[0001] The invention relates to the technical field of mechanical workpiece positioning, in particular to a positioning device for guide column grinding processing. Background Art

[0002] The method of cutting the workpiece surface with a grinding wheel on a grinding machine is called grinding, which is one of the main methods of precision machining of parts. Grinding is mainly used for finishing of internal and external cylindrical surfaces, internal and external conical surfaces, planes and forming surfaces (such as splines, threads, gears, etc.) of parts to obtain higher dimensional accuracy and lower surface roughness. Guide columns usually need to be ground on the outer cylindrical surface.

[0003] According to the Chinese patent publication number CN214559761U, the patent provides a workpiece positioning device for grinding processing, including an operating table, a placement groove is opened in the middle of the operating table, through holes are opened symmetrically on both sides of the placement groove at equal distances, a push-clamping device is arranged inside the through hole, a grinding roller is arranged above the placement groove, and both sides of the grinding roller are connected to the operating table through a sliding device. The device has a simple structure and is easy to operate and use. During specific use, a light source CCD camera takes a picture to position the workpiece to be processed, and a laser rangefinder detects its position. The data after the picture is taken and the data after the distance detection will be transmitted to the controller, and then the controller starts the hydraulic cylinder to drive the push-clamping device to move, so as to adjust the placement position of the workpiece and increase the accuracy of the workpiece placement and positioning. After the workpiece position adjustment is completed, the controller will start the movement of the sliding device to realize the grinding of the workpiece surface.

[0004] However, when the guide column is clamped by the clamp on the grinding machine, only the two ends of the guide column are pressed against each other. At this time, the guide column is suspended and clamped in the air. When it comes into contact with the grinding wheel, their resistance and friction can easily cause the risk of misalignment or even falling off of the guide column. Therefore, a positioning device for guide column grinding is proposed to solve the above problems. Summary of the invention

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a positioning device for guide column grinding, which has the following beneficial effects:

[0020] 1. The positioning device for guide column grinding processing adopts a clamping part that can adapt to the force degree of the guide column under different parameters to effectively clamp. The anti-slip sheet and pressure sensor on the rotating shaft cooperate to determine the clamping effect according to the force parameters of the guide columns of different sizes and materials to avoid damage to the guide column due to insufficient clamping or excessive clamping. The anti-slip part limits the guide column in the clamping and prevents it from falling off. The metal disk is adsorbed with the magnetic disk, and the bending sheet on the support arm contacts the end of the guide column. The rotating screw can adjust the distance between the bending sheet and the guide column to adapt to different calibers. The guide column is limited during the grinding process to prevent the guide column from shaking, loosening or falling off due to the pressure of the grinding wheel and the centrifugal force of high-speed rotation.

[0021] 2. The positioning device for guide column grinding processing adopts the setting of the anti-cutting part to adapt to the change of the grinding position of the grinding wheel. The position of the grinding wheel is detected by an infrared distance sensor. When the grinding wheel approaches, the electric push rod pushes the sliding rod and the magnetic disk to move, driving the metal disk of the anti-slip part to approach the triangular plate, so that the bending piece is away from the end of the guide column to avoid the grinding wheel from knocking and wearing the fixture and other parts. During the sliding grinding process of the grinding wheel, a safe distance is always maintained from the parts, which not only prevents structural wear, but also exposes the end of the guide column for complete grinding when needed.

[0022] 3. The positioning device for the guide column grinding process adopts an adjustment part to locate the position of the guide column grinding process. The motor drives the stud to rotate, driving the triangle plate to move on the positioning rod, so as to achieve effective clamping and removal of guide columns of different sizes, ensuring that the guide column is in the grinding position. The recovery part reduces the pollution of debris. The material receiving cloth is connected to the cross bar through a slip ring, and the opening area can be changed as the distance of the triangle plate is adjusted, so as to effectively catch the debris scattered during the grinding process, reduce the pollution to the work surface and reduce the debris from entering between the parts.

