Description

Technical Field

[0001] This utility model relates to the field of cutting tool testing technology, specifically a cutting tool sharpness testing platform with a clamping mechanism. Background Technology

[0002] In the fields of cutting tool production, quality inspection and scientific research, tool sharpness is a key indicator for measuring tool performance, which directly affects its cutting efficiency, service life and safety of use. As a professional testing equipment, the tool sharpness test bench needs to accurately clamp the tool and apply a standard load to simulate the actual cutting conditions in order to obtain reliable test data.

[0003] Most tool sharpness testing stands use a screw-driven clamping method to limit the movement of tools. The screw is rotated to move the limiting plate and clamp the tool. However, in this structure, the screw is prone to stripping due to frequent stress after long-term operation, causing the limiting plate to lose its fixed position. As a result, the tool may loosen or even fall off during the test, which not only causes the test data to be distorted, but may also cause safety accidents due to the tool falling off. In order to solve the above problems, the inventor proposes a tool sharpness testing stand with a clamping mechanism. Utility Model Content

[0004] To address the problem that the screw is prone to stripping due to frequent stress when pushing the limiting plate to position the tool, thus preventing the limiting plate from maintaining a fixed position, the purpose of this utility model is to provide a tool sharpness testing platform with a clamping mechanism.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a tool sharpness testing platform with a clamping mechanism, comprising a base, a support shaft symmetrically fixedly connected to the top of the base near the center of one side, a support plate slidably connected between the outer rings of the two support shafts, a connecting block fixedly connected to the bottom of the support plate near the center of one side, an installation block provided on the side of the connecting block near the bottom center, a positioning plate symmetrically fixedly connected to the bottom of the installation block near the center, a limiting plate fixedly connected to the bottom of the positioning plate near one side, a block fixedly connected to the bottom of the positioning plate near the other side, a screw rotatably connected to the block internally by a thread, a rotating disk fixedly connected to the side of the screw, a plurality of limiting holes arranged in a ring near the screw on the block, a sleeve shaft fixedly connected to the side of the rotating disk near the outer ring, a sliding shaft slidably inserted into the side of the sleeve shaft and adapted to the limiting holes, a spring fixedly connected to the side of the sliding shaft, and the other end of the spring fixedly connected to the inner wall of the sleeve shaft.

[0006] Preferably, a second limiting plate is slidably connected to the bottom end of the positioning plate near the limiting plate, and the screw side end is threadedly rotatably connected to the second limiting plate. A sharpness tester body is provided at the top of the base near the center of the other side, and the sharpness tester body and the positioning plate are on the same horizontal plane.

[0007] Preferably, a limiting disk is symmetrically fixedly connected to the outer ring of one of the support shafts near both sides, and a top plate is fixedly connected between the top ends of the two support shafts.

[0008] Preferably, a lead screw is rotatably connected at the center of the bottom end of the top plate, and the support plate is rotatably connected to the lead screw via a thread.

[0009] Preferably, a motor is provided at the center of the top of the top plate, the output end of the motor passes through the top plate and is fixedly connected to the lead screw, and an emergency button is provided at the top of the base and near one side corner.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. In this utility model, the cutting tool is placed between two sets of limiting plates, and then the screw drives the second limiting plate to move towards the first limiting plate to achieve clamping. In conjunction with the use of springs, sliding shafts and limiting holes, the limiting effect on the rotating disk is achieved, which avoids the limiting plate from moving and the cutting tool from falling off due to the screw stripping, thus improving the safety of the device.

[0012] 2. In this utility model, the starting motor drives the lead screw to rotate, causing the support plate to descend under the action of the support shaft, which in turn drives the tool to descend. In conjunction with the sharpness tester body, the sharpness test of the tool can be completed. The whole testing process is simple and easy to implement, and the test results can be obtained quickly. Attached Figure Description

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.

