DETAILED DESCRIPTION

[0023] The utility model will be further explained in connection with the drawings and specific embodiments, but the protection scope of the utility model is not limited to this.

[0024] Example one:

[0025] As Figures 1 to 4 shown, an input shaft clamping tool, including bottom plate 7, bottom plate 7 is connected with support tool 6, support tool 6 is connected with clamping plate tool 5, one side of clamping plate tool 5 is equipped with telescopic device 1, the other side of clamping plate tool 5 is equipped with clamping shaft hole 16.

[0026] The main architecture of the input shaft clamping tool includes a bottom plate 7, and a plurality of positioning holes and mounting holes are designed on the bottom plate 7. These hole positions are precisely measured and processed to ensure the cooperation accuracy between the machine tool workbench and the support tool 6. The positioning holes are used to ensure the positional accuracy of the tool during installation. The surface of the bottom plate 7 will be precisely ground or polished to achieve the required surface roughness and flatness, ensuring that the close cooperation between the support tool 6 will not be affected by the unevenness of the cooperation position, resulting in poor fixing effect during installation and affecting the axial positioning of the input shaft.

[0027] Because the input shaft clamping tool of the utility model is installed in the machine tool as a clamp, its volume needs to be smaller, and the area occupied in the machine tool is also smaller. The bottom plate 7 and the support tool 6 are fixedly connected by fixing bolts 2, but the fixing bolts 2 are not connected to the machine tool. The bottom plate 7 is rotatably connected to the machine tool, and the clamping tool is rotatably connected to the machine tool through a rotating shaft. The clamping tool can rotate a certain angle on the machine tool.

[0028] The support tool 6 is connected with the clamping plate tool 5. The support tool 6 is in the shape of a spoon, and the contact area of the support tool 6 with the bottom plate 7 is the largest, which increases the contact area with the bottom plate 7, making the installation of the support tool 6 and the bottom plate 7 more stable and less likely to shake. After the support tool 6 extends a bottom plate fixed section 10 in the horizontal direction, it vertically extends a clamping plate connecting section 11 to cooperate with the clamping plate tool 5.

[0029] The structural design of the support tool 6 is a one-piece spoon-shaped structure, which enhances the torsion resistance and bending resistance of the support tool 6, and also ensures the stability of the support tool 6 when bearing. At the same time, the support tool 6 and the bottom plate 7 are convenient and fast to disassemble and assemble.

[0030] The support tool 6 is divided into two regions according to functional requirements, including a bottom plate fixing section 10 and a clamping plate connecting section 11. The surface roughness of the contact surface between the bottom plate fixing section 10 and the bottom plate 7 is small, and the precision is high. The cooperation and installation between the bottom plate fixing section 10 and the bottom plate 7 are tight, and it is not easy to produce fluctuations or shaking, and it is stably connected with the bottom plate 7. It ensures the accuracy and speed of the input shaft fixing center. The clamping plate connecting section 11 is a vertical columnar structure, the top end of which is embedded in the clamping plate tool 5 and clamped in the inside of the clamping plate tool 5, and the clamping plate tool 5 is fixed and supported. The surface precision requirement of the contact surface between the clamping plate connecting section 11 and the clamping plate tool 5 is also high, which ensures that the clamping plate tool 5 can remain horizontal after the clamping plate connecting section 11 is fixed and connected with the clamping plate tool 5, and does not deviate.

[0031] The clamping plate tool 5 takes the clamping shaft hole 16 as the center, and the contraction section 20 and the fixed section 21 are respectively extended on both sides to form a clamping mechanism. The contraction section 20 is connected with the output end of the telescopic device 1, and the diameter of the clamping shaft hole 16 is controlled through the driving of the telescopic device 1. Thus, the accurate clamping and releasing operation of the input shaft is realized. The fixed section 21 is fixedly connected with the main body part of the telescopic device 1, which provides stable support for the whole clamping plate tool 5.

[0032] In order to quickly and conveniently clamp and fix the input shaft, the clamping plate tool 5 extends the contraction section 20 and the fixed section 21 to both sides of the clamping shaft hole 16 around the clamping shaft hole 16. The main part of the contraction section 20 and the fixed section 21 remains parallel when the clamping plate tool 5 is in the initial state.

