Description

Technical Field

[0001] This utility model belongs to the field of cutting tool processing technology, specifically relating to a tool head bottom surface grinding machine. Background Technology

[0002] Machine tools are machines used to manufacture machinery. Lathes are machine tools that primarily use various cutting tools to machine rotating workpieces; therefore, the extent to which the cutting tools are used is a key factor in the quality of workpiece machining.

[0003] In the process of machining cutting tools, the bottom surface of the cutting tool needs to be ground. Grinding is required for grinding. However, existing grinding machines use a side-fixing method for clamping and fixing the cutting tool, but lack fixation in the direction perpendicular to the side-fixing. This can easily cause the cutting tool to deviate or become misaligned during grinding, affecting the accuracy of the grinding operation. To address this, we propose a cutting tool bottom surface grinding machine. Utility Model Content

[0004] The purpose of this utility model is to provide a tool head bottom surface grinding machine to solve the problem mentioned in the background art that the existing grinding machines used to clamp and fix the tool in a side-fixed manner, but lack fixation in the direction perpendicular to the side-fixed direction. This easily leads to the phenomenon of tool deviation and misalignment during grinding, affecting the accuracy of grinding operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottom surface grinding machine for a cutting head, comprising a support base, a fixed motor fixedly installed on the inner wall of the support base, a cross fixedly installed at the output shaft end of the fixed motor, hinge arms hinged at the four ends of the cross, a lower sliding plate hinged at the end of the hinge arm away from the cross, the lower sliding plate slidably extending through the support base and fixedly installed with an adjusting shell, an adjusting plate slidably disposed inside the adjusting shell, an upper sliding plate fixedly installed at the end of the adjusting plate, a top clamping plate fixedly installed at the end of the upper sliding plate, a bracket fixedly installed on the surface of the support base, a cylinder fixedly installed on the bracket, a grinding motor fixedly installed at the piston rod end of the cylinder, a grinding wheel fixedly installed at the output shaft end of the grinding motor, an mounting plate fixedly installed on the bracket, an exhaust fan, a dust extraction hood, and a collection box fixedly installed on the surface of the mounting plate, the air inlet and outlet of the exhaust fan being connected to the dust extraction hood and the collection box respectively, and the collection box having an opening on its side with a filter screen detachably installed at the opening.

[0006] The above solution utilizes a fixed motor, a cross, hinged arms, lower sliding plates, and upper sliding plates in conjunction with a clamping plate. The fixed motor drives the cross to rotate, and the hinged action of the four hinged arms drives the four lower sliding plates to move inward synchronously. This, in turn, through an adjusting shell and adjusting plate, drives the upper sliding plate to move the clamping plate. The four clamping plates move inward synchronously, achieving four-way clamping of the tool, improving the stability of the clamping effect, avoiding tool misalignment that easily occurs with bidirectional clamping, and ensuring the accuracy of grinding operations. The adjusting shell and adjusting plate allow the adjusting plate to slide up and down, adjusting the height of the clamping plate, making it suitable for clamping tools of different heights. The exhaust fan and dust hood, along with a collection box and filter, allow for centralized collection of grinding debris, preventing debris from scattering and affecting the working environment.

[0007] In the above scheme, it should be noted that the fixed motor, grinding motor and exhaust fan are all electrically connected to an external power supply.

[0008] In a preferred embodiment, a support ring is fixedly installed on the inner wall of the support base. An annular groove is formed on the lower surface of the support ring, and several arc-shaped sliders are slidably installed in the annular groove. The arc-shaped sliders are fixedly installed on the upper surface of the cross.

[0009] By using the above scheme, the support ring and the arc-shaped slider can be used to achieve rotational support for the cross, so that the cross moves smoothly under the action of the fixed motor and is not prone to shaking.

[0010] In a preferred embodiment, a sliding sleeve is slidably mounted on the outer surface of the upper sliding plate, and a plurality of guide rods are fixedly mounted on the lower surface of the sliding sleeve. The guide rods are slidably fitted with guide sleeves on their outer surfaces, and the guide sleeves are fixedly mounted on the outer surface of the bearing base.

[0011] By using the above solution, the sliding sleeve, in conjunction with the guide rod and guide plate, can provide a supporting effect and ensure better horizontal sliding stability of the upper sliding plate.

[0012] In a preferred embodiment, an adjusting rod is slidably inserted into the adjusting shell, a disc is fixedly mounted on one end of the adjusting rod, a plurality of adjusting holes are provided on the adjusting plate, and the other end of the adjusting rod is used in conjunction with the adjusting holes.

[0013] Using the above scheme, the adjusting rod and adjusting hole are used together. When the adjusting rod is disengaged from the adjusting hole, the adjusting plate is unlocked. At this time, the adjusting plate can slide up and down to adjust the position and height of the upper sliding plate and the top plate. After adjustment, the position is locked by inserting the adjusting rod into the adjusting hole.

