Description

Technical Field

[0001] This invention relates to the field of coaxiality testing technology, specifically to a coaxiality testing device for tungsten carbide molds. Background Technology

[0002] Currently, existing coaxiality testing devices install the mold by passing a reference shaft through a hole in the tungsten carbide mold. However, this method is difficult to adapt well when the hole diameter varies due to different mold sizes. A tungsten carbide mold coaxiality testing device with application number CN202322713454.0 includes a base plate with mounting seats symmetrically fixed on the top of the base plate. By selecting different through shafts, the device is fixed inside the threaded groove at different positions according to the different positions of the second mounting plate on the through shaft, thus achieving the effect of adapting to tungsten carbide molds with different hole diameters.

[0003] While this device possesses the aforementioned advantages, it still suffers from the following drawbacks in practical use: 1) When using this device, two mounting plates on the left and right sides and a through shaft are needed to clamp the tungsten carbide mold. The tungsten carbide mold needs to be repeatedly disassembled and put away, which makes the actual testing operation time-consuming, labor-intensive and inefficient. 2) When using this device, the dial indicator probe needs to be manually adjusted to make it contact the tungsten carbide mold. Furthermore, the probe is not protected during testing and can easily enter the grooves on the surface of the tungsten carbide mold, causing damage to the probe and affecting the testing work.

[0004] Therefore, it is necessary to address the problems that still exist in the existing devices. Summary of the Invention

This device solves the problems of existing tungsten carbide mold coaxiality testing devices, which require repeated disassembly of the mounting plates and through shafts on both sides when handling tungsten carbide molds.

[0016] Beneficial effects This invention provides a device for detecting the coaxiality of tungsten carbide molds. Compared with the prior art, it has the following advantages: (1) By setting up a pick-up and put-down mechanism, two abutment wheels move along the waist, so that the time distance between them gradually decreases as they rise, thereby lifting the tungsten steel mold. At the same time, the descent of the rotating wheel abuts the top of the tungsten steel mold, completing the rapid clamping of the tungsten steel mold. Then, the drive motor drives the tungsten steel mold to rotate for inspection. At the same time, the transmission wheel makes the conveyor belt arc-shaped to wrap the tungsten steel mold. Then, through the conveying action of the conveyor belt, the tungsten steel mold can be continuously inspected, which not only makes the inspection work more convenient, but also improves the inspection efficiency.

[0017] (2) By setting up a guide component, the reciprocating motor drives the lead screw to rotate, and the lead screw and the slide plate are connected by a thread, so that the slide plate can drive the abutment plate to move along the waist side through the folding plate. At the same time, the setting of the rotating groove can facilitate the rotation of the abutment wheel to adapt to the rotation of the tungsten steel mold. Meanwhile, one side of the folding plate coincides with the left and right sides of the slide groove, which can provide a larger movement path so that the abutment wheel can lift tungsten steel molds with different outer diameters, thereby improving the applicability of the device.

[0018] (3) By setting up a linkage unit, the contact action between the abutment plate and the sliding connecting plate is utilized. When the abutment wheel approaches the tungsten steel mold, the connecting plate disengages from the contact, causing the slide bar to fall and drive the rotating wheel to approach the tungsten steel mold synchronously, thereby completing the clamping action of the tungsten steel mold. The use of triangular clamping can improve the stability of the tungsten steel mold. At the same time, the retraction of the telescopic rod can make the rotating wheel descend at a uniform speed, avoiding a large impact on the tungsten steel mold, which would damage both of them and affect the testing work.

[0019] (4) By setting an adjustment module, when the outer diameter of the tungsten carbide mold to be tested changes, the pin rod changes its relative position inside the through groove, thereby changing the length of the traction rope inside the through groove, so as to control the descent distance of the wheel. This not only keeps the traction rope taut, but also can be adapted to tungsten carbide molds with different outer diameters, thereby improving the range of applications.

