Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a simple tooling fixture for a round tube workpiece. Background Art

[0002] During machining, some round tube workpieces need to be polished. During the polishing process, the round tube workpiece is prone to rolling, and generally needs to be fixed by a fixture.

[0003] The clamping table of existing simple tooling fixtures is generally solid iron felt, and is usually placed directly on the workbench, with the bottom in direct contact with the workbench. When it needs to be moved, the clamping table itself is too heavy to be lifted directly by the friction of both hands. The only way is to tilt the clamping table to lift one side, then use the fingers to reach the bottom of the clamping table, and then use both hands to lift the clamping table to move it. When lifting and placing, it is easy for the clamping table to fall out of the hands and hit the fingers, which is dangerous. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a simple fixture for a round tube workpiece to solve the above problem.

[0005] The top of the workbench is provided with a circle tube workpiece, and the bottom of the circle tube is provided with a circle tube limit switch, and the bottom of the circle tube is provided with a circle tube limit switch.

[0006] According to the simple tooling fixture for a round tube workpiece, the installation mechanism includes an insertion tube, a connecting cap, a limiting sleeve and a fixing pin hole. The upper part of the connecting cap is threadedly sleeved with the bottom of the vertical tube of the fixture, the body of the insertion tube passes through the corresponding installation hole, the insertion tube is sleeved with the limiting sleeve on the lower outer side of the installation hole, and the insertion tube has a limiting hole at the middle position of the limiting sleeve.

[0007] According to the simple fixture for a round tube workpiece, the width of the pad is two-thirds of the diameter of the workpiece clamping platform.

[0008] According to the simple fixture for a round tube workpiece, the upper portion of the insertion tube is fixedly connected to the bottom portion of the fixture vertical tube via a connecting cap.

[0009] According to the simple fixture for a round tube workpiece, the outer diameter of the insertion tube corresponds to the diameter of the mounting hole.

[0010] According to the simple fixture for a round tube workpiece, the sleeve body of the limiting sleeve is provided with fixing pin holes at both ends of the limiting hole, and the limiting sleeve and the insertion tube are fixedly sleeved by limiting pins.

[0011] According to the simple fixture for a round tube workpiece, a rotating handle is fixedly connected to the top of the threaded rod.

[0012] The above solution has at least one of the following beneficial effects:

[0013] 1. The workbench of the utility model is provided with multiple mounting holes. With the installation mechanism and the vertical tube of the clamp, the clamp body can be movably installed in multiple positions of the workbench. With the horizontal tube sliding sleeve and the horizontal sliding rod, the clamping range can be greatly expanded, so that the clamp can clamp the workpiece at any position and direction on the workbench. At the same time, multiple mounting holes can also be used to set up multiple clamps to fix one workpiece at the same time or fix multiple workpieces separately, which improves the flexibility of clamping and enhances the practicality of the device.

[0014] 2. A pad with a width smaller than the diameter of the workpiece clamping table is provided under the workpiece clamping table of the utility model, which not only increases the height of the workpiece clamping table, but also allows a gap to be left between the bottom of the side of the workpiece clamping table and the workbench when the workpiece clamping table is moved. Both hands can be directly inserted into the bottom of the workpiece clamping table, and when placing the workpiece, the fingers can also be pulled out through the gap, which reduces the danger during transportation and movement and enhances the practicality of the device.

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0023] Reference Figure 1-3 The embodiment of the present invention provides a simple tooling fixture for a round tube workpiece, including a support frame 1 and a workbench 2. The top of the support frame 1 is fixedly connected to the workbench 2, and the sides of the workbench 2 are fixedly connected to side fences 3. A plurality of mounting holes 4 are arranged in an array above the workbench 2. A fixture vertical pipe 5 is provided above the workbench 2 through the mounting holes 4. A mounting mechanism 9 is provided at the bottom of the fixture vertical pipe 5. The mounting mechanism 9 includes an insertion tube 91, a connecting cap 92, a limiting sleeve 93 and a fixing pin hole 94. The top of the connecting cap 92 is threadedly sleeved with the bottom of the fixture vertical pipe 5. The top of the insertion tube 91 is fixedly connected to the bottom of the fixture vertical pipe 5 through the connecting cap 92. The body of the insertion tube 91 passes through the corresponding The outer diameter of the insertion tube 91 corresponds to the diameter of the mounting hole 4. The insertion tube 91 is sleeved with a limiting sleeve 93 on the outer side below the mounting hole 4. The insertion tube 91 is provided with a limiting hole at the middle position of the limiting sleeve 93. The sleeve body of the limiting sleeve 93 is provided with fixing pin holes 94 at both ends of the limiting hole. The limiting sleeve 93 and the insertion tube 91 are fixedly sleeved by limiting pins. The workbench 2 is provided with multiple mounting holes 4, which cooperate with the mounting mechanism 9 and the fixture vertical pipe 5. The fixture body can be movably installed at multiple positions of the workbench 2. It is also possible to use multiple mounting holes to simultaneously set multiple fixtures to fix one workpiece or to fix multiple workpieces separately, thereby improving the flexibility of clamping;

[0024] The top of the vertical tube 5 of the clamp is fixedly connected to a horizontal tube sliding sleeve 10, and the interior of the horizontal tube sliding sleeve 10 is slidably sleeved with a horizontal sliding rod 11. The top of the threaded rod 13 is fixedly connected to a rotating handle, and one end of the horizontal sliding rod 11 is fixedly connected to a threaded sleeve 12. The interior of the threaded sleeve 12 is threadedly connected to a threaded rod 13.
