Description

Technical Field

[0001] This invention relates to the field of laser measurement technology, specifically to a deformation measurement mechanism for heat treatment processing of square rails. Background Technology

[0002] When the surface of a material is affected by temperature, it will show slight deformation. Slight deformation cannot be measured directly with the naked eye and requires a measuring tool containing a laser emitter. By changing the light path emitted by the laser emitter, the slight deformation can be amplified, which helps to measure the slight deformation. For example, the micro deformation measuring instrument disclosed in CN210952723U can measure the slight deformation of materials with high measurement accuracy and little influence from external factors.

[0003] Square rails are a type of rectangular track. During production, they undergo heat treatment to increase their wear resistance and hardness, ensuring stability during use. However, metal materials are prone to slight deformation during heat treatment. If the size of the deformation is not precisely controlled, the heat-treated square rails may become unusable. To measure the slight deformation of square rails after heat treatment, a deformation measuring mechanism for heat treatment of square rails is required.

[0004] The existing deformation measurement mechanism for heat treatment of square rails cannot improve the efficiency and effect of measurement. This is because the existing deformation measurement mechanism for heat treatment of square rails cannot quickly clamp and measure, resulting in poor measurement efficiency.

[0005] Therefore, a deformation measuring mechanism for heat treatment of square rails is needed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a deformation measuring mechanism for heat treatment of square rails, so as to solve the problem of poor efficiency in the measurement of existing deformation measuring mechanisms for heat treatment of square rails mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A deformation measuring mechanism for heat treatment of square rails includes a base and a support seat supported thereon by a leveling assembly. The support seat has a level bubble for observing the rail's tilt. The support seat has a clamping groove containing a clamping mechanism, which includes a set of rollers for clamping the square rail. The upper surface of the support seat has two sets of protruding seats, each connected to a lead screw and a limiting shaft. The lead screw and limiting shaft are parallel to each other. One end of the lead screw is connected to a bearing of the corresponding protruding seat. A motor is also mounted on the upper surface of the support seat, with its output end coaxially connected to the other end of the lead screw. The bearing of the other end of the lead screw passes through the corresponding protruding seat. A support plate is positioned above the support seat. Support frames are fixedly connected to both sides of the lower end of the device. Each support frame is penetrated by a lead screw and a limiting shaft, and the lead screw is also threadedly connected to the support frame it penetrates. A laser measuring mechanism is mounted on the support plate, including a CCD for receiving light. The clamping mechanism also includes a mounting groove inside the support base with openings at both ends within the clamping slot. Clamping components are slidably connected to the two openings of the mounting groove. A roller assembly is provided at the end of each clamping component located within the clamping slot. The clamping mechanism also includes a follower gear plate connected to the ends of the two clamping components extending into the mounting groove. A transmission gear meshes with the two follower gear plates, and the transmission gear is limited and sleeved on the lower end of the positioning shaft. The clamping mechanism includes a truncated cone-shaped groove at the top of the mounting slot, with the upper end of the positioning shaft connected to the inner top of the mounting slot via a one-way bearing. Magnetic plates are provided on the sides of the clamping member corresponding to the mounting slot, with opposite faces of the two magnetic plates having the same magnetic poles. The lower end of the positioning shaft is truncated cone-shaped, and the upper surface of the transmission gear has a truncated cone-shaped groove that matches the lower end of the positioning shaft. The lower end of the positioning shaft and the truncated cone-shaped groove on the upper surface of the transmission gear are positioned opposite each other. The transmission gear and the positioning shaft are coaxially arranged. The clamping mechanism also includes an inner groove within the mounting slot, connected to the lower end of the positioning shaft via a one-way bearing. The inner diameter of the inner groove is larger than the maximum diameter of the transmission gear, and the transmission gear and the inner groove are coaxially arranged. A follower gear plate is positioned above the inner groove. The clamping mechanism also includes equal-angle... A positioning groove is set in the bottom surface of the inner groove, and a corresponding positioning rod extends into the opening end of each positioning groove. A corresponding adjusting block is fixedly connected to the upper end of each positioning rod. A spring sleeved on the outside of the positioning rod is set between the lower surface of the adjusting block and the inner bottom surface of the inner groove. A connecting ring coaxial with the lower surface of the transmission gear is connected to the bearing. Two protrusions are set at equal angles on the lower surface of the connecting ring. The two protrusions are fixedly connected to the upper surfaces of the two adjusting blocks respectively. Each adjusting block is provided with a through groove extending through both sides. One end of a push plate is set in the inner groove, and the other end of the push plate extends movably to the outside of the support base. The push plate has a Y-shaped structure, and its two ends in the inner groove are slidably connected to the two through grooves respectively.

