Technical Problem

[0004]但是现有技术的模具导柱同轴度校准器的V型槽虽能通过斜面实现导柱的初步对中,但无夹持时,导柱仅靠重力与V型槽内壁接触,无额外约束力固定位置,转动导柱的过程中,一旦用力不均,导柱会在V型槽内发生横向偏移或纵向窜动,从而导致导柱易位移,从而导致降低了检测精度,同时现有技术的模具导柱同轴度校准器所有关键部件均为刚性直接接触与无缓冲约束,振动传递路径完全无阻断,当车间存在振动源(如隔壁冲床运行、空压机排气、叉车经过)时,即使振幅仅较低,磁性表座也会随振动轻微晃动,这种晃动会直接传递到百分表探头,导致指针出现无规律跳动(非导柱同轴度偏差导致),从而导致检测精度不稳定,合格导柱容易被误判为超差

Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically to a mold guide post coaxiality calibrator. Background Technology

[0002] Mold guide pillars are core guiding elements in the mold industry. They are typically cylindrical structures with shoulders and need to be used in conjunction with guide bushings. Their function is to ensure that the moving mold and fixed mold, as well as the upper mold and lower mold, can open and close with precise positioning, guiding the mold stroke. During the production and processing of mold guide pillars, a mold guide pillar coaxiality calibrator is required to test and calibrate the coaxiality of the mold guide pillars, thereby improving the accuracy of the mold and extending the service life of the equipment.

[0003] In existing technology, the coaxiality calibration of mold guide pillars involves placing two identical V-blocks parallel to each other on an inspection plate, with a spacing of half the total length of the guide pillar. The guide pillar is then horizontally placed into the V-groove of the V-block, ensuring that both ends extend beyond the V-block without skewing. A magnetic dial indicator holder is then attached to the inspection plate, and the height of the holder is adjusted so that the dial indicator probe is vertically pressed against the middle section of the guide pillar (or the critical inspection section). The guide pillar is then slowly rotated one full turn by hand, and the dial indicator pointer's swing is observed. The difference between the maximum and minimum readings equals the radial runout of that section (i.e., coaxiality deviation). The deviation value and the direction of the maximum deviation are recorded, which facilitates the detection of mold guide pillar coaxiality. If a deviation is detected, the user marks the deviation point and corrects it using external equipment (stamping device, grinding device).

[0004] However, while the V-groove of the existing mold guide post coaxiality calibrator can achieve initial alignment of the guide post through the inclined surface, without clamping, the guide post only relies on gravity to contact the inner wall of the V-groove, without additional constraint to fix its position. During the rotation of the guide post, if the force is uneven, the guide post will shift laterally or longitudinally within the V-groove, resulting in easy displacement of the guide post and a reduction in detection accuracy. At the same time, all key components of the existing mold guide post coaxiality calibrator are in rigid direct contact without buffer constraint, and the vibration transmission path is completely unobstructed. When there are vibration sources in the workshop (such as the operation of the adjacent punch press, the exhaust of the air compressor, or the passage of a forklift), even if the amplitude is only low, the magnetic base will shake slightly with the vibration. This shaking will be directly transmitted to the dial indicator probe, causing the pointer to jump irregularly (not caused by the coaxiality deviation of the guide post), resulting in unstable detection accuracy. Qualified guide posts are easily misjudged as out of tolerance. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a mold guide post coaxiality calibrator, which has the function of clamping and fixing the guide post, thereby avoiding displacement of the guide post when rotating it, thus improving the detection accuracy. It also has the function of vibration reduction, thereby reducing the impact of vibration on the device detection, thus improving the stability of the device detection accuracy.

[0006] The objective of this utility model is achieved through the following technical solution: The mold guide post coaxiality calibrator includes a worktable, a control device fixedly connected to the top of the worktable, a connecting column fixedly connected to the top of the worktable, a damper fixedly connected to the bottom of the connecting column, a spring fixedly connected between the connecting column and the damper, a support foot fixedly connected to the bottom of the damper, a motor I fixedly connected to one side of the worktable, a left- or right-hand screw I fixedly connected to the output end of motor I, a sliding block I threadedly connected to the left- or right-hand screw I, a slide rail slidably connected inside the sliding block I, a motor II fixedly connected to one side of the sliding block I, a rotating rod fixedly connected to the output end of motor II, a housing fixedly connected to one side of the rotating rod, a motor III fixedly connected to one side of the housing, a left- or right-hand screw II fixedly connected to the output end of motor III, a V-shaped clamping block threadedly connected to the left- or right-hand screw II, a sliding rod slidably connected inside the V-shaped clamping block, and a detection component disposed outside the worktable.

[0007] In one optional embodiment, a through hole is provided on the worktable, and a left- or right-hand screw is rotatably connected to the inside of the worktable through the through hole.

[0008] In one optional embodiment, a through hole two is provided on the sliding block one, and the rotating rod is rotatably connected to the inside of the sliding block one through the through hole two.