[0023] 4. The positioning device for the guide column grinding process uses the inductive adjustment method to always ensure that the guide column is subjected to clamping force and limiting capacity during the grinding process, thereby improving the safety of grinding, effectively avoiding the risk of the guide column shaking and falling off due to the resistance of the grinding wheel and the centrifugal force, and ensuring the stability of the grinding process. The limit compensation of the bending piece and the adaptive adjustment of the anti-chip part make the guide column more stable during the grinding process, which helps to improve the grinding quality and accuracy.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-7 The present invention provides a technical solution: a positioning device for guide column grinding, comprising a sliding seat 1, a mounting seat 9 is attached to the bottom of the sliding seat 1, the mounting seat 9 is used to be installed and adapted on the existing technical grinding machine, a machine groove is provided on the top of the mounting seat 9, a linear motor 10 is installed on the inner wall of the machine groove, a mover end of the linear motor 10 is fixedly connected to the sliding seat 1, an anti-cutting part 2 is arranged on the top of the sliding seat 1, and is used to adapt to the grinding position change of the grinding wheel to prevent structural wear, a clamping part 3 is installed on the anti-cutting part 2, and is used to adapt to the force degree of the guide column under different parameters and effectively clamp, an anti-slip part 4 is adsorbed on the clamping part 3, and is used to limit and compensate the guide column in the clamping and prevent it from falling off, an adjusting part 6 is installed on the sliding seat 1, and is used to locate the position of the guide column for grinding, a driving part 7 is installed on one side of the sliding seat 1, and is used to drive the guide column to rotate at high speed and perform grinding operation with the grinding wheel, and a recovery part 8 is installed on the top of the sliding seat 1, and is used to receive the debris spilled during the grinding process.

[0034] In this embodiment, since the grinding wheel grinding not only requires high-speed friction between the guide column and the grinding wheel, but also requires the grinding wheel to slide on the outer surface of the guide column to completely cover the outer wall surface of the guide column, it is necessary to prevent the grinding wheel from sliding and wearing the fixture and other parts. The anti-cutting part 2 of this case includes a triangular plate 21, and an electric push rod 22 is installed on the side wall of the triangular plate 21. The inner rod end of the electric push rod 22 is fixedly connected with a sliding ring 23. The side wall of the sliding ring 23 is fixedly connected with two sliding rods 24. The two sliding rods 24 slide through the triangular plate 21. The through ends of the two sliding rods 24 are fixedly connected with a magnetic disk 25. A sensor 26 is installed at the top offset, and a signal connection is formed between the sensor 26 and the electric push rod 22. The sensor is an infrared distance sensor, and the reference model is Sharp GP2Y0A02YK0F. The infrared light is emitted, and when the light is irradiated on the object and reflected back, the sensor receives the reflected light and calculates the distance according to the propagation time or intensity change of the light, thereby generating an electrical signal. There are two anti-chipping parts 2, and the two anti-chipping parts 2 are symmetrically arranged on both sides of the top of the sliding seat 1, wherein a triangular plate 21 of one anti-chipping part 2 is fitted with the sliding seat 1, and a triangular plate 21 in the other anti-chipping part 2 is fixedly connected with the sliding seat 1.

[0035] In order to adapt to guide columns of different sizes and ensure the force degree of guide columns of different materials, so as to adjust the tightness of clamping, the clamping part 3 of this case includes a rotating shaft 31, which movably penetrates the triangular plate 21 and is rotatably connected to the triangular plate 21, and the magnetic disk 25 is movably sleeved on the end of the rotating shaft 31, and one end of the rotating shaft 31 is fixedly connected with an anti-skid sheet 32, which is made of hard rubber material, and an embedded hole is opened in the center of the anti-skid sheet 32, and a sensor 2 33 is installed at the end of the rotating shaft 31, and the sensor 2 33 is a pressure sensor, and its model can refer to the series of sensors of Shenzhen Ruisite Sensing Instrument Co., Ltd., and the sensor 2 33 is also arranged in the embedded hole, and there are two clamping parts 3, and the other clamping part 3 is installed on the triangular plate 21 of the other anti-cutting part 2, and the two clamping parts 3 are symmetrically arranged with each other, and each guide column has different parameters. After clamping according to the actual parameters, the controllable pressure value of the current guide column is reached by the resistance of the pressure sensor, thereby achieving a correct clamping effect and avoiding damage to the guide column caused by insufficient clamping or excessive tightening.

