[0002] Cylindrical parts such as cylinders, bushings, and tubes are the most widely used basic components in industries such as machinery manufacturing, automotive, hydraulics, and electronics. In subsequent machining processes (such as turning, milling, drilling, welding, painting, or inspection), these parts need to be positioned and clamped before processing can proceed.

[0003] Existing multi-station fixtures require a large space for the placement and positioning clamping structure of columns when positioning and clamping them, and require multiple driving components to achieve multi-point clamping of multiple columns. Therefore, a multi-station column positioning and clamping fixture is needed. Utility Model Content

[0006] Furthermore, there are multiple gripper assemblies, and the multiple gripper assemblies are arranged in a linear array on the base.

[0007] Furthermore, each of the claw seats has multiple claws, and the multiple claws are distributed in a ring array on the claw seat.

[0008] Furthermore, the upper part of the claw seat is provided with a mounting hole, and the support rod is threadedly connected to the mounting hole.

[0009] Furthermore, the lower end of the support rod is a threaded section, and the diameter of the upper section of the support rod is larger than the diameter of the lower section.

[0010] Furthermore, the positioning seat has a positioning hole in the middle, and the positioning seat is fixedly connected to the base by screws.

[0011] Furthermore, the upper end of the sliding sleeve is provided with a tapered surface, and the tapered surface of the sliding sleeve is correspondingly arranged with the claw.

[0012] Compared with the prior art, the advantages of this utility model are as follows: it can achieve multi-point clamping of multiple columns through a single driving component, and the overall structure occupies little space. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example:

[0020] Please see Figure 1-4 The multi-station column positioning and clamping fixture shown includes a base 1, on which a gripper assembly is fixedly connected. The gripper assembly includes a gripper seat 201, a jaw 202 hinged to the jaw seat 201, and a support rod 203 detachably connected to the upper part of the jaw seat 201. A torsion spring is provided at the hinge point between the jaw 202 and the jaw seat 201. A clearance hole 101 is opened on the upper part of the base 1 directly above each gripper assembly. A positioning seat 3 is detachably connected to each clearance hole 101. A cylinder 4 is fixedly connected to the lower part of the base 1. A slide table 5 is fixedly connected to the piston rod of the cylinder 4. A sliding sleeve 6 is fixedly connected to the slide table 5. The sliding sleeve 6 is slidably connected to the jaw seat 201.

[0021] There are multiple gripper assemblies on the slide table, and these gripper assemblies are arranged in a linear array on the base 1. Each gripper seat 201 has multiple chucks 202. After the column is positioned, the column is clamped by the chucks 202, and the multiple ring array of chucks 202 can improve the clamping effect on the column.

[0022] The upper part of the claw seat 201 is provided with a mounting hole, and the lower end of the support rod 203 is a threaded section. The mounting hole is used to install support rods 203 of different diameters. The diameter of the upper section of the support rod 203 is larger than that of the lower section, which makes it easier to ensure that the support rod 203 is installed in place.

[0023] A positioning hole 301 is provided in the middle of the positioning seat 3. The positioning hole 301 is used to position and place the column. When the positioning seat 3 is installed, it is positioned along the clearance hole 101 on the base 1. After placement, it is fixedly connected to the base 1 by screws.

[0024] A tapered surface is provided at the upper end of the sliding sleeve 6. When the sliding sleeve 6 slides upward, the tapered surface of the sliding sleeve 6 will push the pawl 202 upward so that it retracts towards the center of the pawl seat 201.

[0025] The working principle of this utility model is as follows:

[0026] Before use, select the corresponding support rod 203 according to the length of the column and install it on the claw seat 201. Then select the positioning seat 3 corresponding to the diameter of the column and fix it on the base 1.

[0027] When placing the column, the column is placed on the support rod 203 along the positioning hole 301. Then the piston rod of the cylinder 4 extends, the slide table 5 slides upward, and when the sliding sleeve 6 slides upward, the conical surface of the sliding sleeve will push the cleaver 202 upward so that it retracts towards the center of the cleaver seat 201, and the cleaver 202 clamps the column.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