[0020] (5) By setting up a detection component, the probe of the portable detector can automatically fit onto the surface of the tungsten steel mold by extending and retracting the output end of the lifting rod and rotating the output end of the rotary cylinder, thereby improving detection efficiency and saving time and effort in the detection work. At the same time, a measuring instrument covering the detection range of the detector is set under the rotary cylinder to detect whether the tungsten steel surface is flat. In addition, the rotary cylinder drives the detector to rotate, which can prevent the probe of the detector from entering the grooves on the tungsten steel surface, causing damage to the detector and affecting the detection work.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-5 This invention provides a technical solution: a device for detecting the coaxiality of tungsten carbide molds. Example 1: Refer to the attached instruction manual Figure 1 Appendix Figure 2 Appendix Figure 3 ; The system includes a base 1, with a lifting and placing mechanism on its exterior. This mechanism includes two inclined columns 2, which are angled and provide an isosceles path for the movement of the abutment rollers 3. This allows the two abutment rollers 3 to move closer together as they move upwards, thus lifting the tungsten carbide mold. The distance between the two abutment rollers 3 can be adjusted to accommodate tungsten carbide molds of different outer diameters. As an effective method, two sets of inclined columns 2 can be installed on both the left and right sides above the base 1 to support the abutment rollers 3 and the transmission wheel 11, respectively. Abutment rollers 3 are installed on the exterior of each of the two inclined columns 2. These abutment rollers 3 can both lift the tungsten carbide mold from below and can also be rotated to adapt to different mold diameters. The rotating abutment roller 3 is made of pressure-resistant and wear-resistant material with a smooth surface treatment, thus supporting only the tungsten carbide mold and preventing excessive contact friction between them, thereby avoiding problems that affect the rotation of the tungsten carbide mold. A guide component 4 is provided on the body of the inclined column 2. A conveyor belt 5 is provided between the outer surfaces of the two abutment rollers 3. The conveyor belt 5 can transport the tungsten carbide mold to achieve continuous inspection. The upper transmission length of the conveyor belt 5 is greater than the axial length of the tungsten carbide mold. A detection component 6 is provided above the conveyor belt 5. A rotating wheel 7 is provided directly above the conveyor belt 5. The rotating wheel 7 and the two abutment rollers 3 are arranged in an isosceles triangle. The upper part abuts against the tungsten carbide mold, forming a triangular clamp with two abutment rollers 3 to improve the stability of the tungsten carbide mold. Friction also drives the tungsten carbide mold to rotate for coaxiality testing. As a preferred method, a rubber ring can be fitted onto the surface of the roller 7 via an interference fit. The contact friction between the rubber and the tungsten carbide mold increases, facilitating better rotation of the tungsten carbide mold by the roller 7 without causing surface scratches. A drive motor 8 is fixedly connected to the outer surface of the roller 7, and the drive motor 8 is electrically connected to an external control circuit to drive the roller 7 to rotate. The outer surface of the inclined column 2... A ladder frame 9 is fixedly connected. The ladder frame 9 is trapezoidal in shape. By reducing its thickness, the range of motion of the abutment wheel 3 is increased. A rotating rod 10 is rotatably connected to the outer surface of the ladder frame 9. The rotating rod 10 can be connected to an external drive device to drive the conveyor belt 5 to rotate. A transmission wheel 11 is fixedly connected through the outer surface of the rotating rod 10. An arc-shaped groove is opened on the outer surface of the transmission wheel 11. The arc-shaped groove on the transmission wheel 11 makes the conveyor belt 5 arc-shaped in shape. The curvature of the arc-shaped groove is adapted to the curvature of the tungsten steel mold to wrap the tungsten steel mold, thereby improving the stability of the tungsten steel mold during transportation. The conveyor belt 5 is connected to the transmission wheel 11 through the groove.

