Background
The existing processing clamp is designed corresponding to a specific product structure, and can only process 1-2 working faces of a workpiece at one time, so that the efficiency is low. In the production of multiple varieties of small batches of products, frequent replacement of clamps increases production costs and time. Some clamps have a complex operation process, which may cause errors in the use process of operators, and affect the processing efficiency and quality.
Disclosure of utility model
The utility model aims to overcome the defects of the prior art, and provides a gland four-side machining clamp which can realize rapid and efficient clamping of a universal workpiece and multi-side machining of the workpiece.
The technical scheme for achieving the purpose is that the gland four-side processing clamp comprises a bottom plate, a clamp screw and a pressing block;
The fixture comprises a base plate, a plurality of blind holes, fixture screws, pressing blocks, fasteners, a turnover mechanism and a turnover mechanism, wherein the blind holes are formed in the base plate at equal intervals and are arranged in a straight line along the direction of the base plate, the fixture screws are inserted into the blind holes, the pressing blocks and the fasteners are sleeved on the fixture screws, each workpiece to be processed is arranged on the base plate and positioned between the two fixture screws, the pressing blocks are bridged on the top surfaces of any two adjacent workpieces and fastened through the fasteners to tightly press the workpiece on the surface of the base plate, and the base plate is connected with the turnover mechanism and can be turned around the central axis of the length direction of the base plate under the driving of the turnover mechanism.
Further, the pressing blocks are divided into a middle pressing block and two end pressing blocks, the pressing blocks at the two ends are pressing blocks sleeved on clamp screws at the two ends of the blind hole which are linearly arranged, the rest is the middle pressing block, the middle pressing block is bridged on the top surfaces of any two adjacent workpieces, one sides of the pressing blocks at the two ends are pressed on the top surfaces of the workpieces, and the other sides of the pressing blocks are supported through supporting columns arranged on the bottom plate.
Further, a marking point for marking a work position where the work piece is placed is arranged at the middle point of the connecting line of any two adjacent blind holes.
Further, the surface of the bottom plate is provided with 4 locating pins corresponding to each station.
Further, a processing window leading to the bottom of the workpiece is arranged on the bottom plate corresponding to the placing position of the workpiece.
Further, the turnover mechanism performs positioning and locking by taking 90 degrees as a turnover angle.
The gland four-side processing clamp has the following advantages:
1. The clamping device can clamp a plurality of workpieces at one time, and can process threaded holes on two sides of the workpieces at the same time. If necessary, four faces can be processed simultaneously.
2. The clamping device can be used for clamping most types of workpieces without independently designing the workpieces with different structures.
3. The clamping operation is simple, and the efficiency is high.
4. The turnover of the workpiece can be realized, so that the workpiece can be conveniently machined in four directions.

Detailed Description
In order to better understand the technical solution of the present utility model, the following detailed description is given by way of specific examples:
Referring to fig. 1 and 2, the four-side processing clamp for a gland is used for processing threaded holes on front and rear end surfaces of a workpiece.
A row of 5 blind holes are arranged on the bottom plate 1, and the blind holes are distributed along the direction of the bottom plate 1 at equal intervals in a straight line. The blind hole is internally inserted with a clamp screw rod 2, and the clamp screw rod 2 is sleeved with a pressing block 3 and a fastening piece 4. The clamp can clamp a row of 5 workpieces 5 at a time.
The compacts are divided into a middle compact 31 and two-end compacts 32. The pressing blocks 32 at the two ends are pressing blocks sleeved on the clamp screw rods 2 at the two ends of the blind holes which are arranged in a straight line, and the rest pressing blocks are middle pressing blocks 31. The intermediate compact is attached across 31 to the top surface of any adjacent two workpieces 5. The pressing blocks 32 at the two ends are pressed on the top surface of the workpiece 5 at one side and supported by the supporting columns 6 arranged on the bottom plate 1 at the other side. The support column can ensure the balance of the two-end pressing blocks 32.
In order to realize multi-surface machining of a workpiece, the bottom plate 1 is connected with the turnover mechanism and can turn around the central axis of the length direction of the bottom plate under the drive of the turnover mechanism. The face facing directly above is usually default to the face to be machined facing the machining tool. For example, the top surface of the workpiece is first machined, and after the top surface is machined, the turning structure is turned over to turn the front end surface and the rear end surface of the workpiece to right above in order for machining. If the bottom surface of the workpiece facing the bottom plate has the content to be processed, a processing window can be opened at a corresponding position on the bottom plate according to the requirement, and then the surface is turned over to the upper part for processing. The turnover mechanism performs positioning and locking by taking 90 degrees as a turnover angle so as to ensure that the bottom plate is stable and reliable when being processed in all directions.
In some cases, four faces of the workpiece may be machined simultaneously by the machining tools in four directions.
Further, a marking point for marking the placing position of the workpiece is arranged at the middle point of the connecting line of any two adjacent blind holes. The surface of the bottom plate is provided with 4 locating pins corresponding to each station. This structural style can make operating personnel can be quick accurate fix a position the work piece to set up the work piece in clamping position fast, can promote production efficiency.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the utility model, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the utility model as long as they fall within the true spirit of the utility model.
