Description

Technical Field

[0001] This utility model relates to the field of measuring tools, specifically a tool for measuring the flatness of a grinding disc. Background Technology

[0002] In the processing of crystal materials, grinding is often required. Grinding is a step between cutting and polishing, aimed at removing cutting marks and thinning the wafer. Cast iron grinding discs are typically used. During grinding, the cast iron grinding discs deform, especially when grinding hard and brittle materials such as silicon carbide and sapphire. To ensure the flatness of the upper and lower discs remains within a certain range, the flatness of the grinding disc surface needs to be measured daily to check whether it meets the flatness requirements.

[0003] Currently, the method for measuring the flatness of the upper plate of a grinding wheel is as follows: first, wipe the plate surface clean with a cloth and then dry it with an air gun. The measurement requires three people to operate simultaneously: two people lift the flatness measuring instrument and place it firmly against the upper plate surface, while one person uses a feeler gauge to measure. Because the flatness measuring instrument is heavy, lifting it is laborious, and uneven force can affect measurement accuracy, posing a safety hazard to wafer grinding and wasting manpower. Therefore, a grinding wheel flatness measuring tool is proposed to solve the aforementioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a grinding disc flatness measuring tool to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a grinding disc flatness measuring tool, including a grinding disc body, a first fixing mechanism is provided on the grinding disc body, a flatness detector is provided on the first fixing mechanism, and a second fixing mechanism is provided on the first fixing mechanism;

[0006] The first fixing mechanism includes: a base, which is located at the bottom of the grinding disc body and is U-shaped; a flatness tester is located inside the base, with its top fitting against the bottom of the grinding disc body; a fixing seat connected to the front of the base, which is C-shaped; a lead screw threaded to the top of the fixing seat; a clamping plate rotatably connected to the bottom of the lead screw via a bearing; and a knob connected to the top of the lead screw. Rotating the knob causes the lead screw to rotate and move vertically, which in turn causes the clamping plate to move up and down. Thus, the base and fixing seat are fixed to the grinding disc body, and the top of the flatness tester is tightly fitted against the bottom of the grinding disc body. A feeler gauge of appropriate thickness is then inserted for measurement. Fixing and testing can be completed without the need for multiple people, solving the problem of the laborious manual lifting of the flatness tester in traditional methods and improving operational convenience and measurement accuracy.

[0007] Preferably, there are two of each of the fixed base, lead screw, clamping plate, and knob, which are arranged opposite each other on the front and rear sides of the base. The grinding disc body is located in the inner cavity of the two fixed bases, which can simultaneously clamp the grinding disc body from both sides, avoiding the flatness tester from tilting due to unilateral force.

[0008] Preferably, the second fixing mechanism includes: two fixing plates, which are fixedly connected to the bottom of the base. A bidirectional threaded rod is rotatably connected between the two fixing plates via a bearing. Clamping plates are threaded to the reverse threads of the bidirectional threaded rod. The opposing surfaces of the two clamping plates abut against the front and rear sides of the flatness tester. Rubber pads are adhered to the opposing surfaces of the two clamping plates. The bidirectional threaded rod rotates to drive the two clamping plates to move closer or further away synchronously, quickly clamping the flatness tester. This facilitates the installation, fixing, and disassembly of the flatness tester. The rubber pads on the surface of the clamping plates increase friction to prevent the tester from sliding and avoid damage to the equipment caused by hard contact.

[0009] Preferably, the front end of the bidirectional threaded rod passes through the fixed plate and extends forward. The extended end of the bidirectional threaded rod is connected to a handwheel. By rotating the handwheel, the bidirectional threaded rod can be directly driven to rotate. The clamping and releasing of the flatness tester can be completed without additional tools. It can be operated by a single person, which significantly reduces labor costs.

[0010] Preferably, the bottom of the base is provided with a sliding hole, which is rectangular in shape. The outer walls of the two clamping plates are slidably connected to the inner walls of the sliding hole, and the clamping plates are limited by the sliding hole, so that the rotational movement of the clamping plates is transformed into horizontal movement back and forth.

[0011] Preferably, the flatness tester has an air inlet channel on its right side and a plurality of air outlets at equal intervals on its top, which are connected to the air inlet channel. Gas enters through the air inlet channel and exits through the air outlets, cleaning the abrasive at the bottom of the grinding disc body, preventing impurities from affecting the fit between the flatness tester and the grinding disc, ensuring that the measurement results are not interfered with by foreign objects, improving the detection accuracy.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This grinding disc flatness measuring tool rotates a knob to drive a lead screw to rotate and move vertically. The lead screw drives a clamping plate to move up and down, thereby fixing the base and fixing seat to the grinding disc body and ensuring that the top of the flatness tester fits tightly against the bottom of the grinding disc body. Then, a feeler gauge of appropriate thickness is inserted for measurement. Fixing and testing can be completed without the need for multiple people to cooperate, solving the problem of the laboriousness of manually lifting the flatness tester in traditional methods, and improving the convenience of operation and measurement accuracy.