[0025] In this embodiment, the tungsten carbide mold to be tested is first placed on the conveyor belt 5, with the shaft length of the tungsten carbide mold aligned with the conveyor belt 5. The conveyor belt 5 then transports the tungsten carbide mold, positioning it between the abutment roller 3 and the rotating roller 7. The abutment rollers 3 on both sides then move upwards along the ridge of the inclined column 2, gradually reducing the distance between them. As they rise, the abutment rollers 3 lift the tungsten carbide mold, freeing it from the restriction of the conveyor belt 5. Simultaneously, the drive motor 8 drives the rotating roller 7 to descend synchronously. The rotating roller 7 abuts against the top of the tungsten carbide mold, creating a triangular clamp that stably suspends the mold. The drive motor 8 then drives the rotating roller 7 to rotate. Through friction with the tungsten carbide mold, the rotating roller 7 causes the mold to rotate synchronously. Since the surfaces of the abutment rollers 3 on both sides are smooth, they either rotate synchronously with the mold or do not affect its rotation. Thus, the coaxiality of the tungsten carbide mold can be detected simply by its rotation.

[0026] Example 2: Based on Example 1, refer to the appendix of the instruction manual. Figure 1 Appendix Figure 2 ; The guide assembly 4 includes a slide 41, which is opened along the ridge of the inclined column 2, allowing the abutment wheel 3 to move along the ridge of the inclined column 2. The slide 41 is opened on the outer surface of the inclined column 2. A slide plate 42 is slidably connected inside the slide 41. The external dimensions of the slide plate 42 are adapted to the internal dimensions of the slide 41 to improve the stability of the movement of the abutment wheel 3. A folding plate 43 is fixedly connected to the outer surface of the slide plate 42. One side of the folding plate 43 coincides with the slide 41, providing a larger movement path for the abutment wheel 3, thus adapting it to tungsten carbide molds with different outer diameters. A rotating groove 45 is opened at one end of the folding plate 43, providing rotation space for the abutment wheel 3 so that the abutment wheel 3 can rotate to adapt to the rotation of the tungsten carbide mold. At the same time, the shaft end of the abutment wheel 3 is embedded in both sides of the rotating groove 45 through bearings, so that... When the abutment wheel 3 provides support, the bearing allows the abutment wheel 3 to rotate smoothly following the tungsten carbide mold. The outer surface of the abutment wheel 3 is rotatably connected to the inside of the rotating groove 45. The inside of the rotating groove 45 is rotatably connected to the support rod 46. The outer surface of the support rod 46 is fixedly connected to the body of the abutment wheel 3. The inside of the sliding groove 41 is fixedly connected to the reciprocating motor 47, which is made of servo motor and is electrically connected to the external control circuit. The output end of the reciprocating motor 47 is fixedly connected to the lead screw 48 through the coupling. The outer surface of the lead screw 48 is rotatably connected to the inside of the sliding groove 41. The outer surface of the lead screw 48 is threadedly connected to the body of the sliding plate 42. By rotating the lead screw 48 in both directions, the sliding plate 42 can reciprocate inside the sliding groove 41, thereby controlling the abutment wheel 3 to lift or reset the tungsten carbide mold.

[0027] In this embodiment, when the abutment wheel 3 needs to lift the tungsten carbide mold, the reciprocating motor 47 drives the lead screw 48 to rotate in the forward direction. Through the threaded connection between the lead screw 48 and the slide plate 42, the slide plate 42 slides along the axis of the lead screw 48 to one side inside the slide groove 41. Thus, the abutment wheel 3 is driven to move upward along the ridge line of the inclined column 2 through the folding plate 43. When the abutment wheel 3 contacts the tungsten carbide mold, the abutment wheel 3 can rotate to adapt to the rotation of the tungsten carbide mold through the cooperation of the rotating groove 45 and the support rod 46. After the detection is completed, the reciprocating motor 47 drives the lead screw 48 to reverse, so that the folding plate 43 drives the abutment wheel 3 to move in the opposite direction and reset, so that the tungsten carbide mold falls back onto the conveyor belt 5 and is then unloaded by the conveyor belt 5.