[0014] In a preferred embodiment, a spring is sleeved on the outside of the adjusting rod, and the two ends of the spring are fixedly connected to the opposite surfaces of the adjusting shell and the disc, respectively.

[0015] By adopting the above solution, a spring is set up. When the adjusting rod is disengaged from the adjusting hole, the spring deforms. After the adjusting plate is adjusted to the correct position, the spring force drives the adjusting rod to reset and insert into the adjusting hole, thus achieving a convenient locking operation.

[0016] In a preferred embodiment, an assembly plate is fixedly installed at each of the four corners of the filter screen, and an assembly bolt is threaded onto the assembly plate. The side of the collection box has an assembly thread groove for the assembly bolt to be screwed into.

[0017] By using the above solution, the assembly plate and assembly bolts can be used together to achieve quick assembly and disassembly of the filter screen. The threaded connection has good stability and is not easy to loosen or fall off.

[0018] In a preferred embodiment, anti-slip teeth are attached to the side of the top plate, and the four anti-slip teeth are arranged opposite each other.

[0019] By using the above solution in conjunction with anti-slip toothed plates, the clamping effect on the cutting tool can be improved, and slippage can be avoided.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This tool head bottom surface grinding machine is equipped with a fixed motor, a cross, hinged arms, lower sliding plates, and upper sliding plates, which work together with a clamping plate. The fixed motor drives the cross to rotate, and the hinged action of the four hinged arms drives the four lower sliding plates to move inward synchronously. Then, the upper sliding plate drives the clamping plate to move through the adjusting shell and adjusting plate. The four clamping plates move inward synchronously, realizing four-way fixed clamping of the tool, improving the stability of the fixing effect, avoiding the tool deviation and misalignment that is easy to occur when fixing in two directions on the opposite side, and ensuring the accuracy of grinding operations.

[0022] This tool head bottom surface grinding machine is equipped with an adjustment shell and an adjustment plate. The adjustment plate can slide up and down to adjust the height of the top plate, which can be used to fix and clamp tools of different specifications and heights. With the help of the exhaust fan and dust hood, along with the collection box and filter screen, the debris generated during the grinding process can be collected and treated in a centralized manner to prevent debris from scattering and affecting the working environment.

Detailed Implementation

[0030] Please see Figure 1-6 This utility model provides a tool head bottom surface grinding machine, including a support base 1. A fixed motor 2 is fixedly installed on the inner wall of the support base 1. A cross 3 is fixedly installed at the end of the output shaft of the fixed motor 2. Each of the four ends of the cross 3 is hinged with a hinge arm 4. A lower sliding plate 5 is hinged to the end of the hinge arm 4 away from the cross 3. The lower sliding plate 5 slides through and extends out of the support base 1 and is fixedly installed with an adjusting shell 6. An adjusting plate 7 is slidably arranged inside the adjusting shell 6. An upper sliding plate 8 is fixedly installed at the end of the adjusting plate 7. A top sliding plate is fixedly installed at the end of the upper sliding plate 8. A bracket 10 is fixedly installed on the surface of the bearing base 1 and the plate 9. A cylinder 11 is fixedly installed on the bracket 10. A grinding motor 12 is fixedly installed on the piston rod end of the cylinder 11. A grinding wheel 13 is fixedly installed on the output shaft end of the grinding motor 12. An mounting plate 14 is fixedly installed on the bracket 10. An exhaust fan 15, a dust extraction hood 16, and a collection box 17 are fixedly installed on the surface of the mounting plate 14. The air inlet and outlet of the exhaust fan 15 are connected to the dust extraction hood 16 and the collection box 17, respectively. The collection box 17 has an opening on its side and a filter screen 18 is detachably installed at the opening.

[0031] By using a fixed motor 2, a cross 3, a hinged arm 4, a lower sliding plate 5, and an upper sliding plate 8 in conjunction with a clamping plate 9, the fixed motor 2 drives the cross 3 to rotate. The hinged action of the four hinged arms 4 drives the four lower sliding plates 5 to move inward synchronously. In turn, the adjusting shell 6 and the adjusting plate 7 drive the upper sliding plate 8 to move the clamping plate 9. The four clamping plates 9 move inward synchronously, achieving four-way clamping of the tool, improving the stability of the clamping effect, avoiding the tool deviation and misalignment that is easy to occur when clamping on both sides, and ensuring the accuracy of grinding operations. By using the adjusting shell 6 and the adjusting plate 7 in conjunction, the adjusting plate 7 can slide up and down to adjust the height of the clamping plate 9, which can be used to clamp tools of different specifications and heights. By using the exhaust fan 15 and the dust hood 16 in conjunction with the collection box 17 and the filter screen 18, the debris generated during the grinding process can be collected and treated in a centralized manner to prevent debris from scattering and affecting the working environment.