[0033] The end of the contraction section 20 is fixedly connected with the output end of the telescopic device 1, and the angle of rotation of the contraction section 20 can be controlled through the telescoping of the output end of the telescopic device 1, thereby controlling the distance between the contraction section 20 and the fixed section 21 and reducing the diameter of the clamping shaft hole 16 to fix the input shaft. The fixed section 21 is fixedly connected with the main body part of the telescopic device 1 through the driving fixed part 12, which avoids the telescopic device 1 pulling the whole clamping tool to rotate. The clamping plate tool 5 and the telescopic device 1 indirectly constitute a whole through the driving fixed part 12, and are fixedly installed on the support tool 6.

[0034] The upper end horizontal surface of the bottom plate fixed section 10 of the support tool 6 is provided with an input shaft sleeve 4, which is matched with the diameter of the input shaft. One input shaft of one diameter is provided with one input shaft sleeve 4. The bottom of the input shaft sleeve 4 is a flange-like structure, which can be fixedly connected with the bottom plate fixed section 10. The input shaft sleeve 4 and the bottom plate fixed section 10 are convenient to disassemble and assemble. However, it should be noted that the input shaft sleeve 4 and the bottom plate fixed section 10 cannot be disassembled and assembled frequently, otherwise the matching precision between the input shaft sleeve 4 and the bottom plate fixed section 10 will be affected, thereby affecting the centering effect of the input shaft.

[0035] The center position of the input shaft sleeve 4 is provided with a sleeve shaft hole 15 which can be matched with the input shaft. The axis position of the sleeve shaft hole 15 is close to or even coincides with the axis position of the clamping shaft hole 16. In order to ensure that the input shaft can be directly placed into the sleeve shaft hole 15 after being placed from the clamping shaft hole 16, the axis of the clamping shaft hole 16 and the axis of the sleeve shaft hole 15 need to be close to or coincide with each other. In this way, the input shaft can directly pass through the clamping shaft hole 16 and be inserted into the input shaft sleeve 4.

[0036] The upper end surface of the clamping plate tool 5 is also fixedly provided with a sensor positioning plate 14. The sensor positioning plate 14 adopts a cantilever structure design. The flat plate structure extending from the sensor positioning plate 14 is located above the telescopic device 1, thereby providing positioning for the installation of the telescopic device 1. The sensor positioning plate 14 is provided with a positioning plate mounting hole 17 in parallel. The sensor positioning plate 14 is fixed to the clamping plate tool 5 through the positioning plate mounting hole 17. The end of the upper surface of the cantilever of the sensor positioning plate 14 is provided with a first positioning point 18 and a second positioning point 19. The first positioning point 18 and the second positioning point 19 are both positioning points when the clamping tool is driven to rotate.

[0037] Rotary flanges 9 are installed on the opposite upper and lower surfaces of the driving fixed part 12 and the matching surface of the telescopic device 1. The rotary flanges 9 play a buffering role and are convenient for clamping the driving fixed part 12, thereby fixedly installing the driving fixed part 12 and the clamping plate tool 5.

[0038] The other end of the bottom plate 7 provided with the support tool 6 is provided with a mushroom-shaped handle 3. The terminal connector 8 is suspended outside the bottom plate 7 near the position of the mushroom-shaped handle 3 and the support tool 6.

[0039] Embodiment two:

[0040] The structures of the embodiments are mostly close to each other. In this embodiment, how the input shaft clamping tool clamps the input shaft and positions the input shaft will be described.

[0042] The main structure of the input shaft clamping tool includes a base plate 7, and a plurality of positioning holes and mounting holes are designed on the base plate 7. The hole positions are precisely measured and processed to ensure the cooperation accuracy between the machine tool workbench and the support tool 6. The positioning holes are used to ensure the positional accuracy of the tool during installation. The surface of the base plate 7 is precisely ground or polished to achieve the required surface roughness and flatness, so that the close cooperation between the base plate 7 and the support tool 6 will not be affected by the unevenness of the cooperation position, which will affect the axial positioning of the input shaft during installation.

