Description

Technical Field

[0001] This utility model relates to the field of precision hardware inspection, specifically a clamping base for precision hardware inspection. Background Technology

[0002] Precision hardware is a sub-sector within the hardware industry that demands stringent processing precision, with its core characteristic being the control of product tolerances within 0.05mm. This type of processing encompasses precision plastic hardware, stamped hardware, and turned hardware, achieved through processes such as material cutting, precision forming, surface treatment (grinding / electroplating / painting), and assembly. As industrial supporting tools and semi-finished products, its applications cover fundamental fields such as electronics, watchmaking, and aerospace, and extend to industries such as new energy and automobile manufacturing. Typically, after the precision hardware parts are processed, workers need to inspect them, which requires the use of clamping bases to hold and fix the precision hardware parts in place.

[0003] However, the existing clamping bases for precision hardware inspection have the following defects during operation: the same clamping base can only clamp and fix the same type of precision hardware. When clamping different types of precision hardware, the operator needs to change the clamping base. There is a lack of clamping mechanisms that can be compatible with different types of precision hardware, which means that the operator needs to change the corresponding clamping base after each inspection of a type of precision hardware. Utility Model Content

[0004] The present invention aims to provide a clamping base for the inspection of precision hardware parts, mainly to solve the technical problem that the existing technology lacks a clamping mechanism that can be compatible with different types of precision hardware parts, which means that the staff needs to change the corresponding clamping base after each inspection of a type of precision hardware part.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A clamping base for inspecting precision hardware parts includes a base. First screws are provided on both sides of the top of the base. One end of each first screw is connected to a fixed plate via a bearing seat. An arc-shaped groove is formed on one side of the fixed plate, and a baffle is slidably disposed on one side of the fixed plate near the arc-shaped groove. A blocking mechanism that restricts the baffle is rotatably disposed on the top of the fixed plate. Extension plates are fixedly connected to both sides of the fixed plate. Rotating rods are rotatably connected to the top and bottom of the inner walls of the extension plates, respectively. A second screw is rotatably disposed between the two rotating rods. A cam is fixedly connected to the top of the rotating rod that passes through the top of the extension plate. A limiting mechanism that engages with the cam is slidably disposed on the top of the fixed plate. One end of the second screw is connected to a connecting plate via a bearing seat. A rotating frame is rotatably connected to one end of the connecting plate, and a rubber pad is adhered to one side of the rotating frame.

[0007] The working principle and beneficial effects of this utility model:

[0008] 1. Working Principle: The baffles facilitate clamping and fixing square parts when the two first screws drive the two baffles closer together. The baffles rotate 90 degrees upwards, releasing the restriction on the baffles and allowing them to be pulled out of the fixing plate. The two arc-shaped grooves facilitate clamping and fixing round parts. Pulling the second screw causes it to rotate laterally and drive the connecting plate to move. Since the rotating frame can rotate at one end of the connecting plate, it can tilt the rubber pad to clamp and fix irregularly shaped parts. In addition, the limiting mechanism moves downwards and is fitted onto the outer wall of the cam, thus limiting and fixing the rotation angle of the second screw.

[0009] 2. Beneficial effects:

[0010] (1) By limiting the bottom end of the plate to contact the top end of the baffle, it is convenient to adjust the position of the baffle by the first screw, so as to clamp and fix the position of the square part. When the baffle is pulled out from the slot, the arc groove is convenient to clamp and fix the position of the round part. The rotating rod is convenient to adjust the lateral rotation angle of the second screw. The second screw can move the position of the rotating frame, so that the rotating frame can drive the rubber pad to clamp and fix the position of the irregular part at an angle. The pressure plate drives the limiting groove to be sleeved on the outside of the cam, so as to limit and fix the rotation angle of the second screw.

[0011] Preferably, support plates are fixedly connected to both sides of the top of the base, and the outer walls of the two first screws are threaded through the two support plates on both sides respectively; rotating the first screws causes the first screws to move on one side of the support plates, thereby moving the first screws closer to the center of the base. At this time, the two first screws drive the two fixed plates to move closer to each other, which facilitates the subsequent clamping and fixing of the square parts.

