Detailed Description
Referring to fig. 1-5, the technical solution adopted by the present embodiment is: a tool clamp comprises a placing plate 1, a T-shaped block 2, a movable block 3 and a pressing plate 4. Limiting plates 11 are arranged at two adjacent end edges of the upper side of the placing plate 1, and a trapezoidal groove 12 is arranged at the lower side of the placing plate 1 along the length direction. When the workpiece is placed, the workpiece is placed tightly close to the limiting plate 11. The T-shaped block 2 is positioned in the trapezoidal groove 12 and can move along the trapezoidal groove 12. The movable block 3 is positioned on the upper side of the placing plate 1 and is connected with the T-shaped block 2 through a bolt for fixing a workpiece. In order to ensure the machining precision of the workpiece, the surface of the part which is in contact with the surface of the workpiece needs to ensure the smooth finish of the plane of the part, so that the workpiece and the clamp can be completely and better attached. If the surface of the clamp is too rough, the machined workpiece surface is not smooth enough, and the machining quality is greatly influenced.
The limiting plates 11 comprise a first limiting plate 111 and a second limiting plate 112, the first limiting plate 111 and the second limiting plate 112 are perpendicular to each other, and a yielding hole 13 is formed in the joint of the first limiting plate 111 and the second limiting plate 112. And a 'ear-shaped' abdicating hole 13 is formed on the right-angle edge at the corner. Therefore, both sides of the workpiece can be attached to both sides of the clamp, and the problem that the right-angle side of the cutter cannot be machined when the corner is machined is solved.
The T-shaped block 2 comprises a T-shaped body 21 and a convex block 22 which are integrally formed, a first threaded hole 23 is formed in the upper side of the T-shaped body 21, the convex block 22 is arranged at one end far away from the first threaded hole 23, and a second threaded hole 24 is formed in one side, far away from the first threaded hole 23, of the convex block 22. After a workpiece is placed in the clamping process, the T-shaped block 2 is moved along the trapezoidal groove 12, the position of the T-shaped block 2 is determined by the contact of the upper edge of the T-shaped body 21 and the workpiece, and the T-shaped block 2 is fixed by a magnetic disc of a machine tool after the position is determined. In order to make the T-shaped body 21 contact the workpiece and facilitate the positioning of the T-shaped block 2, the height of the T-shaped body 21 should be slightly higher than the thickness of the placing plate 1, and in this embodiment the T-shaped body 21 is 31mm thicker than the placing plate 1.
The movable block 3 is provided with a fixing groove 31 and a through hole 32 in parallel along the length direction, and a third threaded hole 33 is provided on the side wall of one end of the movable block 3 close to the through hole 32, and the third threaded hole 33 is connected with the through hole 32. In operation, the movable block 3 is placed on the upper side of the T-shaped block 2. The fixing groove 31 is aligned with the first threaded hole 23, the protrusion 22 is located in the through hole 32, and since the length of the through hole 32 is greater than that of the protrusion 22, when a worker connects the two through holes with a screw, the worker can adjust the position of the protrusion 22 in the through hole 32 by screwing the screw into the through hole, that is, adjust the force of the movable block 3 to extrude a workpiece. For the movable block 3, since the height of the allen wrench is about 30mm, the height of the movable block 3 should be limited to less than 30mm, so that the allen wrench can conveniently rotate and press the screw in the fixing groove 31.
In a specific use process, firstly, the position of the T-shaped block 2 is determined by contacting the upper edge of the T-shaped body 21 with a workpiece, and then the T-shaped block 2 is firmly fixed by a magnetic disc matched with the lower part of the clamp, so that the T-shaped block 2 cannot move during processing. In the second step, the movable block 3 is placed on the upper surface of the T-shaped block 2, and one side of the movable block 3 is in contact with the workpiece. Then, the fixing groove 31 is connected with the second threaded hole 24 by using a screw, and then another screw passes through the third threaded hole 33 and is screwed into the second threaded hole 24 on the projection 22, and the screw screwing depth is adjusted by a hexagon wrench to enable the movable block 3 to slide forwards, so that a forward thrust is generated, and the movable block 3 tightly presses the workpiece. The workpiece can not be deviated in the machining process. And thirdly, locking the screw in the fixing groove 31 by using a hexagonal wrench, and tightly fixing the movable block 3 and the T-shaped block 2 together to ensure that the movable block 3 keeps pressing force on the workpiece.
The pressing plate 4 is positioned on the placing plate 1 and is symmetrical to the movable block 3. When the thickness of the workpiece is thin, the movable block 3 may cause the middle of the workpiece to arch when pressing the workpiece forward, thereby affecting the machining error. Therefore, the pressing plate 4 should be placed above the other side of the workpiece, a small side of the pressing plate 4 is firstly leaned against the upper surface of the workpiece, and the screwing depth of the socket head cap screw is adjusted by the socket head wrench to control the one side of the pressing plate 4 to press the workpiece downwards.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