[0032] A support ring 19 is fixedly installed on the inner wall of the support base 1. An annular groove is opened on the lower surface of the support ring 19, and several arc-shaped sliders 20 are slidably installed in the annular groove. The arc-shaped sliders 20 are fixedly installed on the upper surface of the cross 3. By using the support ring 19 in conjunction with the arc-shaped sliders 20, the rotational support of the cross 3 can be realized, so that the cross 3 moves smoothly under the action of the fixed motor 2 and is not prone to shaking.

[0033] A sliding sleeve 21 is slidably installed on the outer surface of the upper sliding plate 8. Several guide rods 22 are fixedly installed on the lower surface of the sliding sleeve 21. The outer surface of the guide rods 22 is provided with a guide sleeve 23 on the sliding sleeve 21. The guide sleeve 23 is fixedly installed on the outer surface of the bearing base 1. By using the sliding sleeve 21 in conjunction with the guide rods 22 and the guide plate, a support effect can be achieved, ensuring better horizontal sliding stability of the upper sliding plate 8.

[0034] An adjusting rod 24 is slidably inserted into the adjusting shell 6. A disc 25 is fixedly installed at one end of the adjusting rod 24. Several adjusting holes are opened on the adjusting plate 7. The other end of the adjusting rod 24 is used in conjunction with the adjusting holes. When the adjusting rod 24 is disengaged from the adjusting hole, the adjusting plate 7 is unlocked. At this time, the adjusting plate 7 can slide up and down to adjust the position and height of the upper sliding plate 8 and the top plate 9. After adjustment, the position is locked by inserting the adjusting rod 24 into the adjusting hole.

[0035] A spring 26 is sleeved on the outside of the adjusting rod 24. The two ends of the spring 26 are fixedly connected to the opposite surfaces of the adjusting shell 6 and the disc 25, respectively. By setting the spring 26, the spring 26 deforms when the adjusting rod 24 is disengaged from the adjusting hole. After the adjusting plate 7 is adjusted to the correct position, the elastic force of the spring 26 drives the adjusting rod 24 to reset and insert into the adjusting hole, thus realizing a convenient locking operation.

[0036] Assembly plates 27 are fixedly installed at the four corners of the filter screen 18. Assembly bolts 28 are threaded on the assembly plates 27. The side of the collection box 17 has an assembly thread groove for the assembly bolts 28 to be screwed in. By using the assembly plates 27 and the assembly bolts 28 together, the filter screen 18 can be quickly disassembled and assembled. The threaded connection has good stability and is not easy to loosen or fall off.

[0037] Anti-slip teeth 29 are attached to the side of the clamping plate 9. The four anti-slip teeth 29 are arranged opposite each other. The anti-slip teeth 29 can be used in conjunction to improve the clamping effect on the tool and prevent slippage.

[0038] In use, place the grinding tool vertically on the surface of the support base 1. Adjust the position height of the clamping plate 9 according to the height specifications of the tool. During adjustment, pull the disc 25. The disc 25 drives the adjusting rod 24 to move away from the adjusting hole. At this time, the spring 26 deforms and the adjusting plate 7 is unlocked. Hold the adjusting plate 7 and move it up and down. The up and down movement of the adjusting plate 7 will drive the clamping plate 9 to move up and down through the upper sliding plate 8. After adjusting to the appropriate height, release the disc 25. Use the elasticity of the spring 26 to drive the adjusting rod 24 to reset and insert into the adjusting groove, thereby locking the position of the adjusting plate 7 and the clamping plate 9. Then, adjust the position of the clamping plate 9 at the other positions in sequence. After adjustment, start the fixed motor 2. The fixed motor 2 drives the cross 3 to rotate. The rotation of the cross 3 drives the hinge arm 4 to move. The lower sliding plate 5 moves inward, which in turn drives the upper sliding plate 8 to move the top clamping plate 9 inward through the adjusting shell 6 and the adjusting plate 7. The four top clamping plates 9 move inward synchronously and fit against the surface of the tool to achieve tool fixation and clamping. Then, the fixing motor 2 is stopped, and the cylinder 11 is started to drive the grinding motor 12 to move downward. The grinding motor 12 drives the grinding wheel 13 to rotate to achieve grinding. At the same time, the exhaust fan 15 is started during the grinding process. The grinding debris mixed in the air is extracted and transported to the collection box 17 through the dust extraction hood 16. After being filtered by the filter screen 18, it is discharged. After the operation is completed, the fixing motor 2 is controlled to reverse to release the tool lock. The cylinder 11 is controlled to drive the grinding motor 12 to move upward to reset. The exhaust fan 15 is stopped. The assembly bolt 28 is unscrewed to unlock the filter screen 18 and the filter screen 18 can be removed.