[0043] Because the input shaft clamping tool of the utility model is installed in the machine tool as a clamp, its volume needs to be smaller, and the area occupied in the machine tool is also smaller. The base plate 7 and the support tool 6 are fixedly connected through the fixing bolt 2, but the fixing bolt 2 will not be connected to the machine tool. The base plate 7 is rotatably connected with the machine tool, and the clamping tool is rotatably connected with the machine tool through a rotating shaft, so that the clamping tool can rotate by a certain angle on the machine tool.

[0044] The support tool 6 is connected with the clamping plate tool 5. The support tool 6 is in the shape of a spoon, and the contact area between the support tool 6 and the base plate 7 is the largest, which increases the contact area between the support tool 6 and the base plate 7, so that the installation of the support tool 6 and the base plate 7 is more stable and is not easy to shake. After the support tool 6 extends a base plate fixing section 10 in the horizontal direction, it vertically extends a clamping plate connecting section 11 to cooperate with the clamping plate tool 5.

[0045] The support tool 6 is designed in an integrated spoon-shaped structure, which enhances the torsional and bending resistance of the support tool 6 and also ensures its stability during loading. At the same time, the support tool 6 and the base plate 7 are easy and fast to disassemble and assemble.

[0046] The support tool 6 is divided into two areas according to the functional requirements, including the bottom plate fixed section 10 and the clamping plate connecting section 11. The surface roughness of the contact surface between the bottom plate fixed section 10 and the bottom plate 7 is small, and the precision is high. The installation is closely matched with the bottom plate 7, and it is not easy to produce fluctuations or shaking, and it is stably connected with the bottom plate 7. Ensure the accuracy and speed of the input shaft fixing pair. The clamping plate connecting section 11 is a vertical column structure, the top end of which is embedded in the clamping plate tool 5 and clamped in the inside of the clamping plate tool 5, and the clamping plate tool 5 is fixed and supported. The surface precision requirement of the contact surface between the clamping plate connecting section 11 and the clamping plate tool 5 is also high, which ensures that the clamping plate tool 5 can remain horizontal after the clamping plate connecting section 11 is fixed and connected with the clamping plate tool 5, and does not deviate.

[0047] The clamping plate tool 5 is centered on the clamping shaft hole 16, and the contraction section 20 and the fixed section 21 are respectively extended on both sides to form a clamping mechanism. The contraction section 20 is connected with the output end of the telescopic device 1, and the diameter of the clamping shaft hole 16 is controlled through the driving of the telescopic device 1. Thus, the accurate clamping and releasing operation of the input shaft is realized. The fixed section 21 is fixedly connected with the main body part of the telescopic device 1, and provides stable support for the entire clamping plate tool 5.

[0048] In order to quickly and conveniently clamp and fix the input shaft, the clamping plate tool 5 extends the contraction section 20 and the fixed section 21 to both sides of the clamping shaft hole 16 around the clamping shaft hole 16. The main part of the contraction section 20 and the fixed section 21 remains parallel when the clamping plate tool 5 is in the initial state.

[0049] The end of the contraction section 20 is fixedly connected with the output end of the telescopic device 1, and through the telescoping of the output end of the telescopic device 1, the angle of rotation of the contraction section 20 can be controlled, and thus the distance between the contraction section 20 and the fixed section 21 is controlled, and the diameter of the clamping shaft hole 16 is reduced. To fix the input shaft. The fixed section 21 is fixedly connected with the main body part of the telescopic device 1 through the driving fixed part 12, so as to avoid the telescopic device 1 pulling the clamping tool to rotate as a whole. The clamping plate tool 5 and the telescopic device 1 indirectly constitute a whole through the driving fixed part 12, and are fixedly installed on the support tool 6.

[0050] The input shaft sleeve 4 is arranged on the upper end horizontal surface of the bottom plate fixed section 10 of the support tool 6, and is matched with the diameter of the input shaft. One input shaft with a certain diameter is matched with one input shaft sleeve 4. The bottom of the input shaft sleeve 4 is a flange-like structure, which can be fixedly connected with the bottom plate fixed section 10. The input shaft sleeve 4 and the bottom plate fixed section 10 are convenient to disassemble and assemble. However, it should be noted that the input shaft sleeve 4 and the bottom plate fixed section 10 cannot be frequently disassembled and assembled, otherwise the matching precision between the input shaft sleeve 4 and the bottom plate fixed section 10 will be affected, thereby affecting the centering effect of the input shaft.

