Description

Technical Field

[0001] This utility model relates to the field of mold plate processing and testing technology, and in particular to a device for detecting the side hole diameter of a mold plate. Background Technology

[0002] The mold base plate is an important component of the mold, and the machining accuracy of its side holes directly affects the assembly accuracy and performance of the mold. During the production process of the mold base plate, it is necessary to strictly inspect the hole diameter, hole spacing, and hole perpendicularity.

[0003] Chinese utility model patent CN223389103U discloses a multi-specification adaptable mold frame aperture detection device. Its specific structure includes a detection base plate, a clamping device slidably connected to the base plate, and detection devices slidably arranged on both sides of the base plate. Each detection device includes a detection disc, on which a mandrel detection assembly is slidably arranged. The mandrel detection assembly includes a mandrel body and a fixing groove formed on the mandrel body. Two fixing threaded openings are arrayed within the fixing groove. The detection disc has fixing through-holes of a size matching the two fixing threaded openings. Fixing nuts, which are threaded into the two fixing threaded openings, are threaded onto the fixing through-holes. The detection devices are symmetrically arranged on the base plate, which has a sliding groove. The clamping device is slidably arranged within the sliding groove and can move along the length of the sliding groove.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: In the above-mentioned equipment, the mold frame is clamped by a clamping device, the mandrel body is switched by detecting the rotation of the motor, the detection cylinder retracts and inserts the mandrel body into the hole of the base plate, and after the detection is completed, the clamping device is moved to drive the base plate to the detection device on the other side for adjustment and insertion again, thereby achieving the effect of simultaneous double-sided detection of the holes on the surface of the base plate. However, if the equipment needs to detect different mold frame hole diameters, the mandrel body needs to be disassembled by a nut to replace the mandrel body adapted to the detection equipment, which is cumbersome and reduces the detection efficiency. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a device for detecting the side hole diameter of a mold plate.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a side hole diameter detection device for a mold plate, comprising an operating table, a through hole through the operating table, a sliding block slidably disposed within the through hole, a driving component for moving the sliding block on the operating table, a U-shaped mounting bracket fixed to the top of the operating table, a first electric push rod disposed on the U-shaped mounting bracket, a mounting plate fixed to the lower end of the first electric push rod, a rotating rod rotatably mounted on the bottom of the mounting plate, a connecting column fixed to the lower end of the rotating rod, a contact probe disposed at the lower end of the connecting column, a transmission component for driving the rotating rod to rotate on the mounting plate, and a power component for driving the contact probe to rotate on the rotating rod.

[0007] By adopting the above technical solution, when the operator needs to inspect the aperture of the mold plate, the mold plate is first placed on the sliding block. The operator then drives the sliding block to move using the drive assembly. The sliding block moves the mold plate. When the aperture of the mold plate moves to below the contact probe, the operator controls the first electric push rod. The first electric push rod starts and moves the mounting plate. The mounting plate moves the rotating rod, which in turn moves the connecting column. The connecting column moves the contact probe closer to the aperture of the mold plate. When the contact probe descends to the desired position, the operator rotates the contact probe using the power assembly. This causes the contact probe to come into contact with the inner wall of the aperture of the mold plate and undergo a slight displacement, thereby achieving the aperture inspection of the mold plate. This application changes the traditional method of disassembling the mandrel body with a nut to replace the inspection component adapted to different apertures, simplifying the operation steps and improving the inspection efficiency.

[0008] Furthermore, the power assembly includes an upper fixed plate fixedly sleeved on the rotating rod, a ball block fixed to the lower end of the connecting column, and an arc-shaped ring slidably sleeved on the outside of the ball block. The diameter of the opening of the arc-shaped ring is smaller than the diameter of the ball block. The power assembly also includes a second electric push rod hinged to the bottom of the upper fixed plate and a lower fixed plate fixedly sleeved on the arc-shaped ring. The end of the second electric push rod away from the upper fixed plate is hinged to the top of the lower fixed plate, and the bottom of the lower fixed plate is fixedly connected to the contact probe.

[0009] By adopting the above technical solution, the staff controls the second electric push rod, which starts and drives the lower fixed plate to rotate. The lower fixed plate deflects around the ball block as the center, thereby driving the contact probe to rotate at multiple angles, so as to achieve contact between the contact probe and the inner wall of the hole in the mold plate.

[0010] Furthermore, the drive assembly includes a lead screw rotatably mounted in a through hole and threadedly connected to a sliding block, a limiting rod fixed in the through hole, and a drive motor fixed to the side wall of the operating table and driving the lead screw to rotate. The limiting rod passes through the sliding block and slides with the sliding block. The sliding block is provided with a clamping mechanism for fixing the mold plate.