[0014] 2. This grinding disc flatness measuring tool drives a bidirectional threaded rod to rotate by turning a handwheel. The rotation of the bidirectional threaded rod drives two clamping plates to move closer or further apart synchronously, quickly clamping the flatness tester. This facilitates the installation, fixing, and disassembly of the flatness tester. The rubber pads on the surface of the clamping plates increase friction to prevent the tester from sliding and avoid damage to the equipment caused by hard contact. Attached Figure Description

[0020] 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0024] Please see Figure 1-4 One embodiment of this utility model is as follows: a grinding disc flatness measuring tool, including a grinding disc body 1, a first fixing mechanism 2 disposed on the grinding disc body 1, a flatness detector 3 disposed on the first fixing mechanism 2, and a second fixing mechanism 4 disposed on the first fixing mechanism 2; the first fixing mechanism 2 includes: a base 21, which is disposed at the bottom of the grinding disc body 1 and is U-shaped; the flatness detector 3 is disposed in the inner cavity of the base 21, with the top of the flatness detector 3 fitting against the bottom of the grinding disc body 1; a fixing seat 22 is connected to the front of the base 21 and is C-shaped; a lead screw 23 is threadedly connected to the top of the fixing seat 22; the bottom end of the lead screw 23 is rotatably connected to a clamping plate 24 via a bearing; and the top end of the lead screw 23 is connected to... A knob 25 is connected. Rotating the knob 25 drives the lead screw 23 to rotate and move vertically. The lead screw 23 drives the clamping plate 24 to move up and down, thereby fixing the base 21 and the fixed seat 22 onto the grinding disc body 1, and making the top of the flatness tester 3 fit tightly against the bottom of the grinding disc body 1. Then, a feeler gauge of the appropriate thickness is inserted for measurement. Fixing and testing can be completed without the need for multiple people to cooperate, which solves the problem of the laboriousness of manually lifting the flatness tester 3 in the traditional way, and improves the convenience of operation and measurement accuracy. There are two of each of the fixed seat 22, lead screw 23, clamping plate 24 and knob 25, which are arranged opposite each other on the front and rear sides of the base 21. The grinding disc body 1 is located in the inner cavity of the two fixed seats 22, which can clamp the grinding disc body 1 simultaneously from both sides, avoiding the flatness tester 3 tilting due to unilateral force.

[0025] The flatness tester 3 has an air inlet channel 5 on its right side and several air outlets 6 at equal intervals on its top, which are connected to the air inlet channel 5. Gas enters through the air inlet channel 5 and is ejected from the air outlets 6, cleaning the abrasive at the bottom of the grinding disc body 1. This prevents impurities from affecting the fit between the flatness tester 3 and the grinding disc, ensuring that the measurement results are not interfered with by foreign objects, thus improving the detection accuracy.

[0026] Working principle: Rotating the knob 25 drives the lead screw 23 to rotate and move vertically. The lead screw 23 drives the clamping plate 24 to move up and down, thereby fixing the base 21 and the fixed seat 22 on the grinding disc body 1, and bringing the top of the flatness tester 3 close to the bottom of the grinding disc body 1. Then, the compressed gas is turned on, and the gas enters through the air inlet channel 5 and is ejected from the air outlet 6 to blow away the abrasive at the bottom of the grinding disc body 1. Continue to rotate the lead screw 23 to fix the fixed seat 22 firmly, and make the top of the flatness tester 3 fit tightly against the bottom of the grinding disc body 1. Then, insert a feeler gauge of the appropriate thickness for measurement. If the feeler gauge cannot be pulled out, the disc surface meets the requirements; otherwise, the disc needs to be repaired.

[0027] Please see Figure 1-4 Based on the above embodiments, in another embodiment of this utility model, the second fixing mechanism 4 includes: two fixing plates 41, which are fixedly connected to the bottom of the base 21. A bidirectional threaded rod 42 is rotatably connected between the two fixing plates 41 via a bearing. The front end of the bidirectional threaded rod 42 passes through the fixing plate 41 and extends forward. A handwheel 44 is connected to the extended end of the bidirectional threaded rod 42. Rotating the handwheel 44 directly drives the bidirectional threaded rod 42 to rotate, allowing the flatness detector 3 to be clamped and released without additional tools. This can be operated by a single person, significantly reducing labor costs. Clamping plates 43 are threadedly connected to the reverse threads of the bidirectional threaded rod 42. The bottom of the base 21... The device has a rectangular sliding hole 45. The outer walls of the two clamping plates 43 are slidably connected to the inner walls of the sliding hole 45. The sliding hole 45 limits the clamping plates 43, so that the rotational movement of the clamping plates 43 is converted into horizontal movement. The opposite surfaces of the two clamping plates 43 abut against the front and rear sides of the flatness tester 3. Rubber pads are glued to the opposite surfaces of the two clamping plates 43. The two clamping plates 43 are driven to move synchronously closer or further away by the rotation of the bidirectional threaded rod 42, which quickly clamps the flatness tester 3, making it convenient for the installation, fixing and disassembly of the flatness tester 3. The rubber pads on the surface of the clamping plates 43 increase the friction to prevent the tester from sliding and avoid damage to the equipment caused by hard contact.

[0028] Working principle: By rotating the handwheel 44, the bidirectional threaded rod 42 is driven to rotate. The rotation of the bidirectional threaded rod 42 drives the two clamping plates 43 to move closer or further apart synchronously, quickly clamping the flatness tester 3. This facilitates the installation, fixing, and disassembly of the flatness tester 3. The rubber pads on the surface of the clamping plates 43 increase friction to prevent the tester from sliding and avoid damage to the equipment caused by hard contact.

[0029] It is worth noting that the flatness tester 3 in the above embodiments is a commonly used device in the prior art. The model and other specifications can be customized according to actual usage requirements. Furthermore, the power supply interface of the electrical equipment in this utility model is connected to the power supply system through a switch (not shown in the figure) and wires (not shown in the figure) to achieve control over it. The circuit control, specific composition and principle involved are all prior art and are well known in the current field. They are clear to those skilled in the art, so they will not be described in detail here.

[0030] This utility model provides a tool for measuring the flatness of a grinding disc. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
