Description

A new fixture for long-distance parts

technical field

The utility model relates to a fixture, more specifically, it relates to a novel fixture for long-distance parts.

Background technique

Fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection; especially for the parts to be processed on the machine tool, it needs to be clamped for grinding or turning. .

In the prior art, when turning or grinding long-distance parts, it needs to be fixed on the workbench of the CNC machine tool, but because of the limited stroke of the turning tool or sharpening tool, it is often necessary to turn or grind long-distance parts. One end of the machine is processed first, and after the processing is completed, the part is turned over and the other end is fixed on the turning tool (or sharpening tool) for further processing, which will lead to a decrease in processing efficiency, because when the part is turned over, the fixture needs to be opened first , and then turn the part over, and then clamp it through the fixture, which will increase the workload of the operator, and when the part is clamped again, it will easily cause the offset of the part, which will lead to lower machining accuracy, so it is necessary to propose a A better solution to this problem.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a new type of fixture for long-distance parts, which can adjust the position of the parts, facilitate processing, have high processing efficiency and save costs.

In order to achieve the above object, the utility model provides the following technical solutions: a new fixture for long-distance parts, including a first splint and a second splint, the first splint is fixed on the workbench, the second splint and the second splint A splint is slidingly connected, the two ends of the second splint are provided with a limit fixing device, and a control device for controlling the sliding distance of the second splint is arranged between the first splint and the second splint, and the second splint An auxiliary limit device for auxiliary fixing parts is also provided on the top.

Preferably, the control device includes a gear and a rack, the rack is fixed on the first clamp, and the gear is arranged on the second clamp.

Preferably, the gear is also provided with a rocker for transmission.

Preferably, the limit fixing device includes a screw, a fastener and a nut, the screw is fixed on the second splint, and the fastener is sleeved on the screw and fixed by the nut.

Preferably, the second clamping plate is also provided with a limiting post for abutting against the side wall of the part.

Preferably, the fastener is provided with a flexible cushion.

Preferably, the auxiliary limiting device includes a strip plate and a bolt, the strip plate is provided with a fixing hole, the second splint is provided with a threaded hole, and the bolt is threaded with the threaded hole after passing through the fixing hole. connect.

Compared with the prior art, the utility model has the following advantages: by setting the first splint and the second splint, the first splint is fixed on the workbench, and the second splint is slidably connected with the first splint, so that when the parts pass through the limit When the position fixing device is fixed on the second splint, the second splint can be slid relative to the first splint through the control device to adjust the position of the parts on the second splint, so that the turning tool can be processed more conveniently and quickly. The situation that the operator turns over the parts is avoided, thereby saving costs and improving machining accuracy.

detailed description

A specific embodiment of a new type of fixture for long-distance parts of the present invention will be further described with reference to Fig. 1 to Fig. 4 .

As shown in Figure 1 and Figure 4, the first splint 5 is fixedly installed on the workbench 1 now, and the lower end surface of the first splint 5 is integrally formed with a T-shaped block, and the T-shaped block is formed in the T-shaped groove of the workbench 1 The first splint 5 is fixed on the workbench 1, and the upper surface of the first splint 5 is integrally formed with a dovetail block, and the lower surface of the second splint 3 is provided with a dovetail groove matching the dovetail block. The dovetail block extends into the dovetail groove to make the first splint 5 and the second splint 3 slidingly connected, and the upper end surface of the second splint 3 is also fixedly connected with a rack 10, and the rack 10 is fixed on one side of the second splint 3, And on the workbench 1, the bracket 6 is also fixedly connected, and the bracket 6 is provided with a through hole for placing the rotating shaft 7. Of course, as preferably, a ball bearing is arranged between the rotating shaft 7 and the bracket 6, so as to facilitate the rotation of the rotating shaft 7. One end of the rotating shaft 7 is fixedly equipped with a gear 9, the gear 9 meshes with the rack 10, and a rocker 8 is fixedly installed at the other end of the rotating shaft 7, and the rocking rod 8 is used to facilitate the operator to rotate the rotating shaft 7 so that the gear 9 drives the rack 10 transmission, so that the second splint 3 can be easily slipped relative to the first splint 5 .

Simultaneously, the two ends of the second splint 3 are also fixedly provided with a limit fixture 4, the limit fixture 4 is used to fix the part 2 on the second splint 3, the limit fixture 4 includes fasteners, screw rods and bolts , the fastener is a rectangular plate, one end of the rectangular plate is opened for the screw to pass through, the other end clamps the part 2, and a nut is threaded on the screw, and the nut is used to clamp the fastener to make the fastening The parts 2 are fixed against each other. Of course, it is more preferable to bond a flexible buffer pad on the lower surface of the fastener. The flexible buffer pad can be an elastic sponge, so that when the fastener presses the part 2, it can prevent the parts from Indentation is left on the surface of 2, so as to better protect the part 2. Of course, in order to better fasten the part 2, a plurality of limit fixtures 4 can be set on the second splint 3, so that the part 2 can be more Good clamping; more preferably, as shown in Figure 2 and Figure 3, a plurality of limit posts 12 are fixedly welded on one side of the second splint 2, and the limit posts 12 are arranged in a straight line, so that when it is necessary to When the part 2 is fixedly placed on the second clamping plate 3, one side of the part 2 can be in contact with the limit post 12, so that the part 2 can be vertically placed on the second clamping plate 3, and on the other side of the second clamping plate 3 One side is also provided with auxiliary limiting device 11, and auxiliary limiting device 11 comprises a strip plate, and the strip plate is provided with fixing holes, and a threaded hole is provided on the second clamping plate, when the part 2 is placed on the second clamping plate 3 When the bolt is drilled through the fixing hole and then threaded with the threaded hole, the part 2 can be fixed. Of course, a ring gasket can be added between the part 2 and the bolt to increase the contact area with the part 2, so as to better The protection to parts will not be damaged.

When the fixture is used to clamp the part 2, then the part 2 is ground by the turning tool on the lathe. After the grinding is completed at one end of the part 2, because the stroke of the turning tool is limited, it cannot be moved to the other end to continue processing , so that only the rocker 8 needs to be rotated, the rocker 8 drives the gear 9 to rotate, and the gear 9 drives the rack 10, so that the second splint 3 will slide relative to the first splint 5 to move the other end of the part 2 to the turning tool place, so that the turning tool can continue processing, which avoids the need for the operator to turn over the other end of the long-distance part 2 before continuing processing, thereby achieving the purpose of saving processing costs and improving processing accuracy.

The above descriptions are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present utility model all belong to the protection scope of the present utility model. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