[0051] A sleeve shaft hole 15 matched with the input shaft is arranged at the center position of the input shaft sleeve 4. The axis position of the sleeve shaft hole 15 is close to or even coincides with the axis position of the clamping shaft hole 16. In order to ensure that the input shaft can be directly placed into the sleeve shaft hole 15 after being placed out of the clamping shaft hole 16, the axis of the clamping shaft hole 16 and the axis of the sleeve shaft hole 15 need to be close to or coincide with each other. In this way, the input shaft can directly pass through the clamping shaft hole 16 and be inserted into the input shaft sleeve 4. The sleeve shaft hole 15 is located below the clamping shaft hole 16.

[0052] A sensor positioning plate 14 is also fixedly installed on the upper end surface of the clamping plate tool 5. The sensor positioning plate 14 is designed in a cantilever structure. The flat plate structure extending from the sensor positioning plate 14 is located above the telescopic device 1, thereby providing positioning for the installation of the telescopic device 1. Parallel positioning plate mounting holes 17 are arranged on the sensor positioning plate 14. The positioning plate mounting holes 17 are step-shaped through holes. The sensor positioning plate 14 is fixed on the clamping plate tool 5 through the positioning plate mounting holes 17. A first positioning point 18 and a second positioning point 19 are arranged at the end of the upper surface of the cantilever of the sensor positioning plate 14. The first positioning point 18 and the second positioning point 19 are both positioning points when the clamping tool is driven to rotate.

[0053] Rotary flanges 9 are installed on the opposite upper and lower surfaces of the driving fixed part 12 and the matching surface of the telescopic device 1. The rotary flanges 9 play a buffering role and are convenient for clamping the driving fixed part 12, thereby fixedly installing the driving fixed part 12 and the clamping plate tool 5.

[0054] The other end of the bottom plate 7 on which the support tool 6 is installed is provided with a mushroom-shaped handle 3. A terminal connector 8 is suspended outside the bottom plate 7 near the position of the mushroom-shaped handle 3 and the support tool 6. The mushroom-shaped handle 3 is convenient for holding and installing the clamping tool. The terminal connector 8 is convenient for connecting the telescopic device 1 and the sensor and other components with the controller, transmitting signals, etc.

[0055] The utility model discloses a fixing and centering process of input shaft as follows, after input shaft is inserted into the sleeve shaft hole 15 of input shaft sleeve 4 after passing through the clamping shaft hole 16. The input shaft is fixed on the shaft section above the clamping shaft hole 16 by using the clamp, at this time, the telescopic device 1 is started, and the contraction section 20 is continuously close to the fixed section 21, when the pressure sensor in the clamping shaft hole 16 reads the pressure suddenly increases, it is explained that at least one section of input shaft is in rigid contact with the clamping shaft hole 16. At this time, the telescopic device 1 continues to exert the tightening force. And below the axis of the sleeve shaft hole 15 of input shaft sleeve 4, the rotary mechanism is installed at the position of the bottom of bottom plate 7 and machine tool connection, can drive the clamping tool to rotate around the axis of sleeve shaft hole 15, before rotating, the sensor contact is first contacted with No. 1 positioning point 18, confirms the position of clamping tool at this time.

[0056] When the clamping tool rotates, the input shaft remains unmoved, because the clamping shaft hole 16 after being compressed is no longer circular, but is oval-shaped, therefore, after the current position is clamped, the input shaft is not necessarily centered, and the clamping tool needs to rotate relative to the input shaft. When the clamping tool rotates relative to the input shaft, the telescopic device 1 can make the contraction section 20 closer to the fixed section 21, and the fixing is more reliable, and the centering is more accurate. No. 2 positioning point 19 is used for positioning the maximum rotating angle of the clamping tool.

[0057] Finally, it should be pointed out that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement to part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the utility model embodiments.
