Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of rough grinding tooling, and particularly relates to a large flat plate rough grinding support. BACKGROUND

[0002] There is a kind of large flat plate workpiece in workpiece processed by factory, such as liquid cooling plate, and a plurality of liquid cooling flow channels or liquid cooling cavities are arranged in the interior. Since the liquid cooling flow channel or liquid cooling cavity is not good to process in the interior, the liquid cooling plate is divided into upper and lower two split plates along the center line of the liquid cooling flow channel or liquid cooling cavity for processing, so that the liquid cooling flow channel or liquid cooling cavity becomes a surface groove and is easier to process, and after processing, the upper and lower two split plates are combined into one by brazing.

[0003] However, if the flatness of the opposite surfaces of the upper and lower two split plates cannot meet the requirement, the contact surfaces of the upper and lower two split plates have convex points, and the two cannot be completely attached together, there will be a gap, and the heat-conducting medium in the liquid cooling flow channel or liquid cooling cavity will penetrate into the gap, affecting the service life, even if the heat-conducting medium does not penetrate into the gap, the gap also affects the heat-conducting effect of the whole liquid cooling plate. Therefore, the opposite surfaces of the upper and lower two split plates need to be ground before brazing to meet the flatness requirement.

[0004] However, it is found in practice that when the opposite surfaces of the upper and lower two split plates form relatively large convex points in machining, the processing time of the grinding process is obviously lengthened, and the production cost is obviously increased. When the grinding allowance is reduced by manual rough grinding by using an angle grinder or a pneumatic grinding head and the like, it is difficult to control, and the workpiece is easily scrapped, which is not worth the cost. UTILITY MODEL CONTENTS

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art, and provide a large flat plate rough grinding support for solving the technical problem that it is difficult to control the grinding amount and grinding angle when manually rough grinding a large flat plate workpiece, resulting in workpiece scrapping and not worth the cost.

[0006] The technical scheme for solving the above technical problem of the utility model is as follows: a large flat plate rough grinding support, comprising:

[0007] A fixing hole is formed in the center of the support plate, and at least three positioning holes are arranged at the edge of the support plate;

[0008] A support column is arranged in each positioning hole and connected with the positioning hole through threads.

[0009] The utility model uses a support plate as a fixed angle grinder or pneumatic polisher and the like, and then uses at least three support columns to adjust the level and height of the support plate, so that the angle grinder or other polishing tool is prevented from excessive grinding.

[0010] Further, a level bubble is arranged on the support plate.

[0011] The advantage of this step is that it uses a bubble level to indicate whether the surface is level, eliminating the need for additional tools such as a spirit level.

[0012] Furthermore, at least three of the aforementioned positioning holes are evenly distributed in a ring on the support plate.

[0013] The beneficial effect of this step is based on the principle of determining a plane by three points.

[0014] Furthermore, the thread is a fine-pitch thread.

[0015] The benefits of this step are: finer threads have a smaller pitch and higher adjustment accuracy.

[0016] Furthermore, a ranging rod is provided on the adjacent side of each of the positioning holes.

[0017] The benefits of this step include: measuring the distance between the support plate and the flat workpiece using a distance measuring rod to determine the grinding amount.

[0018] Furthermore, a protective ring is provided at the lower edge of the fixing hole.

[0019] The beneficial effects of this step are: the protective ring serves a protective function, preventing the rotating grinding head or polishing disc from falling off and flying out, causing injury.

[0020] The beneficial effects of this utility model are:

[0021] The support frame can keep relatively parallel to the workpiece surface and the distance between them can be adjusted. The grinding amount of the grinding tool on it is determined by the support frame, so as to avoid excessive grinding during manual grinding, which would cause the workpiece to be scrapped.

[0035] Embodiments

[0036] As Figures 1-2 shown, the utility model provides a big panel rough grinding support, including:

[0037] Supporting plate 1, the centre of supporting plate 1 is equipped with fixed hole 11, and the edge of supporting plate 1 is equipped with at least three positioning holes 12;

[0038] Each positioning hole 12 is equipped with support column 2, and support column 2 is connected with positioning hole 12 through screw thread, and the end of support column 2 is conical pointed head, and the contact area with workpiece is small, and error is reduced.

[0039] The utility model utilizes supporting plate 1 as fixed angle grinder or pneumatic polisher and other tools, then utilizes at least three support columns 2 to adjust the level and height of supporting plate 1, avoids that angle grinder or other polishing tools are excessively ground.

[0040] On the basis of the above technical scheme, the supporting plate 1 is equipped with a level bubble 3.

[0041] Whether the supporting plate 1 is level is shown by the level bubble 3, the supporting plate can be observed during grinding, without using tools such as a level, to avoid grinding deviation.

[0042] On the basis of the above technical scheme, the at least three positioning holes 12 are annularly and uniformly distributed on the supporting plate 1.

[0043] Based on the principle of three-point determination of a plane, the supporting plate 1 can be made more stable.

[0044] On the basis of the above technical scheme, the screw thread is a fine thread.

[0045] The pitch of the fine thread is smaller, and the adjustment accuracy is higher.

[0046] On the basis of the above technical scheme, the adjacent side of each positioning hole 12 is equipped with a distance measuring rod 4, which is a micrometer without a frame and a small anvil, and the measurement accuracy reaches 0.01 mm.

[0047] The distance between the support plate 1 and the flat plate workpiece is measured by the distance measuring rod 4 to determine the grinding amount.

[0048] On the basis of the above technical scheme, the lower edge of the fixing hole 11 is provided with a protective ring 13.

[0049] The protective ring 13 plays a protective role to prevent the rotating grinding head or polishing piece from flying out and causing injury.

[0050] The specific application method of the present application is as shown in the drawings. Figure 3 Taking the angle grinder 5 as an example, the protective cover of the angle grinder 5 itself can be removed, and then the mounting hole of the protective cover is connected with the fixing hole 11. The size of the fixing hole 11 is matched with the angle grinder 5, and the bolt hole provided on the fixing hole 11 also needs to correspond to the position of the protective cover mounting hole of the angle grinder 5, and then the bolt is connected. Then the polishing piece 51 is installed. The polishing piece 51 can adopt a hard polishing wheel or a soft wool polishing wheel, which can be selected according to the polishing requirement.

[0051] Then the height of the convex point on the flat plate workpiece is detected to determine the grinding amount, and the grinding amount is d.

[0052] Then the end of the three distance measuring rods 4 is adjusted to be flush with the outer end surface of the polishing piece 51, and the current values A1, A2 and A3 of each are read. Then the multiple distance measuring rods 4 are retracted according to the values A1-d, A2-d and A3-d, and the tip of the support column 2 is adjusted to be flush with the end of the distance measuring rod 4. That is, the grinding amount setting is completed.

[0053] Opening the angle grinder 5 starts polishing for a period of time to complete rough grinding and achieve the purpose of removing the convex point.

[0054] It should be noted that the polishing piece 51 is installed on the rotating shaft of the angle grinder 5, and a spring needs to be sleeved on the rotating shaft. The spring is between the polishing piece 51 and the angle grinder 5, so that the polishing piece 51 has a retraction allowance. Otherwise, the polishing piece 51 will always exceed the tip of the support column 2 and cannot reach the flush state. In addition, it should be noted that the support column 2 is used for final positioning instead of directly using the distance measuring rod 4 for positioning, in order to avoid affecting the accuracy of the distance measuring rod 4 due to long-term stress.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical scheme of the present application, but not to limit it. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical scheme recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. The modification or replacement does not change the essence of the corresponding technical scheme out of the scope of the technical scheme of the embodiments of the present application.