[0028] Example 3: Based on Example 2, refer to the appendix of the instruction manual. Figure 2 Appendix Figure 3 ; A linkage unit 44 is provided on the outside of the folding plate 43. The linkage unit 44 includes a slide bar 441, which supports the drive motor 8 and the rotating wheel 7. The outer surface of the slide bar 441 is slidably connected to the body of the ladder frame 9. The outer surface of the slide bar 441 is fixedly connected to the outer surface of the drive motor 8. A rope loop 442 is fixedly connected to the top of the slide bar 441, and a traction rope is wound around the rope loop 442. Two fixed frames 443 are provided on the outside of the slide bar 441. The outer surfaces of the two fixed frames 443 are fixedly connected to the top of the ladder frame 9. Two fixed pulleys 444 are fixedly connected to the outer surfaces of the fixed frames 443. The traction rope is arranged in an S-shape on the two fixed pulleys 444, so that the two fixed pulleys 444 can change the orientation of the traction rope to be parallel to the ridge line of the inclined column 2, and can also stretch the traction rope to keep it taut to maintain the traction effect on the slide bar 441. The outer surfaces of the traction rope are movably connected to the outer surfaces of the two fixed pulleys 444 respectively. Two connecting plates 445 are provided on one side of the outer surface of the slider 441. The outer surface of one connecting plate 445 is fixedly connected to the outer surface of the inclined column 2. The body of one connecting plate 445 has a through rope hole 446, which facilitates the insertion of the traction rope. One end of the traction rope is inserted into the inside of the rope hole 446. The outer surface of the other connecting plate 445 is slidably connected to the outer surface of the inclined column 2. One end of the traction rope is fixedly connected to the outer surface of the other connecting plate 445. The outer surfaces of the two connecting plates 445 are fixedly connected by a telescopic rod 447. The telescopic rod 447 can be made of a spring rod to maintain the tension of the traction rope. As a preferred method, the output end of the telescopic rod 447 is provided with a sliding damping function, so that the slider 441 can drive the abutment wheel 3 to move and descend. The outer surface of the other connecting plate 445 is movably connected to an abutment plate 448, and the outer surface of the abutment plate 448 is fixedly connected to the outer surface of the folding plate 43.

[0029] In this embodiment, when the folding plate 43 drives the abutment wheel 3 to reset, the abutment plate 448 moves synchronously. Through the abutment action of the abutment plate 448 and the connecting plate 445 on one side, the connecting plate 445 on one side moves synchronously, thereby pulling one end of the traction rope. Through the support and reversing action of the fixed pulley 444, and through the action of the rope loop 442 and the slide bar 441, the drive motor 8 and the rotating wheel 7 rise synchronously and disengage from the abutment action on the tungsten steel mold. When the folding plate 43 drives the abutment wheel 3 to lift the tungsten steel mold, the connecting plate 445 on one side disengages from the abutment action of the abutment plate 448. The slide bar 441, the drive motor 8, and the rotating wheel 7 descend under the action of gravity, synchronously abutting and clamping the tungsten steel mold. During this process, the output end of the telescopic rod 447 retracts at a constant speed through the damping action, so that the rotating wheel 7 descends at a constant speed to avoid impacting the tungsten steel mold.