[0011] By adopting the above technical solution, the staff controls the drive motor, which starts and drives the lead screw to rotate. Since the limit rod and the sliding block are in sliding engagement and the sliding block is threadedly connected to the lead screw, the sliding block moves along the axis of the lead screw, thereby enabling the sliding block to drive the mold plate to move.

[0012] Furthermore, the clamping mechanism includes a pushing assembly, which includes a sliding plate slidably disposed on the top of the sliding block, a limiting plate fixed to the side wall of the sliding plate, and a fixing block fixed to the side wall of the sliding block. There are two fixing blocks. The pushing assembly also includes a fixing rod fixed between the two fixing blocks, a side plate fixed to the side wall of the sliding plate, and a third electric push rod fixed to the side wall of the sliding block away from the limiting plate and driving the side plate to move. The fixing rod passes through the limiting plate and slides with the limiting plate. The clamping mechanism also includes a clamping assembly for clamping the mold plate.

[0013] By adopting the above technical solution, the operator places the mold plate on the sliding block and clamps it with the clamping assembly. Then, the operator drives the sliding block to move the mold plate below the contact probe. When there is a large deviation between the aperture of the mold plate and the contact probe, the operator controls the third electric push rod. The third electric push rod starts and drives the side plate to move. The side plate drives the sliding plate to move, so that the aperture of the mold plate corresponds to the position of the contact probe.

[0014] Furthermore, the clamping assembly includes a positioning rod fixed to the top of the slide plate, a clamping plate slidably disposed on the positioning rod, a fixing plate fixed to the top of the positioning rod, a screw rotatably mounted on the top of the clamping plate and threadedly connected to the fixing plate, and a turntable fixed to the upper end of the screw.

[0015] By adopting the above technical solution, the workers place the mold frame plate on the slide plate and rotate the turntable. Since the clamping plate slides on the positioning rod and the screw is threadedly connected to the fixing plate, the screw rotates and drives the clamping plate to move closer to the mold frame plate, thereby fixing the mold frame plate.

[0016] Furthermore, a rubber pad is fixed to the bottom of the clamping plate.

[0017] By adopting the above technical solution, the rubber pad is made of rubber, which has a certain degree of flexibility and resilience, increasing the friction between the clamping plate and the mold plate, and ensuring the fixing effect.

[0018] Furthermore, the transmission assembly includes a plate fixed to the top of the mounting plate, a worm gear fixedly sleeved on the rotating rod, a worm rotatably mounted on the plate and meshing with the worm gear, and a transmission motor fixed to the bottom of the mounting plate and driving the worm to rotate.

[0019] By adopting the above technical solution, the staff controls the transmission motor, which starts and drives the worm gear fixed to its output shaft, the worm wheel meshing with the worm gear, the rotating rod fixed to the worm wheel, the connecting column fixed to the rotating rod, and the ball block fixed to the connecting column to rotate. This causes the ball block to drive the contact probe to rotate, and the staff can inspect the inner wall of the hole in the mold plate as needed.

[0020] Furthermore, a bellows sleeved on the outside of the lead screw is fixed between the sliding block and the inner walls on both sides of the through hole.

[0021] By adopting the above technical solution, the bellows reduces the probability of dust and other debris adhering to the lead screw, thus ensuring transmission efficiency.

[0022] In summary, this utility model has the following beneficial effects: When the operator needs to inspect the aperture of the mold plate, the mold plate is first placed on the sliding block. The operator drives the sliding block to move through the drive assembly, and the sliding block drives the mold plate to move. When the aperture of the mold plate moves to below the contact probe, the operator controls the first electric push rod. The first electric push rod starts and drives the mounting plate to move. The mounting plate drives the rotating rod to move, and the rotating rod drives the connecting column to move. The connecting column drives the contact probe to move towards the aperture of the mold plate. When the contact probe descends to the required position, the operator rotates the contact probe through the power assembly, so that the contact probe abuts against the inner wall of the aperture of the mold plate and undergoes a slight displacement, thereby realizing the inspection of the aperture of the mold plate.

The worm 33 is rotatably mounted on the plate body 31 and meshes with the worm gear 32. The drive motor 34 is fixed to the bottom of the mounting plate 15 and drives the worm 33 to rotate.