[0020] Example: Figure 1-4 As shown, this utility model provides a technical solution: a tool sharpness testing platform with a clamping mechanism, including a base 1, with support shafts 2 symmetrically fixedly connected to the top of the base 1 and near the center of one side, and a support plate 4 slidably connected between the outer rings of the two support shafts 2, and the support plate 4 slidably connected between the outer rings of the two support shafts 2 through bearings, which can reduce sliding friction and make the support plate 4 move more smoothly, a connecting block 41 fixedly connected to the bottom of the support plate 4 and near the center of one side, and a mounting block 42 provided on the side end of the connecting block 41 near the bottom center, a positioning plate 43 symmetrically fixedly connected to the bottom end of the mounting block 42 and near the center, a limit plate 44 fixedly connected to the bottom end of the positioning plate 43 and near one side, and a block 46 fixedly connected to the bottom end of the positioning plate 43 and near the other side, with a screw 47 rotatably connected to the inside of the block 46, and markings machined inside the block 46. A threaded hole is provided to mate with the screw 47, facilitating the rotation of the screw 47. A rotating disk 5 is fixedly connected to the side end of the screw 47. Several ring-shaped limiting holes 51 are provided on the block 46 near the screw 47. The surface of the rotating disk 5 is provided with anti-slip texture to facilitate the operator to apply force to rotate it. A sleeve shaft 52 is fixedly connected to the side end of the rotating disk 5 near the outer ring. A sliding shaft 53 is slidably inserted into the side end of the sleeve shaft 52, and the sliding shaft 53 is adapted to the limiting holes 51. A spring 54 is fixedly connected to the side end of the sliding shaft 53, and the other end of the spring 54 is fixedly connected to the inner wall of the sleeve shaft 52. The sliding shaft 53 can be inserted into the limiting hole 51 to achieve the limiting effect. The electrical components in this application are electrically connected to their compatible power supply through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The detailed connection methods are known in the art.

[0021] The bottom end of the positioning plate 43 and near the first limiting plate 44 are slidably connected to the second limiting plate 45, and the side end of the screw 47 is threadedly connected to the second limiting plate 45.

[0022] By adopting the above technical solution, a guide groove is provided at the bottom of the positioning plate 43 to facilitate the smooth sliding of the second limiting plate 45. The distance between the second limiting plate 45 and the first limiting plate 44 can be adjusted by rotating the screw 47 to accommodate the clamping of tools of different sizes.

[0023] A sharpness tester body 3 is provided at the top of the base 1 and near the center of the other side, and the sharpness tester body 3 and the positioning plate 43 are on the same horizontal plane.

[0024] By adopting the above technical solution, several mounting holes are opened at the top of the base 1 near the center of the other side, which facilitates the installation of the sharpness tester body 3 to complete the tool testing.

[0025] One of the support shafts 2 is symmetrically fixedly connected to a limit plate 1 on its outer ring and near both sides.

[0026] By adopting the above technical solution, the diameter of the limiting disk is larger than the outer diameter of the support shaft 2, which is used to limit the vertical movement range of the support plate 4 and prevent it from detaching from the support shaft 2.

[0027] A top plate 21 is fixedly connected between the top ends of the two support shafts 2.

[0028] By adopting the above technical solution, the top plate 21 can be made of aluminum alloy, which is lightweight and high-strength, and serves as a connection and support.

[0029] A lead screw 23 is rotatably connected at the center of the bottom end of the top plate 21, and the support plate 4 is rotatably connected to the lead screw 23 by a thread.

[0030] By adopting the above technical solution, after the lead screw 23 rotates, the support plate 4 connected by the threaded rotation can be raised and lowered.

[0031] A motor 22 is installed at the center of the top of the top plate 21, and the output end of the motor 22 passes through the top plate 21 and is fixedly connected to the lead screw 23.

[0032] By adopting the above technical solution, the working motor 22 is started, thereby causing the fixedly connected lead screw 23 to rotate.

[0033] An emergency button 11 is located at the top of the base 1 and near one corner.

[0034] By adopting the above technical solution, in case of an emergency, pressing the emergency button 11 can immediately cut off the power supply to the equipment, stop all operating components, and ensure the safety of the operators.

[0035] Working principle: When using this device, first place the tool to be tested between two sets of limiting plates 44 and 45 (rubber pads can be set at the opposite ends of limiting plates 44 and 45 to prevent the tool from slipping). Then, pull the sliding shaft 53 simultaneously to compress the spring 54. Then, rotate the two screws 47 simultaneously, which will move the limiting plate 45 towards the limiting plate 44, thus achieving the clamping and limiting effect on the tool. Finally, release the force on the sliding shaft 53. Under the action of the spring 54, the sliding shaft 53 can be inserted into the limiting hole 51 to achieve the limiting effect on the rotating disk 5. This avoids the situation where the limiting plate 45 moves due to the failure of the screws 47 after long-term operation (and the tool will fall off), thereby improving the safety of the overall device during use.

[0036] After the tool is positioned, the working motor 22 is started, which causes the fixedly connected lead screw 23 to rotate. This causes the threaded rotating support plate 4 to descend under the action of the two support shafts 2, thereby driving the tool to descend and complete the sharpness test (it needs to be used with the existing mature sharpness tester body 3, which is a device that can be purchased on the market by those skilled in the art. The device has not been structurally modified in this article. Therefore, those skilled in the art are familiar with its working principle based on their professional knowledge and can use it skillfully. Therefore, this article will not elaborate on it further). This makes testing the sharpness of the tool relatively simple and quick.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
