Description

Technical Field

[0001] The present invention relates to the technical field of machining equipment, and particularly to a fixture for machining. Background Art

[0002] Fixtures for machining are one of the key tools in modern manufacturing systems. Their background technology is profound and has a long history. As early as the 18th - 19th centuries, with the advent of machine tools such as lathes, simple chucks and other fixtures came into being for clamping workpieces for machining. With the diversification of metal cutting machine tools, general fixtures such as vises have gradually become popular. Since the 20th century, with the transformation of production modes and technological innovations, the functions and types of fixtures have been continuously enriched, including group fixtures, modular fixtures and special fixtures, etc., to meet different processing requirements. Nowadays, fixtures have become a key factor restricting the progress of metal processing technology, and their professionalism and technical content are gradually being taken seriously, continuously promoting the development of the machining field.

[0003] During the actual use of existing devices, when a workpiece is subjected to cutting and polishing, a large amount of cutting fluid is often sprayed to cool the workpiece. However, the sprayed cutting fluid is easily combined with the chips generated by cutting the workpiece, thus adhering to the surface of the workpiece, affecting the normal operation of the tool and the machining quality of the workpiece. Therefore, a fixture for machining is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks in the prior art that when a workpiece is subjected to cutting and polishing, a large amount of cutting fluid is often sprayed to cool the workpiece, but the sprayed cutting fluid is easily combined with the chips generated by cutting the workpiece, thus adhering to the surface of the workpiece, affecting the normal operation of the tool and the machining quality of the workpiece, and to propose a fixture for machining.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: A fixture for machining, comprising a workbench. A fixed base is fixedly connected to the left side of the workbench. A swing mechanism is fixedly connected to the upper part of the fixed base. The swing mechanism includes a swing housing fixedly connected to the top of the fixed base. A third motor is arranged at the lower part of the swing housing. A reciprocating gear is arranged at the output end of the third motor. The reciprocating gear is meshed and connected with a reciprocating groove. The reciprocating groove is slidably connected with the swing housing. The reciprocating groove is meshed and connected with a third gear. A connecting plate is fixedly connected to the side of the third gear away from the reciprocating groove. An adjusting mechanism is fixedly connected to the front end of the connecting plate. The adjusting mechanism includes an adjusting housing fixedly connected to the upper part of the connecting plate. A fourth motor is arranged at one side of the adjusting housing. A fourth gear is arranged at the output end of the fourth motor. The fourth gear is meshed and connected with a fifth gear. A rotating shaft is fixedly connected to the side of the fifth gear close to the adjusting housing. The rotating shaft is fixedly connected with an adjusting plate. A powerful blower is fixedly connected to the front end of the adjusting plate.

[0006] A chuck is rotatably connected to the left side of the fixed base. A workpiece is placed on the upper part of the chuck. When the workpiece is being machined by cutting, the third motor is started to drive the reciprocating groove to move left and right reciprocally. The movement of the reciprocating groove drives the meshed third gear to rotate left and right, and then drives the connecting plate to swing left and right, so as to control the powerful blower to swing left and right reciprocally, blowing off the cutting fluid and debris attached to the surface of the workpiece. By driving the rotating shaft to rotate through the fourth motor, the adjusting plate is driven to rotate, so as to adjust the blowing angle of the powerful blower and control the blowing range. A plurality of liquid leakage holes are formed in the upper part of the workbench.

[0007] The above technical solution further includes: A support plate is fixedly connected to the upper part of the chuck. Cylinders are symmetrically and fixedly connected to both sides of the support plate. A movable pressing plate is arranged at the output end of the cylinders.

[0008] A movable base is slidably connected to the right side of the workbench. A rotating mechanism is arranged inside the movable base.

[0009] The rotating mechanism includes a rotating housing fixedly connected inside the movable base. A second motor is arranged inside the rotating housing. A rotating assembly is arranged at the output end of the second motor.

[0010] The rotating assembly includes a first gear arranged at the output end of the second motor. The first gear is meshed and connected with a second gear.

[0011] The second gear is rotatably connected with the rotating housing. A chuck is fixedly connected to the side of the second gear away from the rotating housing.

[0012] Driving mechanisms are symmetrically and fixedly connected to both sides of the workbench. One side of the driving mechanism is fixedly connected to the movable base. The movable base is driven to move through the rotating mechanism.

[0013] The transmission mechanism includes transmission grooves fixedly connected to both sides of the workbench. A first motor is arranged inside the transmission grooves, and a transmission component is arranged at the output end of the first motor.

[0014] The transmission component includes a lead screw arranged at the output end of the first motor. The lead screw is rotatably connected to the transmission groove. A transmission block is threadedly connected to the upper part of the lead screw. The transmission block is slidably connected to the transmission groove. A moving base is fixedly connected to the side of the transmission block away from the transmission groove.

[0015] The present invention has the following beneficial effects: 1. In the present invention, after the workpiece is placed on the support plate and clamped by the chuck, the air cylinder can be started. The movable pressure plate is driven by the air cylinder to move downward to press both sides of the workpiece, thereby effectively increasing the clamping effect of the workpiece. During the processing of the workpiece, the swing mechanism can be started to drive the powerful blower to swing left and right in a cycle, so that the cutting fluid and processing debris attached to the surface of the workpiece can be blown off, ensuring that the surface of the workpiece is always clean during the processing. Moreover, the blowing angle of the powerful blower can be adjusted through the adjustment mechanism, thereby controlling the blowing range of the powerful blower.

[0016] 2. In the present invention, after the workpiece is placed on the support plate, the transmission mechanism can be started. The transmission mechanism drives the moving base to move. The movement of the moving base drives the chuck arranged on the upper part to move, thereby clamping and fixing both sides of the workpiece. When the workpiece needs to be turned over for processing, there is no need to disassemble the workpiece for turning. The rotating mechanism arranged inside the moving base can drive the chuck to rotate, and the rotation of the chuck drives the workpiece to turn over, which is convenient and fast.

[0021] A chuck 6 is rotatably connected to the left side of the fixed base 2. A workpiece 17 is placed on the upper part of the chuck 6. When the workpiece 17 is being machined, by starting the third motor 21, the reciprocating groove 13 is driven to move left and right reciprocally. The movement of the reciprocating groove 13 drives the meshing-connected third gear 23 to rotate left and right, and then drives the connecting plate 12 to swing left and right, thereby controlling the left and right reciprocating swing of the powerful blower 10 to blow off the cutting fluid and debris adhering to the surface of the workpiece 17.
