TECHNICAL FIELD

[0001] The application relates to the technical field of machining, in particular to a machining positioning clamp. BACKGROUND

[0002] The clamp refers to a device used for fixing a machining object in a correct position to accept construction or detection in the process of mechanical manufacturing, and is also called a fixture. In a broad sense, the device used for quickly, conveniently and safely mounting a workpiece in any process of a process can be called a clamp.

[0003] According to the related technology in the above, the inventors believe that the following problems still exist:

[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: Figs. 1-3 As shown, this utility model provides a machining positioning fixture, including a plate 1. An adjustment mechanism 2 is fixedly installed on one side of the top of the plate 1, and a clamping mechanism 3 is fixedly installed on the other side of the top of the plate 1. A mounting platform 4 is provided between the adjustment mechanism 2 and the clamping mechanism 3, and the mounting platform 4 is fixedly installed on the top of the plate 1. The adjustment mechanism 2 includes a fixing plate 202, which is fixedly installed on one side of the top of the plate 1. A groove 209 is formed at the top of the fixing plate 202. A first threaded rod 206 is rotatably installed between the inner walls of the two sides of the groove 209. One side of the first threaded rod 206 passes through the fixing plate 202 and is fixedly mounted. The first threaded rod 206 is equipped with a knob 205 and a slider 207 is threaded on its outer surface. Limiting blocks 208 are fixedly installed on both sides of the slider 207. Limiting grooves 201 are opened on both sides of the inner wall of the groove 209. The two limiting blocks 208 and the limiting grooves 201 are trapezoidal. A fixing block 203 is fixedly installed on the top of the slider 207. A first clamping plate 204 is fixedly installed on the end of the fixing block 203 facing the mounting platform 4. The slider 207 is driven to move by the first threaded rod 206. The slider 207 drives the fixing block 203 and the first clamping plate 204 to move, so that the first clamping plate 204 positions the workpiece horizontally.

[0020] The clamping mechanism 3 includes a base plate 304, a support plate 307 fixedly mounted on the top of the base plate 304, a second clamping plate 301 fixedly mounted on the side of the support plate 307 facing the mounting platform 4, a movable plate 308 slidably inserted into the top of the support plate 307, a sliding block 303 fixedly mounted on one side of the movable plate 308, and a groove 302 for cooperating with the sliding block 303 on one side of the support plate 307. The movable plate 308 is L-shaped, allowing the L-shaped movable plate 308 to simultaneously connect the support plate 307 and the mounting platform 4. The second threaded rod 306 is rotatably mounted on the top of the support plate 307. A handle 305 is fixedly mounted on the top of the second threaded rod 306, and the second threaded rod 306 is threadedly connected to the bottom of the moving plate 308. A pressure plate 300 is fixedly mounted on the side of the moving plate 308 facing away from the second threaded rod 306. By rotating the second threaded rod 306, the second threaded rod 306 drives the moving plate 308 to move up and down along the support plate 307, so that the support plate 307 can vertically fix the workpiece.

[0021] Working principle: First, place the workpiece to be processed on the top of the mounting table 4. Then, turn the knob 205 on one side of the adjustment mechanism 2. The knob 205 drives the first threaded rod 206 to rotate in the groove 209. The first threaded rod 206 drives the slider 207 to move. At the same time, the slider 207 can be prevented from jamming by the limit block 208 cooperating with the limit groove 201. Then, the slider 207 drives the fixing block 203 to move on the fixing plate 202. The fixing block 203 then drives the first clamping plate 204 to cooperate with the second clamping plate 301 to horizontally position and fix the workpiece.

[0022] Then, when it is necessary to fix the workpiece vertically, the handle 305 at the top of the clamping mechanism 3 can be turned. The handle 305 drives the second threaded rod 306 to rotate at the top of the support plate 307. Then the rotating second threaded rod 306 will drive the moving plate 308 to move. The moving plate 308 can move smoothly through the sliding block 303 and the sliding groove 302. Finally, the moving plate 308 drives the pressure plate 300 to fix the workpiece on the mounting table 4 vertically.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