[0036] It is worth noting that in order to further prevent the guide column from being misaligned and falling off due to the pressure of the grinding wheel during grinding, the anti-slip portion 4 in this case includes a metal disk 41, which is slidably sleeved on the end of the rotating shaft 31. The metal disk 41 and the magnetic disk 25 are attracted to each other by opposite charges, and the metal disk 41 can be prompted to move with the magnetic disk 25 through magnetic adsorption. Support arms 42 are fixedly connected on both sides of the metal disk 41, and bending pieces 43 are provided on the sides where the two support arms 42 are close to each other. The two bending pieces 43 are symmetrically arranged, and the two support arms 42 are threaded with screws 44, and the two support arms 42 are slidably penetrated by limiting rods 45, each screw 44 is rotatably connected to the bending piece 43 on the same side, and each limiting rod 45 is fixedly connected to the bending piece 43 on the same side, and the screw 44 is rotated by the two support arms 42. To adjust the distance between the two bending pieces 43, so as to adapt to the caliber of the current guide column, there are two anti-slip parts 4 in this case, and the two anti-slip parts 4 ensure the limiting stability of the two ends of the guide column and the force balance during operation. The metal disk 41 in the other anti-slip part 4 is adsorbed on the magnetic disk 25 in the other anti-cutting part 2. The two anti-slip parts 4 are symmetrically arranged with each other, and the guide column 5 is clamped between the anti-slip sheets 32 in the two clamping parts 3. The two ends of the guide column 5 are respectively abutted against the sensors 33 in the two clamping parts 3, and the two ends of the guide column 5 are respectively contacted and connected with each bending piece 43. The contact connection is not tight, but ensures that the guide column 5 can fit and rotate between the bending pieces 43, so as to further perform limiting compensation on the clamped guide column 5 to prevent the end of the guide column 5 from being subjected to force dislocation, shaking and other problems.

[0037] In order to adapt to guide columns 5 of different sizes to be able to effectively clamp and disassemble, and to place the guide column 5 in the grinding processing position, the adjustment part 6 of this case includes a support 61, which is installed on one side of the sliding seat 1, and a motor 62 is installed on the support 61. A connecting plate 63 is installed on the top of the sliding seat 1, and a positioning rod 64 is fixedly connected between the connecting plates 63. There are two positioning rods 64. The two triangular plates 21 are slidably sleeved on the two positioning rods 64. A stud 65 is fixedly connected to the output shaft of the motor 62. The stud 65 threadedly penetrates one of the triangular plates 21 and continues to move through the other triangular plate 21. The penetration end of the stud 65 It is rotatably connected to one of the connecting plates 63. In order to enable the guide column 5 to rotate at high speed and perform grinding operations with the grinding wheel without affecting the normal operation of other components of this case, the driving part 7 of this case includes a support platform 2 71. The support platform 2 71 is installed on the other side of the sliding seat 1. A frame 72 is installed on the support platform 71. A motor 2 73 is installed on the frame 72. A connecting rod 74 is fixedly connected to the output shaft of the motor 2 73. The connecting rod 74 is fixedly connected to the adjacent rotating shaft 31. The sliding ring 23 on the triangular plate 21 fixed on the sliding seat 1 is slidably sleeved on the outer wall of the connecting rod 74. The work of the anti-cutting part 2 will not cause any collision or obstruction with the driving part 7.

