Description

Technical Field

[0001] The utility model relates to the technical field of processing fixtures, in particular to a multi-angle processing fixture for mechanical processing. Background Technique

[0002] Mechanical processing fixtures are tools used to fix workpieces for machining on machine tools. They usually consist of a fixture body, a clamping device, and a positioning device. The design and selection of fixtures are very important for machining quality and efficiency because they can ensure the stability and accuracy of workpieces. Different types of fixtures are suitable for workpieces of different shapes and sizes. For example, parallel clamps are suitable for clamping flat workpieces, while chucks are suitable for clamping round workpieces.

[0003] Processing fixtures can ensure the stability and accuracy of workpieces during the machining process, but there are still some problems: 1) The traditional square pipe processing fixture is not convenient to adjust the inclination angle. Therefore, when machining the inclination angle on the outer wall of the square pipe, the processing difficulty is great; 2) For the square pipe fixture using the manual feeding method, after feeding, it is necessary to manually adjust the horizontal position to ensure that the machining position is aligned with the machining equipment. Manual adjustment has certain safety hazards, slow adjustment speed and low accuracy; 3) The production and use costs are low; Therefore, in view of the above current situation, there is an urgent need to develop a multi-angle processing fixture for mechanical processing to overcome the deficiencies in the current practical applications and meet the current needs. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-angle processing fixture for mechanical processing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A multi-angle processing fixture for mechanical processing, including a base, a fixture, and a drive housing. An arc-shaped chute is provided at the middle position of the base. An arc-shaped slider is welded to the bottom of the fixture, and the arc-shaped slider is slidably connected to the arc-shaped chute. The drive housing is installed on one side of the fixture;

[0006] A locking bolt is provided on one side of the base. The locking bolt is threadedly connected to the base. A number of arc-shaped distributed positioning grooves are provided on one side of the arc-shaped slider, and the positioning grooves are adapted to the end of the locking bolt. Specifically, the arc-shaped slider is locked to the base through the locking bolt so that it maintains a fixed angle and cannot slide randomly. The number of positioning grooves is arranged at a specific spacing. When the locking bolt is sequentially adapted to them, the fixture can respectively maintain the inclination states of 30 degrees, 60 degrees, and 90 degrees.

[0007] Preferably, the driving housing further includes a support beam, a driving wheel, a telescopic cylinder, a transmission shaft, bevel gears and a motor. The support beam is inclined and installed on the side wall of the driving housing. A hinge seat is installed on the side wall of the arc-shaped slider. The end of the support beam is hinged to the hinge seat. The bottom end of the telescopic cylinder is hinged to the side wall of the arc-shaped slider, and the top end of the piston rod of the telescopic cylinder is hinged to the bottom edge of the support beam. The motor is fixedly installed on the bottom edge of the driving housing. The transmission shaft is rotatably arranged inside the driving housing. The bevel gear is nested and installed in the middle section of the transmission shaft, and the driving wheel is nested and installed at the end of the transmission shaft. The displacement of the square pipe is driven by the provided driving wheel.

[0008] Preferably, there are two sets of transmission shafts, driving wheels and bevel gears. The two transmission shafts form a 90-degree angle, and the two bevel gears are meshed. Specifically, through the transmission effect of the bevel gears, a single transmission shaft cooperates with the bevel gears to drive the other transmission shaft to rotate synchronously.

[0009] Preferably, the bottom end of a single transmission shaft penetrates the driving housing and is drivingly connected to the motor. Specifically, the motor cooperates with the transmission shaft to drive the driving wheel to rotate.

[0010] Preferably, the base, the fixture and the driving housing are a set, and two sets of bases, fixtures and driving housings are distributed relatively up and down. Specifically, the two sets distributed up and down achieve the clamping effect on the square pipe.

[0011] Preferably, the clamping surfaces of the fixture form a 90-degree angle, and the clamping angles of the two driving wheels are 90 degrees, which is suitable for clamping and processing the square pipe.

[0012] Compared with the prior art, the present utility model provides a multi-angle processing fixture for mechanical processing, which has the following beneficial effects:

[0013] 1. A sliding connection is realized between the fixture and the base by using an arc-shaped slider. Both the arc-shaped slider and the arc-shaped chute are arc-shaped, and the rotation center is the horizontal center position of the square pipe. Therefore, after the square pipe is clamped and fixed by the fixture, its overall rotation angle can still be quickly adjusted to facilitate the processing operation of the inclined angle on the outer wall surface of the square pipe;

[0014] 2. The lateral position of the square pipe is finely adjusted by using driving wheels that are mutually at a 90-degree angle. The position adjustment is accurate and fast, and the potential safety hazards and operation difficulties existing in manual adjustment are reduced;

The plurality of positioning grooves 2011 are arranged at a specific spacing. When the locking bolt 101 is sequentially adapted thereto, the fixture 20 can respectively maintain the inclination states of 30 degrees, 60 degrees, and 90 degrees.

[0029] Preferably, the drive housing 30 further includes a support beam 301, a drive wheel 302, a telescopic cylinder 303, a transmission shaft 304, a bevel gear 305 and a motor 306.

The end of the support beam 301 is hinged to the hinge seat 202. The bottom end of the telescopic cylinder 303 is hinged to the side wall of the arc-shaped slider 201. The top end of the piston rod of the telescopic cylinder 303 is hinged to the bottom edge of the support beam 301. The motor 306 is fixedly provided at the bottom edge of the drive housing 30. The transmission shaft 304 is rotatably arranged inside the drive housing 30. The bevel gear 305 is nested and installed in the middle section of the transmission shaft 304.

[0030] Preferably, there are two sets of the transmission shaft 304, the drive wheel 302 and the bevel gear 305. The two transmission shafts 304 form a 90-degree angle, and the two bevel gears 305 are meshed.
