of the second spring abuts against the side surface of the sliding groove.

[0023] Thus, the first spring is used for resetting in the vertical direction, and the second spring is used for resetting in the horizontal direction, enabling the movable block to automatically reset.

[0024] In some embodiments, the bolt body is an M5 bolt, and the base plate is provided with a handle.

[0025] Thus, the handle facilitates the handling of the jig, and the mechanical strength of the M5 bolt can meet the requirements for long-term use.

[0026] Advantages of the present invention: The pressing block presses the workpiece. The pressing block is connected to the movable block through a buckle structure. The movable block drives the pressing block to press the workpiece downward. After pressing, the movable block is fixed by a bolt body, completing the pressing of the workpiece. The workpiece is pressed in a transfer manner and is not directly fixed to the workpiece by a bolt body, which can improve the mechanical strength and service life of the pressing components, enabling the selection of a bolt body with a larger size specification and reducing the loss of components;

[0027] The movable block and the pressing block are respectively provided with a convex buckle and a concave buckle connection structure. The buckling is achieved through horizontal sliding, and the pressing is achieved through vertical sliding. The structure is reliable, has good stress, is convenient to operate, effectively improves the positioning accuracy and the fixing reliability, and improves the quality of the processing efficiency.
