Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of machinery, and relates to a material carrying jig, in particular to an elastic material clamping tool, a use method and a processing equipment. BACKGROUND

[0002] A jig is a large category of tools for woodworking, blacksmithing, benchwork, machinery, electrical control and other handicrafts, and is mainly used as a tool for assisting in position control or action (or both). Jigs can be divided into three categories: process assembly jigs, project test jigs and circuit board test jigs.

[0003] The existing jigs usually use static limiting and dynamic clamping to fix the products, and the dynamic clamping usually uses a driver to perform the clamping action. As a result, the volume and cost of the jig are increased, and the jig is not suitable for small parts due to poor dexterity and low positioning accuracy. In addition, the power clamping is hard clamping, which can easily cause scratches, clamping damage and other damages to small products, thereby reducing the yield of finished products and affecting economic benefits.

[0004] For example, a jig (Chinese Patent No. 202221055003.1) has been disclosed in Chinese patent documents. The jig is suitable for fixing an object, and the jig comprises a base, a first fixing module and a first actuator. The first fixing module is arranged on the base, and the first fixing module comprises two first fixing members arranged on the base and slidable in a first direction, and a first synchronous connecting structure arranged on the base and connected between the two first fixing members. The first fixing member has two fixed rods arranged side by side in a second direction perpendicular to the first direction and forming a fixed part. The first synchronous connecting structure has two synchronous rods pivotally arranged on the base and overlapping into an X shape. The four ends of the two synchronous rods are respectively connected to the four fixed rods of the two first fixing members. The first actuator is used to drive the two first fixing members to slide towards or away from each other in the first direction, so as to fix the object by the fixed part of the two first fixing members in the first direction.

[0005] The above technical solution uses a synchronous connecting structure in the form of a rod body to realize power transmission and achieve synchronous clamping. However, there are many transmission components, and thus there are many transmission links, which can easily cause fatigue stress after frequent clamping actions, resulting in a decrease in transmission accuracy or even transmission failure, causing unbalanced clamping and losing the accuracy of product positioning. In addition, the jig cannot provide clamping power by itself and still needs external driving force, which is not conducive to adaptive clamping of small products and can easily cause scratches, clamping damage and other damages to small products. SUMMARY

[0006] The present application aims at the above-mentioned problems existing in the prior art, and provides an elastic material clamping tool and a use method and a processing equipment, which are capable of achieving self-flexible clamping by interference of transverse guide sliding and oblique guide sliding and spring force.

[0007] The present application can be realized by the following technical scheme: an elastic material clamping tool, comprising a base plate in the shape of an I-beam, a sliding sleeve embedded with a push plate in the I-shaped groove on both sides of the base plate, a spring abutting between the base plate and the push plate, a load cavity being opened on the top surface of the base plate and being in communication with the outside, a group of clamping claws being slidably connected on both sides of the load cavity, a guide connection being formed between the group of clamping claws and the push plate to drive opening and closing, and a locking assembly being arranged on the top surface of the base plate to limit the group of clamping claws.

[0008] In the above-mentioned elastic material clamping tool, the push plate is in the shape of an L-shaped plate body, a guide sliding straight groove is opened in the middle of the horizontal plate of the L-shaped plate body, and a buffer limiter is penetrated through the vertical plate of the L-shaped plate body.

[0009] In the above-mentioned elastic material clamping tool, the base plate is composed of a bottom flat plate and a T-shaped plate, the bottom flat plate is located below the push plate, the vertical plate of the T-shaped plate penetrates through the guide sliding straight groove, the horizontal plate of the T-shaped plate is located above the push plate, the length of the guide sliding straight groove is greater than the length of the vertical plate of the T-shaped plate, and the vertical plate of the T-shaped plate reciprocally slides along the guide sliding straight groove.

[0010] In the above-mentioned elastic material clamping tool, a mounting hole is opened on one side wall of the vertical plate of the T-shaped plate, the spring is horizontally arranged in the guide sliding straight groove, one end of the spring is inserted into the mounting hole, and the other end of the spring abuts against the end groove wall of the guide sliding straight groove; the buffer limiter and the spring are respectively located on both sides of the T-shaped plate.

[0011] In the above-mentioned elastic material clamping tool, horizontal sliding grooves are symmetrically arranged on both sides of the load cavity on the top surface of the T-shaped plate, the horizontal sliding grooves and the load cavity are in communication through interval tooth gaps, and the clamping claws are embedded in the horizontal sliding grooves and make the claw teeth thereof inserted into the load cavity from the interval tooth gaps.

[0012] In the above-mentioned elastic material clamping tool, an eight-shaped oblique groove is arranged on the push plate, the eight-shaped oblique grooves are symmetrically arranged on both sides of the guide sliding straight groove, the converging end of the eight-shaped oblique groove faces the buffer limiter, the expanding end of the eight-shaped oblique groove faces the spring, and the guide sliding pins penetrating through the group of clamping claws are correspondingly inserted into the eight-shaped oblique grooves to form guide sliding connections.

[0013] In the above-mentioned elastic material clamping tool, the locking assembly comprises a protective plate, a window is opened on the protective plate, the window is in matching communication with the load cavity, and the load cavity extends to the outside wall of the base plate to form a pushing opening.

[0014] In the above-mentioned elastic clamping fixture, a plurality of locking holes are opened on the top surface of the substrate, and a plurality of adjusting holes are correspondingly opened on the protective plate. The length of the adjusting holes is greater than the diameter of the locking holes. The plurality of adjusting holes and the plurality of locking holes are connected one-to-one and screws are inserted to form a locking and fixing mechanism.

[0015] A method for using a flexible clamping fixture includes the following steps:

[0016] S1. Push the push plate to compress the spring, causing the push plate to move forward.

[0018] S3. Release the push plate. The two ends of the spring press against the T-shaped plate and the push plate respectively. The push plate resets under the action of the spring force and causes the buffer limiter to abut against the T-shaped plate again, forcing the guide pin to drive the pawl to move towards the converging end of the figure-eight groove. As a result, a set of pawls move towards each other along the transverse groove, so that the pawl teeth of the two pawls pass through the gap between the teeth to press and position the product on both sides.

[0020] Compared with existing technologies, this flexible clamping tooling, its usage method, and processing equipment have the following advantages:

[0021] 1. The double-layer structure achieves the cross-over of lateral and oblique sliding.

Due to the symmetrical structure and the power provided by a spring, the overall movement is smooth and highly synchronized, ensuring a precise and accurate central clamping effect.

[0022] 2. Utilizing springs to generate independent clamping force, products can be fixed without external force, and the flexible clamping protects the products, especially for clamping and fixing small products, ensuring the yield of finished products.

[0023] 3. The overall structure is simple, reducing costs; the direct drive method improves the transmission effect; the operation is convenient, reducing the difficulty of material ordering and improving work efficiency. Attached Figure Description
