Description

Technical Field

[0001] This utility model relates to a high-precision positioning device and testing equipment for testing equipment. Background Technology

[0002] Test machines are used to test the performance of components. During operation, the test machine is located inside a test cabinet and performs testing. When the test machine needs maintenance, it must be removed from the test cabinet for inspection or dismantled from the test cabinet for return to the factory for repair. Currently, quick-change test cabinets have emerged in the market. For example, the utility model patent CN219925815U, published on October 31, 2023, discloses a quick-change high-precision positioning mechanism. In use, the test machine, fixed to the fixture plate, is pushed along the X-axis guide side plate to the stop block, and the operator then tightens the positioning screws to quickly position the positioning holes on the fixture plate.

[0003] However, this structure has the following two problems:

[0004] Firstly, because the positioning screws are located on both sides of the upper surface of a pair of X-axis guide side plates, and multiple testing machines in some testing cabinets are too close together with limited space, operators need to reach between every two testing machines to lock the four screws into the positioning holes on the fixture plate, which is inconvenient.

[0005] Secondly, if the testing machine needs to be overhauled, it needs to be pulled out of the testing cabinet and removed from the fixture plate. After removal, it needs to be reinstalled. This structure cannot be quickly and accurately reset into the testing cabinet. Utility Model Content

[0006] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a high-precision positioning device and testing equipment for testing equipment that is easy to operate and can be quickly and accurately reset into the testing cabinet after the testing machine is disassembled.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-precision positioning device for a testing machine, comprising a fixture plate for mounting the testing machine, the front and rear ends of which are detachably mounted on a sliding plate via quick-release pins; telescopic guide rails are respectively locked to both sides of the sliding plate, and the telescopic guide rails are mounted on the two inner side walls of the testing cabinet; a front stop and a rear stop are respectively provided at the front and rear ends of the sliding plate, and a fixed stop lower than the sliding plate is fixedly provided at the rear end of the inner bottom plate of the testing cabinet, with corresponding positioning bolt holes on the fixed stop and the rear stop; when the sliding plate slides backward along the telescopic guide rails out of the testing cabinet, the fixed stop abuts against the front stop; when the sliding plate slides forward along the telescopic guide rails into the testing cabinet, the fixed stop abuts against the rear stop and is fixed by locking with positioning bolts.

[0008] Preferably, the jig plate has blocking and positioning blocks fixedly installed at its front and rear ends, and side rails on both sides. The testing machine is limited within the blocking and positioning blocks and side rails. Each blocking and positioning block is provided with a locking bolt for abutting against the front and rear end faces of the testing machine. The testing machine's position is limited by two blocking and positioning blocks and side rails, and the locking bolts ensure the accuracy of the testing machine's position.

[0009] Preferably, the maximum width of the skateboard is greater than the width of the jig plate, the jig plate is located in the middle of the jig plate, and the side guard is set on the skateboard not covered by the jig plate and is higher than the skateboard.

[0010] Preferably, each side rail has a guide slope on its inner sidewall. This serves to guide the testing machine, preventing collisions caused by misalignment of the testing machine with the side rail, and also facilitates the installation of the testing machine.

[0011] Preferably, the jig plate and the slide plate are provided with pin holes at their front and rear ends, and quick-release pins are inserted into the corresponding upper and lower pin holes.

[0012] Preferably, a connecting strip is fixed to the bottom of the slide plate, and the connecting strip is locked to the telescopic guide rail. The lower end of the quick-release pin extends out of the slide plate, and a clearance groove is provided on the connecting strip. The lower end of the quick-release pin is located in the clearance groove. The clearance groove creates clearance space, allowing quick-release pins of various lengths to be used, thus improving applicability.

[0013] Preferably, the slide plate is provided with a limit stop to limit the side of the fixture plate. The limit stop provides a limit to the fixture plate, which facilitates the installation of the quick-connect pin.

[0014] Preferably, a slot is provided on the rear end face of the fixed block, and the rear block can be inserted into the slot.

[0015] A testing machine includes a testing cabinet, which has multiple testing machine mounting positions. A testing machine is mounted on each of the testing machine mounting positions using the aforementioned high-precision positioning device. A rear sealing plate is hinged to the rear side of each testing machine mounting position.

[0016] Preferably, the upper end of the rear cover is hinged to the test cabinet. This upper hinge allows the rear cover to be opened upwards without affecting the maintenance of the test machine.

[0017] The advantages of this utility model for a high-precision positioning device and testing equipment are:

[0018] Firstly, the front stop, rear stop, fixed stop, and quick-release pins are distributed on the front and rear sides. When the testing machine slides out of the testing cabinet with the slide plate, the front stop and fixed stop provide a limit to the slide plate, preventing it from continuing to slide backward and out of the testing cabinet. The rear stop and fixed stop are used to position the slide plate for reset, and the positioning bolts and positioning bolt holes are used to lock the reset position. This eliminates the need for screws and positioning holes on both sides for locking. Even if the space between two adjacent testing machines is small, the positioning bolts and positioning bolt holes are located at the rear of the testing cabinet, not on the sides, which facilitates accurate positioning.

