Description

Technical Field

[0001] This utility model relates to the technical field of vernier caliper production equipment, specifically a clamping and fixing device for caliper grinding. Background Technology

[0002] Vernier calipers are precision measuring tools used to measure dimensions such as length and inner / outer diameters, and are widely used in machining, quality inspection, and other fields. In the caliper manufacturing process, surface grinding is an essential step to ensure the flatness and accuracy of the measuring surfaces. However, traditional caliper grinding fixtures have many shortcomings, especially in angle adjustment and clamping, which often require manual operation, resulting in low efficiency and difficulty in guaranteeing grinding quality.

[0003] Traditional caliper grinding fixtures typically only offer simple clamping functionality and cannot be flexibly adjusted to suit the specific dimensions of the calipers. This results in an insufficiently tight fit between the fixture and the calipers, making them prone to wobbling during grinding and affecting the grinding results. Furthermore, when grinding different angles of the calipers, traditional fixtures often require manual adjustment using external tools, which is cumbersome and lacks precision, failing to meet the demands of high-precision grinding.

[0004] Therefore, in view of the above problems, this utility model proposes a clamping and fixing device for caliper grinding. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] like Figures 1 to 7As shown, this utility model provides a clamping and fixing device for caliper grinding, including a base 1, a support frame 2, an angle adjustment mechanism 3, and a clamping mechanism 4.

[0030] Specifically, the base 1 is used to fix the entire device. It is rectangular plate in shape and has positioning holes 11 and fixing bolts 12 at the bottom for fixing the entire device on the grinding machine. There are four positioning holes 11, which are respectively set at the four corners of the base 1. The number of fixing bolts 12 matches the number of positioning holes 11 and is used to pass through the positioning holes 11 to fix the base 1 on the grinding machine.

[0031] Furthermore, the support frame 2 is connected to the base 1 and is used to support and move the clamping mechanism 4; the support frame 2 is L-shaped and includes a vertical section and a horizontal section. The vertical section is connected to the base 1 and the horizontal section is used to connect the angle adjustment mechanism 3; preferably, there are two support frames 2, which are respectively arranged on both sides of the base 1 to support and maintain the balance and stability of the clamping mechanism 4.

[0032] Furthermore, the angle adjustment mechanism 3 is connected to the horizontal section of the support frame 2 and is used to adjust the angle of the clamping mechanism 4. Specifically, the angle adjustment mechanism 3 includes a motor 31, a worm gear 32, a worm wheel 33, and a rotating disk 34. The motor 31 is connected to the horizontal section of the support frame 2, and its output shaft is connected to the worm gear 32. The worm gear 32 meshes with the worm wheel 33, and the worm wheel 33 is connected to the bottom of the rotating disk 34. When the motor 31 is started, the worm gear 32 drives the worm wheel 33 to rotate, which in turn drives the rotating disk 34 to rotate, thereby realizing the angle adjustment of the clamping mechanism 4.

[0033] To further improve the stability and reliability of angle adjustment, this invention provides a lubrication device 35 at the meshing point of the worm 32 and the worm wheel 33; specifically, as shown... Figure 3 and Figure 4 As shown, the lubrication device 35 includes an oil tank and an oil pipe. The oil tank contains lubricating oil, and the oil pipe connects the oil tank to the meshing point of the worm 32 and the worm wheel 33, and is used to deliver the lubricating oil to the meshing point for lubrication. This can reduce friction and wear during the meshing process and improve the accuracy and smoothness of angle adjustment.

[0034] Furthermore, in order to protect the motor 31 from corrosion by harsh external environments such as dust and water, as a preferred embodiment of this utility model, such as Figure 6 and Figure 7 As shown, the present invention also provides a protective cover 36 on the outside of the motor 31; the protective cover 36 is circular or box-shaped, and can completely cover the motor 31 and fit it tightly; the protective cover 36 is made of corrosion-resistant and wear-resistant materials such as plastic or metal.

[0035] Furthermore, the clamping mechanism 4 is connected to the rotating disk 34 and is used to clamp the calipers; specifically, as shown... Figure 1 and Figure 2 As shown, the clamping mechanism 4 includes a slide rail 41, a slider 42, a clamping plate 43, and an elastic element 44. More specifically, the slide rail 41 is fixedly connected to the rotating disk 34, and its shape is elongated or arc-shaped to guide the movement of the slider 42. The slider 42 is slidably connected to the slide rail 41 and can move along the length of the slide rail 41. Furthermore, the clamping plate 43 is connected to both ends of the slider 42 for clamping the caliper. The clamping plate 43 is L-shaped or U-shaped to hold the caliper. The elastic element 44 is connected between the slider 42 and the rotating disk 34 to provide a restoring force for the slider 42 to press and stabilize the caliper.