[0029] A power assembly 4 is mounted on the rotating rod 16 and is used to drive the contact probe 18 to rotate. The power assembly 4 includes an upper fixed plate 41, a ball block 42, an arc ring 43, a second electric push rod 44, and a lower fixed plate 45. The upper fixed plate 41 is fixedly sleeved on the rotating rod 16, and the ball block 42 is fixed to the lower end of the connecting column 17. The arc ring 43 is slidably sleeved on the outside of the ball block 42, and the diameter of the opening of the arc ring 43 is smaller than the diameter of the ball block 42.

The end of the second electric push rod 44 away from the upper fixed plate 41 is hinged to the top of the lower fixed plate 45, and the bottom of the lower fixed plate 45 is fixedly connected to the contact probe 18.

[0030] A clamping mechanism 5 is mounted on the sliding block 12 and used to fix the mold plate. The clamping mechanism 5 includes a pushing assembly 51 and a clamping assembly 52. ​​The pushing assembly 51 includes a sliding plate 511, a limiting plate 512, a fixing block 513, a fixing rod 514, a side plate 515, and a third electric push rod 516. The sliding plate 511 is slidably mounted on the top of the sliding block 12, and the limiting plate 512 is fixed to the side wall of the sliding plate 511. The fixing block 513 is fixed to the side wall of the sliding block 12, and there are two fixing blocks 513. The fixing rod 514 is fixed between the two fixing blocks 513, and the side plate 515 is fixed to the side wall of the sliding plate 511. The third electric push rod 516 is fixed to the side wall of the sliding block 12 away from the limiting plate 512, and the third electric push rod 516 drives the side plate 515 to move. In this embodiment, the fixing rod 514 passes through the limiting plate 512 and slides with the limiting plate 512. The fixing rod 514 is used to limit the movement direction of the slide plate 511 and prevent the slide plate 511 from deviating.

[0031] The clamping assembly 52 is used to clamp the mold plate. The clamping assembly 52 includes a positioning rod 521, a clamping plate 522, a fixing plate 523, a screw 524, and a turntable 525. The positioning rod 521 is fixed to the top of the slide plate 511, and the clamping plate 522 is slidably disposed on the positioning rod 521. The fixing plate 523 is fixed to the top of the positioning rod 521, the screw 524 is rotatably mounted on the top of the clamping plate 522 and threadedly connected to the fixing plate 523, and the turntable 525 is fixed to the upper end of the screw 524.

[0032] When the operator needs to inspect the hole diameter of the mold plate, the mold plate is first placed on the slide plate 511 and the turntable 525 is rotated. Since the clamping plate 522 slides on the positioning rod 521 and the screw 524 is threadedly connected to the fixing plate 523, the screw 524 rotates while driving the clamping plate 522 to move closer to the mold plate, thereby fixing the mold plate. Then the operator controls the drive motor 23, which starts and drives the lead screw 21 to rotate. Since the limit rod 22 slides with the sliding block 12 and the sliding block 12 is threadedly connected to the lead screw 21, the sliding block 12 moves along the axis of the lead screw 21, thereby moving the mold plate. When the mold plate moves below the contact probe 18, the operator controls the third electric push rod 516. The third electric push rod 516 starts and moves the side plate 515. The side plate 515 moves the slide plate 511, and the slide plate 511 moves the mold plate, so that the aperture of the mold plate corresponds to the position of the contact probe 18. The operator controls the first electric push rod 14. The first electric push rod 14 starts and moves the mounting plate 15. The mounting plate 15 moves the rotating rod 16, and the rotating rod 16 moves the connecting column 17. The connecting column 17 moves the contact probe 18 towards the aperture of the mold plate. When the contact probe 18 descends to the desired position, the operator controls the second electric push rod 44. The second electric push rod 44 starts and rotates the lower fixed plate 45. The lower fixed plate 45 deflects around the ball block 42, thereby causing the contact probe 18 to rotate at multiple angles. The contact probe 18 abuts against the inner wall of the aperture of the mold plate and undergoes slight displacement, thereby realizing the aperture detection of the mold plate.

[0033] In this embodiment, a rubber pad 6 is fixed to the bottom of the clamping plate 522. The rubber pad 6 is made of rubber, possessing a certain degree of flexibility and resilience, increasing the friction between the clamping plate 522 and the mold plate, thus ensuring a secure fixation. In this embodiment, a bellows 7 is fixed between the sliding block 12 and the inner walls on both sides of the through hole 11, and the bellows 7 is sleeved on the outside of the lead screw 21. The bellows 7 reduces the probability of dust and other debris adhering to the lead screw 21, ensuring transmission efficiency.
