Description

Fixture for mass grinding of 60° bevels of clamp bars

technical field

The utility model relates to a fixture, in particular to a fixture for batch grinding 60° inclined surfaces of clip bars.

Background technique

At present, in production and processing, processing inclined surfaces has always been a difficult problem. The processing process is not only cumbersome, but also the usability of ordinary equipment is limited, the processing effect of inclined surfaces is poor, and the surface roughness does not meet the standard for use. Cutting can be used to process the workpiece on the inclined plane, but this method has a long processing cycle, and has high requirements for the operators, and the operators need to be trained; some enterprises will purchase some relatively advanced equipment, which can realize multi-axis processing. Angle adjustment is used to grind the inclined plane, but the cost of these equipment is high, and most enterprises cannot afford it. At the same time, these devices can only process a single piece of clamping strips, and require cumbersome workpiece clamping, adjustment, tool setting and other processes. The intermediate time taken is too long, and the number of clamping strips processed in one working cycle is far from Lower than expected, poor corporate earnings.

Utility model content

The utility model solves the above-mentioned shortcomings of the prior art, and provides a fixture with reasonable structure and convenient use for batch grinding of 60° slopes of clip bars, so as to realize batch production and improve the profit rate of enterprises, which is convenient and quick.

The technical solution adopted by the utility model to solve the technical problem: the clamp used for batch grinding the 60° slope of the clip bar includes a rectangular base plate, and a pair of left and right angles are installed on the rectangular base plate and the slope is 60°. Support, the workpiece clamping device is installed on the two right angle supports, the workpiece clamping device includes a group of positioning reference parts distributed at intervals, the positioning reference part includes the first small rectangular support installed on the right angle support The 45 wide single-slot extension plates on the first small rectangular support and the symmetrical groove square support installed on the right end of the 45 wide single-slot extension plates, the first small rectangular support is worn with these first small rectangular support strings The connecting rod is connected and arranged in an integrated structure, and the two ends of the connecting rod are pierced with reinforcement angles attached to the outer walls of the workpiece clamping device on both sides; the positioning reference part and the positioning reference part are installed with the second small rectangular Support, wherein the second small rectangular support is equipped with an elongated pressing plate. In this way, the rectangular base plate is the installation base plate, and the right angle support makes the use angle of the workpiece clamping device installed on it directly set at 60°, which saves tedious angle adjustment time and is very convenient and efficient in one step. The positioning reference part assists the positioning of the clip bar before installation, so that the clip bar can quickly find the accurate installation position, and the pressure plate is used to fix the guide block, so that it has good stability during processing, and the guide block will not be affected by the processing stress. Vibration ensures processing quality. At the same time, the fixture can install 6 clips at one time, realizing 6 processing at one time, which greatly improves the processing efficiency, realizes industrialization of enterprises, and improves profit margins.

For further improvement, a 90-width single-slot extension plate is installed between the rectangular base plate and the right angle support. In this way, the setting of the 90-wide single-slot extension plate not only makes the installation of the right angle support firm, but also adjusts the use height of the right angle support by adding or subtracting the number of multi-slot large rectangular supports, which should be determined by the processing equipment, which is very important. Humanize

For further improvement, the two ends of the connecting rod are screwed with fastening bolts for fastening the reinforcement angle. In this way, the position of the connecting rod is limited by using the fastening screw, and there will be no forward and backward movement and shaking. At the same time, there is obvious downward force after the fastening bolt is tightened, so that the overall stability of the fixture is good.

As a further improvement, a support ring sleeved on the connecting rod is installed at the joint between the connecting rod and the first small rectangular support. In this way, the setting of the support ring is used to increase the frictional force generated by the contact between its inner wall and the outer wall of the connecting rod, so that the connecting rod passing through the first small rectangular support has good stability in use and will not be affected by adjustment fixtures or being processed. Stress affects the front and rear displacement and jumping of the connecting rod, which makes the overall stability of the fixture good, and the setting of the support ring can reduce the surface wear of the connecting rod, prolong the service time and reduce the number of replacements.

To further improve, a sliding groove is provided in the middle of the elongated pressing plate, wherein a limit bolt inserted from the outside of the elongating pressing plate to the second small rectangular support is arranged in the sliding groove. In this way, the setting of the sliding groove makes it very simple to adjust the use position of the pressure plate, and the process of opening the chute is simple and low in cost. The limit bolt can limit the use position of the pressure plate so that the pressure plate will not deviate from the normal use position, which is convenient and quick .

The beneficial effects of the utility model are: the structure of the utility model is simple and reasonable, and the use effect is good. The use angle of the positioning reference part installed on it is directly set at 60° through the right angle support, eliminating the need for intermediate adjustment of the workpiece The setting of the positioning reference part enables quick installation on the installation guide block, and the installation position is accurate and the efficiency is very high. The workpiece clamping device can be installed with 6 clamping bars at a time, which can realize mass production. At the same time, the clamping device has low cost and good use effect, and is suitable for a large number of enterprises and is worthy of popularization.
