Description

Technical Field

[0001] The utility model relates to the technical field of component positioning, in particular to a lifting and lowering positioning mechanism. Background Art

[0002] The positioning of parts and components plays a relatively important role in the processing, testing and use of parts and components, which directly affects the processing quality, testing accuracy and performance of parts and components.

[0003] Chinese utility model patent: Publication number CN203956786U, discloses a positioning mechanism, including a positioning base and a positioning member, the positioning member is movably arranged on the positioning base along the adjustment direction of the positioning member, the positioning mechanism also includes an adjustment block slidably matched with the adjustment groove on the positioning base, the adjustment block has at least two adjustment surfaces that are blocked with the positioning member, and within at least one unidirectional sliding stroke of the adjustment block, each of the adjustment surfaces applies a force on the positioning member in the adjustment direction of the positioning member.

[0004] In the prior art CN203956786U, when in use, the adjustment block has at least two adjustment surfaces that engage with the positioning member. When the operator pushes and pulls the adjustment block, the positioning position of the positioning member can be changed without disassembling the positioning mechanism. Obviously, compared with the content introduced in the background technology, the above structure can shorten the operation time of the positioning mechanism and has a higher working efficiency.

[0005] However, the lifting and lowering adjustment in the prior art needs to be achieved with the help of an adjusting block. However, when the adjusting block slides, it is subjected to extrusion pressure. When manually adjusted by personnel, the friction force on the adjusting block is relatively large, which makes it more laborious for personnel to operate. In addition, when performing the lifting and lowering adjustment, the distance that the positioning member can move through the adjusting block is relatively limited, resulting in a small operating space when positioning, clamping and processing parts. Therefore, a liftable positioning mechanism is needed to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a liftable positioning mechanism, which has the advantages of labor-saving operation and increased adjustable distance during lifting and adjustment, and solves the problems of labor-intensive operation steps and small adjustable distance during use of the device in the prior art.

At this time, the positioning piece can be directly inserted into the top of the positioning base, and the bottom of the positioning piece can pass through the second limit frame and the first limit frame. When the positioning piece is lifted and lowered, the steering rod installed on the top of the screw body can be rotated to rotate the screw body, and then the second limit frame is moved vertically in the slide groove, thereby realizing the lifting and lowering operation of the positioning piece.

[0014] Preferably, one end of the first limiting frame facing away from the positioning base is movably sleeved on the bottom of the positioning member.

[0015] By movably sleeved one end of the first limiting frame away from the positioning base on the bottom of the positioning member, when the positioning member moves downward, the bottom of the positioning member can be limited by the first limiting frame, thereby ensuring that the moving direction of the positioning member remains vertical.

[0016] Preferably, a screw hole is provided at the rear end of the second limiting frame, and the screw body is threadedly connected to the second limiting frame through the screw hole, and the second limiting frame is perpendicular to the positioning base.

[0017] A screw hole is opened at the rear end of the second limit frame, and the screw body is threadedly connected to the second limit frame through the screw hole. At the same time, the second limit frame is perpendicular to the positioning base, so that when the screw body is rotated, the second limit frame can move vertically along the slide groove direction.

[0018] Preferably, the top of the screw body passes through the positioning base and is fixedly mounted with a transverse rotating rod, and the screw body is in contact with the positioning base but is not fixedly connected.