[0030] Example 4: Based on Example 3, refer to the appendix of the instruction manual. Figure 2 Appendix Figure 4 ; An adjustment module 449 is externally mounted on the traction rope. The adjustment module 449 includes a straight bar 4491. The body of the straight bar 4491 has a through groove 4492, and the inside of the through groove 4492 is connected to an opening 4493. The opening 4493 is located on the body of the straight bar 4491 and is in a through-hole state. Two fixed plates 4494 are fixedly connected inside the through groove 4492. The length of the fixed plates 4494 is less than the inner length of the through groove 4492, thus forming an S-shaped path inside the through groove 4492. The ends of the fixed plates 4494 are chamfered to prevent cutting the traction rope and causing it to break. A pin 4495 is movably connected inside the through groove 4492. The pin 4495 can drive the traction rope into the through groove 4492 through the opening 4493. The portion of the pin 4495 inside the through groove 4492 has two mirror-image cut surfaces, allowing the thickness of this portion of the pin to adapt to the S-shaped path. The outer surface is fixedly connected to the outer surface of the traction rope. As a preferred method, the traction rope is divided into two sections. One section of the traction rope is fixedly connected at both ends to the outer surfaces of the sliding connecting plate 445 and the straight bar 4491, respectively. One end of the other section of the traction rope is wrapped around the rope loop 442, and the other end is fixed to the surface of the pin 4495. The outer surface of the fixed plate 4494 and the inside of the through groove 4492 are both provided with slots 4496. The slots 4496 on both sides are arc-shaped, and the arc is adapted to the arc of the pin 4495. The spacing is adapted to the outer diameter of the pin 4495. The outer surface of the pin 4495 is engaged with the inside of the slots 4496 on both sides. The outer surface of the pin 4495 is threaded with a nut 4497. The nut 4497 ​​improves the stability of the pin 4495 and the traction rope through the abutment action. The outer surface of the nut 4497 ​​is movably connected to the outer surfaces of the fixed plate 4494 and the straight bar 4491, respectively.

[0031] In this embodiment, when the outer diameter of the tungsten carbide mold changes, the relative position of the pin 4495 inside the through groove 4492 is changed to tighten or release the other end of the traction rope, thereby adjusting the descent distance of the slide bar 441. Then, the pin 4495, which has been adjusted, is rotated so that the two sides of its rod body enter the slot 4496 to complete the engagement of the pin 4495. Then, the nut 4497 ​​is screwed onto the pin 4495 to complete the fixation of the pin 4495.

[0032] Example 5: Based on Example 1, refer to the appendix of the instruction manual. Figure 1 Appendix Figure 5 ; The detection component 6 includes a bracket 61, the outer surface of which is fixedly connected to the outer surface of the ladder 9. A lifting rod 62 is fixedly connected to the outer surface of the bracket 61. The lifting rod 62 is made of an electric push rod and is electrically connected to an external control circuit. A rotary cylinder 63 is fixedly connected to the output end of the lifting rod 62. The rotary cylinder 63 is connected to an external control circuit. A detector 64 is fixedly connected to the output end of the rotary cylinder 63. The detector 64 is made of an existing dial indicator and multiple detectors are equidistantly arranged along the conveying direction of the conveyor belt 5. A support plate 65 is fixedly connected to the bottom of the rotary cylinder 63. A measuring instrument 66 is fixedly connected to the bottom of the support plate 65. The measuring instrument 66 is made of an existing laser rangefinder or ultrasonic rangefinder and is electrically connected to an external control circuit. The monitoring range of the measuring instrument 66 covers the detection range of the detector 64.

[0033] In this embodiment, after the tungsten carbide mold to be tested is lifted by the abutment wheel 3 and clamped by the rotating wheel 7, the output end of the lifting rod 62 extends, driving the detector 64 and measuring instrument 66 to descend via the rotary cylinder 63. Then, the output end of the rotary cylinder 63 rotates, causing the detection needle of the detector 64 to come into contact with the surface of the tungsten carbide mold. Coaxiality is detected by rotating the tungsten carbide mold. Multiple comparisons are used to improve the accuracy of the test and avoid the problem of the detection work being affected by the damage of a single detector 64. During the rotation of the tungsten carbide mold, the measuring instrument 66 monitors the distance between itself and the surface of the tungsten carbide mold. When there is a large depression or protrusion on the surface of the tungsten carbide mold, the output end of the rotary cylinder 63 drives the detector 64 to rotate, causing the detection needle to disengage from the tungsten carbide surface, thereby avoiding the problem of the detection needle being damaged and affecting the detection work.