[0009] In one optional embodiment, a through hole three is provided on the support foot, and the connecting column is slidably connected to the inside of the support foot through the through hole three.

[0010] In one optional embodiment, the detection assembly includes a motor four fixedly connected to one side of the worktable, a rectangular lead screw one fixedly connected to the output end of the motor four, a sliding block two threadedly connected to the rectangular lead screw one, a motor five fixedly connected to the top of the sliding block two, a rectangular lead screw two fixedly connected to the output end of the motor five, a sliding block three threadedly connected to the rectangular lead screw two, and a digital dial indicator fixedly connected to one side of the sliding block three.

[0011] In one optional embodiment, a through hole four is provided on the worktable, and a rectangular lead screw one is rotatably connected to the inside of the worktable through the through hole four.

[0012] In one optional embodiment, a through hole five is provided on the sliding block two, and the rectangular lead screw two is rotatably connected to the inside of the sliding block two through the through hole five.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The user starts the motor three through the control device to rotate the left and right screw two. The left and right screw two drives the two sets of V-shaped clamping blocks to move towards the middle of the left and right screw two, so that the two sets of V-shaped clamping blocks clamp and fix the guide post, thereby avoiding displacement of the guide post when rotating the guide post, which helps to improve the detection accuracy.

[0014] 2. The user places one end of the guide post into the middle of the V-shaped opening of the V-shaped clamping block, and then starts the motor through the control device to rotate the left and right screws. The left and right screws drive the two sets of sliding blocks to move towards the middle of the left and right screws, which makes it easier for the user to place the other end of the guide post onto another set of V-shaped clamping blocks. This is beneficial for the device to test and calibrate guide posts of different lengths, thus improving the adaptability of the device.

[0015] 3. When vibration is transmitted to this device, it is transmitted to the spring through the support foot. The spring absorbs the vibration peak through elastic deformation. At the same time, the damper converts the vibration energy into heat energy, which increases the amplitude attenuation rate of the vibration frequency, thereby reducing the impact of vibration on the device's detection and thus helping to improve the stability of the device's detection accuracy.

[0022] Please see Figures 1-5This utility model provides an embodiment of a mold guide post coaxiality calibrator, including a worktable 1, a control device 2 fixedly connected to the top of the worktable 1, a connecting post 301 fixedly connected to the top of the worktable 1, a damper 313 fixedly connected to the bottom of the connecting post 301, a spring 314 fixedly connected between the connecting post 301 and the damper 313, a support foot 302 fixedly connected to the bottom of the damper 313, a motor 303 fixedly connected to one side of the worktable 1, a left-hand and right-hand lead screw 304 fixedly connected to the output end of the motor 303, a sliding block 305 threadedly connected to the left-hand and right-hand lead screw 304, and a sliding block 305 slidably connected inside the sliding block 305. The system includes a slide rail 315, a motor 306 fixedly connected to one side of the sliding block 305, a rotating rod 307 fixedly connected to the output end of the motor 306, a housing 308 fixedly connected to one side of the rotating rod 307, a motor 309 fixedly connected to one side of the housing 308, a left-hand and right-hand lead screw 311 fixedly connected to the output end of the motor 309, a V-shaped clamping block 312 threadedly connected to the left-hand and right-hand lead screw 311, a sliding rod 310 slidably connected inside the V-shaped clamping block 312, and a detection component located outside the worktable 1. The control device 2 is electrically connected to motors 401, 303, 306, 309, and 404. The user places one end of the guide post into the middle of the V-shaped opening of the V-shaped clamping block 312. Then, the user starts the motor 303 via the control device 2 to rotate the left and right rotating screw 304. The left and right rotating screw 304 drives the two sets of sliding blocks 305 to move towards the middle of the left and right rotating screw 304, which makes it easier for the user to place the other end of the guide post onto another set of V-shaped clamping blocks 312. This facilitates the testing and calibration of guide posts of different lengths, thus improving the adaptability of the device. Subsequently, the user starts the motor 309 via the control device 2 to rotate the left and right rotating screw 311. The left and right rotating screw 311 drives the two sets of V-shaped clamping blocks 312 to move towards the middle of the left and right rotating screw 311. This allows the two sets of V-shaped clamping blocks 312 to hold and fix the guide post in place, thus preventing displacement of the guide post when it is rotated, which helps to improve the detection accuracy. During detection, the detection component is activated to detect the guide post. If a deviation is detected, the user marks the deviation point, and then removes the guide post and uses external equipment to correct it. When vibration is transmitted to this device, the vibration is transmitted to the spring 314 through the support foot 302. The spring 314 absorbs the vibration peak through elastic deformation, while the damper 313 converts the vibration energy into heat energy, which increases the amplitude attenuation rate of the vibration frequency, thereby reducing the impact of vibration on the device's detection and thus helping to improve the stability of the device's detection accuracy.

