Description

Technical Field

[0001] The utility model relates to the field of measurement auxiliary equipment, and particularly relates to a three-coordinate batch detection fixture. Background Art

[0002] The three-coordinate measuring machine has the functions of automatic detection and batch detection. During the detection process, it is necessary to reasonably place the position of the product and perform effective positioning in order to complete the automatic batch detection through the detection program loop. When performing detection, in order to improve the detection efficiency, the batch detection method is generally adopted. However, when fixing multiple workpieces on the fixture, it is necessary to clamp and fix them one by one, which is time-consuming, and the detection efficiency still needs to be improved. Therefore, it is necessary to manufacture a three-coordinate batch detection fixture that can quickly batch clamp workpieces to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a three-coordinate batch detection fixture to solve the problems mentioned in the background art.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

There are multiple groups of placement grooves above the fixture base, and the multiple groups of placement grooves are evenly arranged in the left-right direction. The rear fixing component is fixed on the rear side of the fixture base, and there are multiple groups of upward protruding first stoppers on the rear fixing component. The multiple groups of first stoppers correspond to the rear sides of the multiple groups of placement grooves one by one. The front fixing component includes a mounting plate, a second stopper, fixing screws, and a first elastic member. The mounting plate is fixed on the front side of the fixture base through the fixing screws. There are multiple groups of second stoppers and they are all fixed above the second stopper. The multiple groups of second stoppers correspond to the front sides of the multiple groups of placement grooves one by one. The first elastic member is fixed on the second stopper and the elastic telescopic end corresponds to the inside of the placement groove. The pressing component includes a pressing plate, a second elastic member, and a third elastic member. The pressing plate corresponds to above the placement groove.

[0018] The present utility model will be further described below with reference to the accompanying drawings:

[0019] As Figures 1 to 4As shown in the figure, a three-coordinate batch detection fixture includes a fixture base 1, a rear fixing component 2, a front fixing component 3, a downward pressing component 4, and a locking component 5. Above the fixture base 1, there are multiple groups of placement grooves 11, and the multiple groups of placement grooves 11 are evenly arranged in the left-right direction. The rear fixing component 2 is fixed to the rear side of the fixture base 1, and there are multiple groups of upward protruding first stoppers 21 on the rear fixing component 2. The multiple groups of first stoppers 21 correspond to the rear sides of the multiple groups of placement grooves 11 one by one. The front fixing component 3 includes a mounting plate 31, a second stopper 32, fixing screws 33, and a first elastic component 34. The mounting plate 31 is fixed to the front side of the fixture base 1 through the fixing screws 33. There are multiple groups of second stoppers 32, and they are all fixed above the second stopper 32. The multiple groups of second stoppers 32 correspond to the front sides of the multiple groups of placement grooves 11 one by one. The first elastic component 34 is fixed to the second stopper 32, and its elastic telescopic end corresponds to the inside of the placement groove 11. The downward pressing component 4 includes a pressing plate 41, a second elastic component 42, and a third elastic component 43. The pressing plate 41 corresponds to above the placement groove 11. The second elastic component 42 is fixed to the pressing plate 41, and its elastic telescopic end faces downward. There are multiple groups of second elastic components 42, and they correspond to the multiple groups of placement grooves 11 one by one. The third elastic component 43 is fixed to the left and right ends of the pressing plate 41, and its elastic telescopic end faces outward. The locking component 5 includes a locking plate 51 and a torsion spring. The middle of the locking plate 51 is installed at the end of the fixture base 1 through the torsion spring. There is a locking hole 511 at the upper end of the locking plate 51. The elastic telescopic end of the third elastic component 43 passes through the locking hole 511. There are two groups of locking components 5, and they respectively correspond to the left and right sides of the fixture base 1.

[0020] When installing the workpiece, place the workpieces one by one into the placement grooves 11, and then place the pressing plate 41 above all the workpieces. Press down the pressing plate 41 to apply pressure to the workpieces. The front end of the workpiece compresses the elastic end of the first elastic component 34 in the front fixing component 3, so that the workpiece can be completely placed in the placement groove 11. At the same time, during the downward pressing process of the pressing plate 41, the telescopic end of the third elastic component 43 is compressed and then pops out. The telescopic end of the third elastic component 43 is inserted into the locking hole 511 of the locking plate 51. At this time, the second elastic component 42 is also in a compressed state. Under the action of the locking component 5, the position of the downward pressing component 4 is fixed, and the position of the workpiece is fixed, thereby quickly realizing the batch installation and positioning of multiple groups of workpieces and improving the detection efficiency.

[0021] There are multiple groups of upward protruding limit blocks 12 on the fixture base 1. Two adjacent limit blocks 12 correspond to the left and right sides of a group of placement grooves 11.

[0022] During detection, it can prevent the workpiece from shifting in the left-right direction and improve the detection efficiency.

[0023] On the upper left and right sides of the limit block 12, there are round corners, which can facilitate the guiding and placement of the workpiece.

[0024] The lower end of the locking plate 51 is provided with a pressing portion 512 that bends outward. After the detection is completed, pressing the pressing portion 512 of the locking plate 51 inward can cause the upper end of the locking plate 51 to move outward, so that the locking hole 511 is disengaged from the third elastic member 43, realizing the unlocking of the pressing plate 41, and thus the measured workpiece can be taken out.

[0025] The first elastic member 34, the second elastic member 42, and the third elastic member 43 all adopt ball head set screws.

[0026] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
