A valve plate positioning fixture

Abstract

This utility model discloses a positioning fixture for an explosion-proof valve plate. The fixture has a second groove, within which a first groove is recessed downwards. Each of the four edges of the second groove has a vertical right-angle positioning edge. The explosion-proof valve plate can be placed on the second groove and engaged and limited by the right-angle positioning edges. The top of each right-angle positioning edge is inclined to the outer surface of the top of the positioning fixture, forming a beveled edge that slopes outwards. The four right-angle positioning edges are rounded at their junctions. A through hole is provided in the first groove of the positioning fixture. This application utilizes a positioning fixture with a draft angle (larger at the top and smaller at the bottom) for positioning. This facilitates the placement of the explosion-proof valve plate while ensuring accuracy, reducing the risk of inaccurate placement due to repeated extension and retraction of the grippers, which could lead to poor welding.

Description

Technical Field

[0001] This utility model relates to the field of battery cover technology, specifically to a positioning fixture for a burst valve plate. Background Technology

[0002] In the current traditional cover plate structure, during the battery cover plate manufacturing process, the explosion-proof valve plate is fed using claw positioning or edge positioning. The explosion-proof valve plate is positioned by claw: the explosion-proof plate is placed in the positioning base, and the cylinder drives the four claws to retract and move to the set position to position the explosion-proof valve plate. However, the four-claw positioning is driven by the cylinder, and the size of the air source affects the size of the gripping force. The gripping claws frequently extend and retract, and the accuracy cannot be kept consistent. At the same time, if the air source is too large, it will deform the explosion-proof valve plate.

[0003] Explosion-proof valve plate positioning fixture: When the nozzle places the explosion-proof plate, a slight misalignment of the cylinder will prevent the explosion-proof valve plate from being placed into the secondary positioning fixture, resulting in deformation of the welded explosion-proof valve plate and poor welding. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned above in the background technology and to propose a valve plate positioning tool.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A positioning fixture for an explosion-proof valve disc is provided. The positioning fixture has a second groove, and a first groove is formed by a downward indentation in the second groove. Vertical right-angle positioning edges are formed at the four edges of the second groove. The explosion-proof valve disc can be placed on the second groove and locked and limited by the right-angle positioning edges.

[0007] As a further embodiment of this utility model: the top of the right-angle positioning edge and the top outer surface of the positioning fixture are inclined to form a beveled edge, and the beveled edge is inclined outward.

[0008] As a further embodiment of this utility model: the connection points of the four right-angled positioning edges are rounded.

[0009] As a further embodiment of this utility model: the positioning fixture has a through hole located at the first groove.

[0010] As a further embodiment of this utility model: the first groove is a waist-shaped hole.

[0011] As a further embodiment of this utility model: the beveled edges on both sides of the positioning fixture are recessed to one side to form a strip groove.

[0012] As a further embodiment of this utility model: a contact element is provided in the strip groove, and a sliding rod is transversely inserted in the strip groove, with one end of the sliding rod fixedly connected to the contact element.

[0013] As a further embodiment of this utility model: a pressing block is fixed to the other end of the slide rod, and an elastic element is also sleeved on the slide rod.

[0014] As a further embodiment of this invention, the elastic element is a compression spring.

[0015] As a further embodiment of this utility model: the outer surface of the contact element has the same inclination angle as the beveled edge.

[0016] The beneficial effects of this utility model are as follows: This application adopts a positioning fixture for side positioning, and the fixture has a draft angle, which is larger at the top and smaller at the bottom. This facilitates the placement of the explosion-proof valve plate while ensuring accuracy. It also reduces the welding defects caused by insufficient accuracy of the explosion-proof valve plate due to repeated extension and retraction of the grippers, which prevents the explosion-proof valve plate from being accurately placed into the explosion-proof valve hole of the substrate.

The top of the right-angle positioning edge 107 is inclined to the outer surface of the top of the positioning fixture 1 to form a beveled edge 104. The beveled edge 104 is inclined outward.

[0030] The explosion-proof valve plate 2 can be placed on the second groove 103 and engaged and limited by the right-angle positioning edge 107.

[0031] The four right-angled positioning edges 107 are connected by rounded corners 105.

[0032] The explosion-proof valve plate 2 is placed inside the positioning fixture 1. The beveled edge 104 in the positioning fixture 1 is designed to be larger at the top and smaller at the bottom, which makes it easy to put the explosion-proof valve plate into the fixture.

[0033] The positioning fixture 1 has a through hole 102 located at the first groove 101.

[0034] Stepped groove design:

[0035] Second groove 103: The groove where the explosion-proof valve plate 2 is placed on the main body.

[0036] First groove 101: a downward recessed area located at the center of the bottom of the second groove, shaped like an oblong hole.

[0037] Through hole 102: A hole that penetrates the bottom of the first groove (the hole can be used to install a sensor to identify the presence or absence of the explosion-proof valve plate).

[0038] Location mechanism:

[0039] Right-angle positioning edge 107: A vertical right-angle edge set on the four sides of the second groove, used to snap onto the explosion-proof valve plate 2 to achieve precise positioning.

[0040] 105 rounded corners: The four corners are designed with rounded corners to avoid stress concentration and facilitate the insertion of valve plates.

[0041] Beveled edge 104: The outward-sloping surface (larger at the top and smaller at the bottom) of the positioning fixture 1 guides the valve plate to slide smoothly into the second groove.

[0042] The difference between the first groove 101 and the second groove 103 is to accommodate explosion-proof valve plates of different sizes.

[0043] In another embodiment, see Figure 3 and Figure 4 Based on Embodiment 1 and Embodiment 2, the positioning fixture 1 has a groove 106 formed by recessing the beveled edges 104 on both sides to one side.

[0050] Slide bar 302: It runs horizontally through the strip groove 106, with a contact member 301 fixed at one end and a pressing block 303 connected at the other end.

[0051] Elastic element: A compression spring fitted on the slide bar (normally causing the contact element to retract into the strip groove 106).

[0052] This application adopts a positioning fixture for edge positioning. The fixture has a draft angle, which is larger at the top and smaller at the bottom. This facilitates the placement of the explosion-proof valve plate while ensuring accuracy. It also reduces the welding defects caused by insufficient accuracy of the explosion-proof valve plate due to repeated extension and retraction of the grippers, which prevents the explosion-proof valve plate from being accurately placed into the explosion-proof valve hole of the substrate.