[0023] In a preferred embodiment of this utility model, a through hole is provided on the workbench 1, and a left-right rotating lead screw 304 is rotatably connected to the inside of the workbench 1 through the through hole. This facilitates the motor 303 to drive the left-right rotating lead screw 304 to rotate, which in turn facilitates the left-right rotating lead screw 304 to drive the two sets of sliding blocks 305 to translate.

[0024] In a preferred embodiment of this utility model, a through hole 2 is provided on the sliding block 305, and the rotating rod 307 is rotatably connected to the inside of the sliding block 305 through the through hole 2, which facilitates the motor 306 to drive the rotating rod 307 to rotate, and the rotating rod 307 drives the guide post to rotate through the outer shell 308.

[0025] In a preferred embodiment of this utility model, a through hole 3 is provided on the support foot 302, and the connecting column 301 is slidably connected to the inside of the support foot 302 through the through hole 3. This facilitates the spring 314 to absorb the vibration peak through elastic deformation, while the damper 313 converts the vibration energy into heat energy, thereby increasing the amplitude attenuation rate of the vibration frequency and reducing the impact of vibration on the device detection.

[0026] Please see Figure 3 and Figure 5 In this embodiment, the detection assembly includes a motor 401 fixedly connected to one side of the workbench 1, a rectangular lead screw 402 fixedly connected to the output end of the motor 401, a sliding block 403 threadedly connected to the rectangular lead screw 402, a motor 404 fixedly connected to the top of the sliding block 403, a rectangular lead screw 405 fixedly connected to the output end of the motor 404, a sliding block 406 threadedly connected to the rectangular lead screw 405, and a digital dial indicator 407 fixedly connected to one side of the sliding block 406. The control device 2 starts the motor 404 to rotate the rectangular lead screw 405, thereby causing the rectangular lead screw 405 to rotate. The lead screw 405 drives the sliding block 406 to descend, causing the probe of the digital dial indicator 407 to contact the guide post for measurement. Then, the control device 2 starts the motor 306 to drive the rotating rod 307 to rotate, which in turn drives the guide post to rotate through the housing 308. The user then judges the coaxiality of the guide post by reading the digital dial indicator 407. When one part of the guide post has been tested, the control device 2 can start the motor 401 to rotate the rectangular lead screw 402, which in turn drives the sliding block 403 to move, thus facilitating the testing of the coaxiality of different parts of the guide post.

[0027] In a preferred embodiment of this utility model, a through hole four is provided on the workbench 1, and a rectangular lead screw 402 is rotatably connected to the inside of the workbench 1 through the through hole four. This facilitates the rotation of the rectangular lead screw 402 by the motor four 401, which in turn facilitates the translation of the sliding block two 403 by the rectangular lead screw 402, thereby facilitating the detection of the coaxiality of different parts of the guide post.

[0028] In a preferred embodiment of this utility model, a through hole five is provided on the sliding block two 403, and the rectangular lead screw two 405 is rotatably connected to the inside of the sliding block two 403 through the through hole five, which is conducive to the motor five 404 driving the rectangular lead screw two 405 to rotate, which is conducive to the rectangular lead screw two 405 driving the sliding block three 406 to rise and fall.

[0029] During operation, the user places one end of the guide post into the center of the V-shaped opening of the V-shaped clamping block 312. Then, the control device 2 starts the motor 303, causing the left and right rotating screw 304 to rotate. The left and right rotating screw 304 drives the two sets of sliding blocks 305 to move towards the center of the left and right rotating screw 304. This facilitates the user placing the other end of the guide post onto another set of V-shaped clamping blocks 312, thus enabling the device to test and calibrate guide posts of different lengths, thereby improving the adaptability of the device. Subsequently, the user... The control device 2 starts motor 309 to rotate the left and right rotating lead screw 311. The left and right rotating lead screw 311 drives two sets of V-shaped clamping blocks 312 to move towards the middle of the left and right rotating lead screw 311, thereby clamping and fixing the guide post with the two sets of V-shaped clamping blocks 312, thus preventing the guide post from shifting when rotating, which helps to improve the detection accuracy. During detection, the control device 2 starts motor 404 to rotate the rectangular lead screw 405, thereby causing the rectangular lead screw 405 to drive the sliding block 406 to descend, thus... The probe of the digital dial indicator 407 contacts the guide post for measurement. Then, the control device 2 starts the motor 306 to drive the rotating rod 307 to rotate, which in turn drives the guide post to rotate through the housing 308. The user then judges the coaxiality of the guide post by reading the digital dial indicator 407. After testing one part of the guide post, the control device 2 starts the motor 401 to rotate the rectangular lead screw 402, which in turn drives the sliding block 403 to move, thus facilitating the testing of the coaxiality of different parts of the guide post. If a deviation is detected, the user marks the deviation point and then removes the guide post for external correction. When vibration is transmitted to this device, it is transmitted to the spring 314 through the support foot 302. The spring 314 absorbs the vibration peak through elastic deformation, while the damper 313 converts the vibration energy into heat energy, increasing the amplitude attenuation rate of the vibration frequency, thereby reducing the impact of vibration on the device's detection and improving the stability of the device's detection accuracy.