[0012] Preferably, the top of the fixing plate has a slot with a connecting arc-shaped groove, and the baffle is slidably connected inside the slot; when the baffle is pulled upward, so that the baffle is pulled out from inside the slot, the position of the circular part is easily clamped and fixed due to the action of the two arc-shaped grooves.

[0013] Preferably, the blocking mechanism includes a stud and a limiting plate. The bottom end of the stud is fixedly connected to the top end of the fixed plate, and the limiting plate is threadedly connected to the outer wall of the stud. When the limiting plate is rotated upward by 90 degrees, the limiting plate rotates upward on the outer wall of the stud. At this time, the limiting plate separates from the baffle, thereby releasing the restriction on the baffle.

[0014] Preferably, one end of the extension plate is provided with an installation groove, and a threaded cylinder is provided inside the installation groove. One end of each of the two rotating rods is fixedly connected to the top and bottom of the outer wall of the threaded cylinder, respectively, so that when the second screw is pulled, the second screw can drive the threaded cylinder to rotate between the two rotating rods, thereby facilitating the adjustment of the lateral rotation angle of the second screw.

[0015] Preferably, the outer wall of one of the rotating rods penetrates the top of the extension plate, and the second screw is connected to the inside of the threaded cylinder. By rotating the second screw, the second screw can be moved inside the threaded cylinder, thereby facilitating the adjustment of the distance between the two second screws.

[0016] Preferably, the limiting mechanism includes a support rod, a slider, a pressure plate, and a limiting groove. The bottom end of the support rod is fixedly connected to the top end of the extension plate. A slider is slidably connected to the outer wall of the support rod. A pressure plate is fixedly connected to one end of the slider. A limiting groove is provided at the bottom end of the pressure plate. Pulling the pressure plate upward causes the pressure plate to drive the slider to slide on the outer wall of the support rod, causing the pressure plate to drive the limiting groove to separate from the cam, thereby releasing the restriction on one rotating rod.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, a clamping base for testing precision hardware parts includes a base 1. A first screw 3 is provided on both sides of the top of the base 1. A support plate 2 is fixedly connected to both sides of the top of the base 1. The outer walls of the two first screws 3 pass through the two support plates 2 respectively by threads. Rotating the first screws 3 causes the first screws 3 to move on one side of the support plate 2, thereby moving the first screws 3 closer to the center of the base 1.

[0024] One end of the first screw 3 is connected to a fixing plate 4 via a bearing seat. An arc-shaped groove 5 is provided on one side of the fixing plate 4. A baffle 7 is slidably provided on one side of the fixing plate 4 near the arc-shaped groove 5. A slot 6 communicating with the arc-shaped groove 5 is provided at the top of the fixing plate 4. The baffle 7 is slidably connected inside the slot 6. The two first screws 3 respectively drive the two fixing plates 4 to move closer to each other, so as to facilitate the clamping and fixing of the position of the square part. When the baffle 7 is pulled upward, it is easy to clamp and fix the position of the round part due to the action of the two arc-shaped grooves 5.

[0025] The top of the fixed plate 4 is rotatably equipped with a limiting baffle 7. The limiting mechanism includes a stud 8 and a limiting plate 9. The bottom end of the stud 8 is fixedly connected to the top of the fixed plate 4. The limiting plate 9 is threadedly connected to the outer wall of the stud 8. When the limiting plate 9 is rotated upward by 90 degrees, the limiting plate 9 rotates upward on the outer wall of the stud 8. At this time, the limiting plate 9 separates from the baffle 7, thereby releasing the restriction on the baffle 7.