[0038] It is worth mentioning that in order to reduce the pollution of debris on the work surface and further reduce the grinding debris from being scattered between various components, the recovery part 8 in this case includes two vertical rods 81, and the two vertical rods 81 are fixedly connected to the top of the sliding seat 1, and the tops of the two vertical rods 81 are fixedly connected to a cross rod 82, and the ends of the two cross rods 82 slide through the two triangular plates 21 respectively, and the two cross rods 82 are movably sleeved with slip rings 83, and the slip rings 83 are fixedly connected with a material receiving cloth 84. During the distance adjustment process between the triangular plates 21, the slip ring 83 will slide with the triangular plates 21, thereby adjusting the opening area of ​​the material receiving cloth 84, so as to ensure that the debris scattered downward can be effectively caught.

[0039] Working principle: the mounting seat 9 is threadedly mounted for assembly with the workbench of the grinder, so that the device is located between the grinding wheel and the workbench of the grinder. A guide column 5 is placed horizontally between the two rotating shafts 31. By controlling the operation of the motor 1 62, the stud 65 is rotated to drive one triangular plate 21 to approach the other triangular plate 21. The positioning rod 64 ensures the stability of the movement of the triangular plate 21, thereby avoiding the problems of shaking and misalignment. After the triangular plate 21 moves, the guide column 5 is clamped between the two rotating shafts 31, and the anti-skid sheet 32 ​​is used to improve the anti-skid ability. The anti-skid sheet 32 ​​is squeezed and deformed by force, thereby causing the sensor 2 33 to be pressure-sensitive, and then the threshold is determined according to the actual force parameters of the current guide column 5. When the pressure value of the sensor 2 33 reaches the threshold, the motor 1 62 is turned off through an electrical signal, thereby completing the clamping of the guide column 5.

[0040] The two ends of the clamped guide column 5 are respectively located between the corresponding bending pieces 43. The distance between the bending piece 43 and the end of the guide column 5 is adjusted by rotating the screw 44, so that the bending piece 43 contacts the guide column 5 for limiting. The bending piece 43 can be removed through the metal plate 41 during later maintenance and cleaning. The metal plate 41 and the magnetic plate 25 can be quickly installed and disassembled by adsorption, which is convenient for daily use and replacement. Under the limiting condition of the anti-detachment part 4, the friction resistance of the grinding wheel on the guide column 5 will be compensated by the limiting force of the bending piece 43, so there is no risk of the guide column 5 shaking and falling off from the end.

[0041] The connecting rod 74 is driven to rotate by the motor 2 73, and then the guide column 5 is driven to rotate at high speed in the clamping state through the rotating shaft 31. The grinding wheel approaches the guide column 5 through the mechanical arm of the grinder in the prior art, thereby producing a grinding effect. The linear motor 10 drives the sliding seat 1 to reciprocate through the reciprocating motion, thereby prompting the clamped guide column 5 to reciprocate, and realizes the effect of sliding grinding in the grinding process. Since the bending piece 43 covers the outer wall surfaces of both ends of the guide column 5 to a certain extent, that is, the two ends of the guide column 5 will have the problem of inadequate grinding. Therefore, when sliding grinding, when the grinding wheel approaches the sensor 1 26 on one side, the sensor 1 26 will detect the distance change caused by the grinding wheel blocking the infrared rays, thereby generating an electrical signal to control the electric push rod 22 to work. The inner rod of the electric push rod 22 pushes the sliding ring 23 and pulls the sliding rod 24 to slide, thereby prompting the magnetic disk 25 to drive the metal disk 41 to approach the triangular plate 21, and then the bending piece 43 moves away from the end of the guide column 5 that it contacts, and always keeps close to the approaching grinding wheel The guide post 5 is then moved back to its original position and the guide post 5 is moved back to its original position, which in turn causes the guide post 5 to move back to its original position, thereby preventing the guide post 5 from moving.

[0042] The motor involved in this case can be a YCT series speed-regulating motor produced by Shanghai Fengxin Transmission Machinery Co., Ltd. Its supporting circuits and power supplies are also provided by the manufacturer. It can be fully implemented by technical personnel in this field without further elaboration.