[0019] Secondly, when the testing machine needs to be overhauled, first pull the testing machine out of the slide. Due to the action of the quick-release pin, the testing machine and the fixture plate below will slide out with the slide. After removing the quick-release pin, remove the fixture plate and the testing machine together for repair. After the repair is completed, put the fixture plate and the testing machine back into the slide. Use the quick-release pin to quickly position the fixture plate and the slide, so that the testing machine can quickly be positioned back to its original position. Attached Figure Description

[0033] Example 1

[0034] See Figure 1-8 As shown, this embodiment discloses a high-precision positioning device for testing equipment, comprising:

[0035] The fixture plate 1 is used to install the testing machine 2. The front and rear ends of the fixture plate 1 are respectively fixedly installed with blocking and positioning blocks 18. The two sides of the fixture plate 1 have side bars 11. The testing machine 2 is limited within the blocking and positioning blocks 18 and the side bars 11. Each blocking and positioning block 18 is provided with locking bolts for abutting the front and rear end faces of the testing machine 2, so as to fix the testing machine 2 within the blocking and positioning blocks 18 and the side bars 11.

[0036] The front and rear ends of the jig plate 1 are detachably mounted on the slide plate 4 via quick-release pins 3. The jig plate 1 and the slide plate 4 are provided with pin holes 13 at their respective front and rear ends, and quick-release pins 3 are inserted into the corresponding upper and lower pin holes 13.

[0037] Telescopic guide rails 5 are locked to both sides of the slide plate 4. The telescopic guide rails 5 are installed on the two inner side walls of the test cabinet 6 to enable the slide plate 4 to slide back and forth.

[0038] The front and rear ends of the slide plate 4 are respectively provided with a front stop 7 and a rear stop 8. The rear end of the inner bottom plate 21 of the test cabinet 6 is fixedly provided with a fixed stop 9 lower than the slide plate 4. The fixed stop 9 and the rear stop 8 are provided with corresponding positioning bolt holes 10. When the slide plate 4 slides backward out of the test cabinet 6 along the telescopic guide rail 5, the front end face of the fixed stop 9 abuts against the front stop 7 to prevent the slide plate 4 (i.e., the fixture plate 1) from continuing to slide out of the test cabinet 6. When the slide plate 4 slides forward back into the test cabinet 6 along the telescopic guide rail 5, the rear end face of the fixed stop 9 abuts against the rear stop 8 to provide a limiting function, and is locked and fixed by the positioning bolts passing through the positioning bolt holes 10.

[0039] The maximum width of the skateboard 4 is greater than the width of the jig plate 1. The jig plate 1 is located in the middle of the jig plate 1. The side guard strip 11 is set on the skateboard 4 that is not covered by the jig plate 1 and is higher than the skateboard 4.

[0040] Each side bar 11 has a guide slope 12 on its inner side wall.

[0041] A connecting strip 14 is fixed to the bottom of the slide plate 4. The connecting strip 14 is locked and fixed to the telescopic guide rail 5. The lower end of the quick-release pin 3 extends out of the slide plate 4. A clearance groove 15 is provided on the connecting strip 14. The lower end of the quick-release pin 3 is located in the clearance groove 15.

[0042] A limit stop 19 is provided on the slide plate 4 to limit the side of the fixture plate 1. Figure 3 As shown, in this embodiment, the limiting block 19 is only provided on the front side of the fixture plate 1 to limit the front side of the fixture plate 1.

[0043] A slot 20 is provided on the rear end face of the fixed block 9, and the rear block 8 can be inserted into the slot 20.

[0044] Example 2

[0045] like Figure 9 , Figure 10 As shown, a testing device includes a testing cabinet 6, which has multiple testing machine mounting positions 16. Each testing machine mounting position 16 is equipped with a high-precision positioning device as described in Embodiment 1, and a rear sealing plate 17 is hinged to the rear side of each testing machine mounting position 16. As shown, the upper end of the rear sealing plate 17 is hinged to the testing cabinet 6.

[0046] The working principle of Example 2 is as follows:

[0047] When it is necessary to inspect any of the test machine 2s in the test machine mounting position 16, the corresponding rear cover plate 17 needs to be opened. The rear cover plate 17 is rotated upward to open, and the operator pulls the slide plate 4 out from the rear side of the test machine cabinet 6 until the front stop 7 hits the front end face of the fixed stop 9. At this time, the test machine 2 can be inspected on the slide plate 4. If the test machine 2 needs to be removed and returned to the factory for overhaul, the quick pin 3 is removed, and the test machine 2 is removed from the slide plate 4 along with the fixture plate 1. If the test machine 2 needs to be removed from the fixture plate 1, the locking bolt is loosened, and the test machine 2 can be removed from the fixture plate 1.

[0048] After the inspection is completed, the testing machine 2 is placed inside the blocking positioning block 18 and the side rails 11 of the fixture plate 1, and then locked with locking bolts. After locking, the fixture plate 1 is placed along the limiting block 19 and the side rails 11 on both sides. The cooperation of the limiting block 19 and the side rails 11 on both sides positions the fixture plate 1. Then, the quick-release pins 3 are inserted into the four sets of pin holes 13 corresponding to the fixture plate 1 and the slide plate 4. At this time, the testing machine 2 and the fixture plate 1 are fixed on the slide plate 4.

[0049] Next, the operator pushes the slide plate 4 into the test cabinet 6, and the test machine 2 and the fixture plate 1 are then pushed into the test cabinet 6. The rear stop 8 hits the rear end face of the fixed stop 9 and reaches the limit position. Then, it is locked in place by the positioning bolts. At this time, the test machine 2 returns to the test position precisely.

[0050] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