[0036] To further improve the clamping effect and stability, the present invention also provides limiting blocks 45 on both sides of the slide rail 41; the shape of the limiting block 45 is preferably rectangular or cylindrical, which can limit the movement range of the slider 42; furthermore, the number of the limiting blocks 45 is two or four, which can be symmetrically arranged on both sides of the slide rail 41; when the slider 42 moves to the end of the slide rail 41, the limiting block 45 can prevent it from continuing to move and play a protective role to prevent it from falling off.

[0037] In addition, to prevent the calipers from slipping or wobbling during the grinding process, such as Figure 2 and Figure 6 As shown, the present invention also provides an anti-slip pad 46 on the inner side of the clamping plate 43; the anti-slip pad 46 is made of rubber, plastic or metal or other materials with anti-slip properties; the anti-slip pad 46 is in the shape of a rectangular sheet or a circular sheet or other shapes that can fit tightly with the clamping plate 43; when the clamping plate 43 clamps the caliper, the anti-slip pad 46 can increase the friction between the clamping plate 43 and the caliper and play an anti-slip role.

[0038] To further improve the stability and load-bearing capacity of the entire device, this utility model also provides a support column 37 below the rotating disk 34; the support column 37 is cylindrical or square and can support the shape of the rotating disk 34; the number of support columns 37 is three or four and can be evenly distributed below the rotating disk 34; the bottom of the support column 37 is connected to the base 1 to ensure that the rotating disk 34 and the clamping mechanism 4 on it can remain stable when bearing the weight of the caliper and the grinding force, and do not tilt or shake.

[0039] While pursuing high-efficiency and precise grinding, this utility model also emphasizes the ease of user operation; therefore, as follows... Figure 3 and Figure 5As shown, a fine-tuning knob 47 is added to the end of the clamping plate 43. The fine-tuning knob 47 is connected to the clamping plate 43 by a threaded connection or lever principle, allowing the operator to fine-tune the clamping force of the clamping plate 43 within a certain range. This design enables the device to adapt to calipers of different sizes, materials and precision, ensuring that the clamping is both stable and does not damage the surface of the calipers.

[0040] Furthermore, considering the wear and aging problems that may be encountered during long-term use, this utility model uses wear-resistant and corrosion-resistant materials for the contact surfaces of key components such as slide rail 41, slider 42, worm 32, and worm wheel 33, and designs an easy-to-disassemble structure to facilitate subsequent maintenance and replacement; this not only extends the service life of the device, but also reduces the user's maintenance costs.

[0041] Safety is also a top priority in this invention. In addition to the motor protection cover 36 mentioned earlier, the entire device also adopts electrical isolation and overload protection design to ensure that the power supply can be cut off in time under abnormal conditions to prevent electrical fires or electric shock accidents. At the same time, all exposed sharp edges and corners have been chamfered to reduce the risk of accidental injury during operation.

[0042] To enhance the user experience, this invention also incorporates intelligent elements; for example, an angle sensor and a speed controller are integrated into the control circuit of the motor 31, which can monitor the progress and speed of angle adjustment in real time and provide feedback to the user through an LED display or a wireless communication module; the user can precisely control the accuracy and speed of angle adjustment based on the information on the display screen to achieve more refined grinding operations.

[0043] In terms of environmental protection and energy conservation, the motor 31 adopts high-efficiency and energy-saving motor technology, which reduces energy consumption and noise; at the same time, the lubricating oil in the lubrication device 35 uses environmentally friendly lubricating oil, which reduces pollution to the environment; in addition, the overall design of the clamping and fixing device is compact, which reduces the use of materials and the generation of waste, in line with the concept of sustainable development.

[0044] In summary, the clamping and fixing device for caliper grinding of this utility model, through innovative angle adjustment mechanism, clamping mechanism and a series of auxiliary designs, not only significantly improves grinding efficiency and quality, but also optimizes user experience, reduces maintenance costs, and takes into account safety and environmental protection.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
