Description

Technical Field

[0001] This utility model relates to the field of electrode cylinder positioning technology, and more specifically, to an electrode cylinder positioning fixture. Background Technology

[0002] In electrode cylinder welding, precise alignment between electrode cylinders is crucial for ensuring welding quality. Traditional positioning methods typically involve manual angle adjustment or simple clamping. However, manual visual adjustment makes it difficult to guarantee the consistency of the circumferential angles of the electrode cylinder, especially for electrode cylinders with rib structures, where there is a risk of deviation in the fit between the ribs and the positioning device. Furthermore, conventional single-point or three-point clamping mechanisms can easily lead to uneven force on the electrode cylinder, potentially causing displacement during clamping. Existing positioning devices cannot accurately determine the presence of a workpiece, hindering automation.

[0003] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a high-precision electrode cylinder positioning fixture is provided.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An electrode cylinder positioning fixture includes a positioning base, a mounting plate, and clamping rods. The mounting plate is fixedly mounted on the upper end of the positioning base by support rods. Several clamping rods are evenly distributed along the circumference of the mounting plate, and each clamping rod is slidably mounted on the lower side of the mounting plate. At least two vertical guide rods are fixedly connected to the lower end of the mounting plate. A control plate is slidably mounted on the vertical guide rods. Several hinge seats are evenly distributed along the circumference of the control plate. Each hinge seat corresponds to a clamping rod, and the hinge seat and the corresponding clamping rod are connected by a control rod. The two ends of the control rod are hinged to the hinge seat and the clamping rod, respectively. A lifting controller is provided between the positioning base and the control plate.

[0007] The upper end of the positioning base is provided with a placement platform and a workpiece inspection mechanism. Both the placement platform and the workpiece inspection mechanism are provided with rollers for contacting the lower end of the electrode cylinder.

[0008] The upper end of the positioning base is equipped with a positioning device that cooperates with the protruding ribs of the electrode cylinder.

[0009] Preferably, the workpiece inspection mechanism includes a fixed frame and a sliding platform. The fixed frame is fixedly connected to the positioning base. The sliding platform is slidably mounted on the fixed frame in a vertical direction. A guide rod and a slide rod are fixedly connected to the lower end of the sliding platform. Both the guide rod and the slide rod are slidably connected to the fixed frame. A compression spring is sleeved on the outside of the slide rod. A proximity switch that cooperates with the guide rod is provided on one side of the fixed frame.

[0010] The roller is rotatably mounted on the sliding platform.

[0011] Preferably, the positioning device includes a vertical slide, a vertical slide plate, and a drive cylinder. The vertical slide is fixedly mounted on the positioning base, and the vertical slide plate is slidably connected to the vertical slide. The upper end of the vertical slide plate is provided with a U-shaped groove for engaging the protruding ribs of the electrode cylinder, and the upper end of the U-shaped groove is larger than the lower end.

[0012] The two ends of the drive cylinder are respectively hinged to the vertical slide and the vertical sliding plate.

[0013] Preferably, there are 8 clamping rods, the mounting plate includes a base plate and 8 extension plates evenly distributed along the circumference of the base plate, the lower end of the extension plates is provided with a slide rail, and the clamping rod is provided with a slider that slides in cooperation with the corresponding slide rail.

[0014] A clamping block is provided at the end of the clamping rod.

[0015] Preferably, there are pads at the four corners of the lower end of the positioning base.

[0016] Preferably, mounting rods are provided at the four corners of the upper end of the positioning base, and rollers are rotatably provided at the top of the mounting rods.

[0017] Preferably, the lifting controller is a cylinder or a linear motor, and the lower end of the lifting controller is hinged to the positioning base.

[0018] The advantages of this utility model compared with the prior art are as follows:

[0019] This invention utilizes a linkage structure of eight circumferentially distributed clamping rods, a control plate, and control rods to achieve synchronous radial movement of the clamping rods. This ensures uniform contact between the clamping block and the inner wall of the electrode cylinder, preventing deformation caused by localized stress concentration and improving clamping concentricity. A U-shaped groove positioning device, in conjunction with a drive cylinder, employs a U-shaped groove design that is wider at the top and narrower at the bottom. When the cylinder drives the vertical sliding plate upwards, it guides the electrode cylinder's ribs to automatically slide into the groove. The tangential force generated by the sliding plate's lifting action drives the electrode cylinder to fine-tune its angle, achieving adaptive correction of initial angle deviations. The guide rod of the workpiece detection mechanism, in conjunction with a proximity switch, detects whether the electrode cylinder has descended to the correct position, facilitating automation of subsequent processes.

The two ends of the control rod 24 are hinged to the hinge seat 23 and the clamping rod 3, respectively. When the control plate 22 moves up and down, the multiple control rods 24 drive the multiple clamping rods 3 to move synchronously.

[0033] A lifting controller 4 is provided between the positioning base 1 and the control board 22. The lifting controller 4 drives the control board 22 to move relative to the positioning base 1.

When there is an error in the initial angle of the electrode cylinder 8, the vertical slide plate 72 will push the electrode cylinder 8 to rotate, so that its position is aligned with the set angle.