[0026] An extension plate 10 is fixedly connected to both sides of the fixed plate 4. A rotating rod 12 is rotatably connected to the top and bottom of the inner wall of the extension plate 10. A second screw 14 is rotatably mounted between the two rotating rods 12. A cam 18 is fixedly connected to the top of the rotating rod 12 that passes through the top of the extension plate 10. An installation groove 11 is provided at one end of the extension plate 10, and a threaded cylinder 13 is installed inside the installation groove 11. One end of each of the two rotating rods 12 is fixedly connected to the top and bottom of the outer wall of the threaded cylinder 13, respectively. The outer wall of one rotating rod 12 passes through the top of the extension plate 10. The second screw 14 is connected inside the threaded cylinder 13. One end of the second screw 14 is connected to a bearing seat. A connecting plate 15 is rotatably connected to a rotating frame 16 at one end. A rubber pad 17 is adhered to one side of the rotating frame 16. When the second screw 14 is pulled, the second screw 14 drives the threaded cylinder 13 to rotate between the two rotating rods 12, thereby adjusting the lateral rotation angle of the second screw 14. Rotating the second screw 14 causes the two second screws 14 to move inside the threaded cylinder 13 respectively. At this time, the two second screws 14 drive the two connecting plates 15 to move respectively. Since the rotating frame 16 can rotate freely laterally at one end of the connecting plate 15, it is convenient for the rotating frame 16 to drive the rubber pad 17 to clamp and fix the position of the irregular part at an angle.

[0027] The top of the fixed plate 4 is slidably provided with a limiting mechanism that engages with the cam 18. The limiting mechanism includes a support rod 19, a slider 20, a pressure plate 21, and a limiting groove 22. The bottom end of the support rod 19 is fixedly connected to the top end of the extension plate 10. The slider 20 is slidably connected to the outer wall of the support rod 19. One end of the slider 20 is fixedly connected to the pressure plate 21. The bottom end of the pressure plate 21 has a limiting groove 22. After adjustment, the pressure plate 21 is pulled down so that the pressure plate 21 drives the limiting groove 22 to fit on the outside of the adjusted cam 18, thereby limiting the position of the cam 18, which facilitates the limiting and fixing of the rotation angle of the second screw 14.

[0028] As described above, the specific implementation of this utility model is as follows: The first screw 3 is rotated, causing it to move on one side of the support plate 2, thus bringing it closer to the center of the base 1. At this time, the two first screws 3 respectively drive the two fixing plates 4 to move closer to each other. The bottom end of the limiting plate 9 contacts the top end of the baffle 7, thus restricting the baffle 7 inside the slot 6, facilitating the clamping and fixing of the square part. Then, the limiting plate 9 is rotated upwards by ninety degrees, causing it to rotate upwards on the outer wall of the stud 8. At this time, the limiting plate 9 separates from the baffle 7, thus releasing the restriction on the baffle 7. The baffle 7 is pulled upwards, causing it to be pulled out of the slot 6. Due to the action of the two arc-shaped grooves 5, the position of the round part is easily clamped and fixed. Additionally, the pressure plate 21 is pulled upwards, causing the pressure plate 21 to drive the slider 20 to slide on the outer wall of the support rod 19, thus... The pressure plate 21 causes the limiting groove 22 to separate from the cam 18, thereby releasing the restriction on one of the rotating rods 12. When the second screw 14 is pulled, the second screw 14 drives the threaded cylinder 13 to rotate between the two rotating rods 12, thereby adjusting the lateral rotation angle of the second screw 14. Rotating the second screw 14 causes the two second screws 14 to move inside the threaded cylinder 13 respectively. At this time, the two second screws 14 drive the two connecting plates 15 to move respectively. Since the rotating frame 16 can rotate freely laterally at one end of the connecting plate 15, it is convenient for the rotating frame 16 to drive the rubber pad 17 to tilt and clamp and fix the position of the irregular part. After the adjustment is completed, the pressure plate 21 is pulled down, so that the pressure plate 21 drives the limiting groove 22 to be sleeved on the outside of the adjusted cam 18, thereby restricting the position of the cam 18, which facilitates the restriction and fixation of the rotation angle of the second screw 14.

[0029] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
