[0001] The present invention relates to the technical field of fixtures, and particularly to a dispensing and pressure-holding fixture. Background Art

[0002] At the joint of wire harnesses, in order to improve the connection strength, it is often necessary to improve the strength of the connection part by means of gluing. In the gluing process, the joint part is first dispensed with glue, and then the wire harness is placed in a fixture and pressed and held by the fixture to improve the gluing effect of the dispensed glue part. At present, most of the existing dispensing and pressure-holding fixtures have the disadvantages of low efficiency and poor stability. Therefore, there is an urgent need for a new type of dispensing and pressure-holding fixture to overcome the above defects. Summary of the Invention

[0003] The purpose of the present invention is to provide a dispensing and pressure-holding fixture to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] Preferably, a pressing plate is rotatably connected to the right end of the positioning plate, and permanent magnetic blocks are arranged on the end surface of the pressing plate facing the positioning plate and on the upper end surface of the positioning plate.

[0007] Preferably, a fixing block is fixedly connected to the positioning plate, and the fixing block is rotatably connected to one end of the pressing plate far from the permanent magnetic block through a first pin shaft.

[0008] Preferably, an opening and closing cylinder is rotatably connected to the bottom plate through a hinge seat, and the end of the telescopic rod of the opening and closing cylinder is rotatably connected to the end of one end of the pressing plate far from the permanent magnetic block through a second pin shaft.

[0009] Preferably, a pair of guide rails are fixedly connected to the bottom plate, guide rail grooves are arranged on the side walls on both sides of the pressing block, and the guide rail grooves are slidably connected to the guide rails.

[0010] Preferably, a spring groove is arranged on the right end surface of the positioning plate, a spring is arranged in the spring groove, and the right end of the spring extends out of the spring groove.

[0011] Preferably, a limiting groove is arranged on the left end surface of the pressing block, and a layer of rubber pad is arranged on the surface of the limiting groove.

[0012] Preferably, a group of evenly arranged clearance grooves are arranged on the wire groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: When the present invention performs press-fitting, first tie one end of the wire, apply glue at the knot, then place the wire into the wire groove and the knot at the joint groove, and the pressure cylinder drives the pressing block to move left to press the joint tightly. After pressing, keep it for a period of time and then move it away. Tying the knot improves the stress performance of the end of the wire, and the end of the wire has better buffering performance and is not easily broken. After placing the wire, if there is a shaking phenomenon, press the pressing plate on the joint to prevent the joint from shaking, and the permanent magnets adsorb each other to provide a pressing force for the pressing plate. The fixing block is rotationally connected to the pressing plate through the first pin shaft. The opening and closing cylinder expands and contracts to control the opening and closing of the pressing plate. The guide rail groove is slidably connected to the guide rail to realize the sliding installation of the pressing block. The spring plays a buffering role to prevent the pressing block from damaging the joint. When the pressing block moves left to press the joint tightly, the limiting groove limits the joint to prevent the joint from being pressed crooked, and the rubber pad further protects the joint. The clearance groove prevents the wire from being stuck in the wire groove and improves the efficiency of the wire being clamped into the wire groove. The present invention is a dispensing and pressure-holding fixture with a simple structure, convenient use and good bonding effect. BRIEF DESCRIPTION OF THE DRAWINGS