[0009] Preferably, the laser measuring mechanism further includes a limiting tube fixedly connected to the upper surface of the support plate, and a mounting rod is inserted into the upper opening of the limiting tube. The limiting tube and the mounting rod are square structures that fit together. A baffle is fixedly connected to the upper end of the mounting rod. A strip hole is opened on the baffle and extends through both sides. A side plate is fixedly connected to one side of the mounting rod, and a CCD is set on the other side of the mounting rod. A shaft bracket is fixedly connected to the side plate, and a laser is axially connected to the upper end of the shaft bracket. A distance sensor facing the baffle is installed at the lower end of the shaft bracket. The position of the laser corresponds to the position of the strip hole, and the end of the laser facing away from the baffle is axially connected to the upper end of a lifting plate. The lower end of the lifting plate moves through the side plate to below it, and a roller assembly is installed at the lower end of the lifting plate.

[0010] Preferably, the laser measurement mechanism further includes a processing component and a control switch mounted on the upper surface of the base, and the processing component and the control switch, the processing component and the motor, and the processing component and the CCD are all electrically connected.

[0011] Preferably, the laser measuring mechanism further includes a mounting cover disposed on the lower surface of the support plate, and one end of an adjusting knob is connected to a bearing inside the mounting cover. The other end of the adjusting knob is connected to a bearing extending to the outside of the mounting cover, and a worm gear sleeve coaxial with it is fixedly connected to the part of the adjusting knob inside the mounting cover. A screw is movably passed through the support plate, and the outside of the screw is connected to a bearing at the lower end of the support plate. A worm wheel coaxial with it is fixedly connected to the lower end of the screw, and the worm wheel is threadedly connected to the worm gear sleeve. The upper end of the screw is threadedly connected to the lower end of the mounting rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the deformation measuring mechanism for heat treatment of square rails can quickly clamp and release the square rails, and can quickly roll the roller assembly on the surface of the square rails, thereby quickly measuring whether the square rails undergo minute deformation during heat treatment. In addition, when minute deformation of the square rails is detected, the roller assembly will stop moving to facilitate marking by the operator, thus greatly improving the measurement efficiency.

[0013] 1. By pushing the push plate and squeezing the square rail to be tested between the two clamping parts, and then releasing the push plate, the square rail can be stably clamped. This method can quickly clamp square rails of different models. Compared with the method of using a screw to control the movement of the clamping parts, it is more efficient.

[0014] 2. The processing component can read the light path received by the CCD and the distance sensor can read the distance between the laser and the CCD. When the light path changes, the processing component can quickly calculate the deformation of the square rail and stop the motor directly. This allows the operator to mark the location of the deformation. Then, the motor can be restarted by the control switch so that the roller assembly can continue to move on the surface of the square rail and continue the inspection operation. When the roller assembly rolls from one end of the square rail surface to the other end, the deformation detection of the square rail is completed, which is beneficial for the rapid detection of the deformation of the square rail.

[0015] 3. During use, the height of the mounting rod can be adjusted by rotating the adjustment knob, thus enabling the testing of square rails at different heights. Attached Figure Description

[0029] 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.

[0030] Please see Figures 1-10 The present invention provides the following technical solution:

[0031] Example 1: To address the problem that conventional deformation measuring mechanisms for heat-treated square rails cannot quickly clamp the rails, resulting in poor measurement efficiency, the following technical solution is provided: A deformation measuring mechanism for heat-treated square rails includes a base 1 and a support seat 3 supported thereon by a leveling assembly 2. The support seat 3 has a level bubble for observing its tilt. A clamping groove 4 is provided on the support seat 3, and a clamping mechanism is installed within the clamping groove 4. The clamping mechanism includes a roller assembly 30 for clamping the square rail. Two sets of protruding seats 5 are provided on the upper surface of the support seat 3. Furthermore, a lead screw 6 and a limiting shaft 7 are respectively connected to the two sets of protruding seats 5. The lead screw 6 and the limiting shaft 7 are arranged parallel to each other. One end of the lead screw 6 is connected to the bearing of the corresponding protruding seat 5. A motor 8 is also installed on the upper surface of the support base 3, and the output end of the motor 8 is coaxially connected to the other end of the lead screw 6. The bearing of the other end of the lead screw 6 passes through the corresponding protruding seat 5. A support plate 15 is provided above the support base 3, and support frames 14 are fixedly connected to both sides of the lower end of the support plate 15. The two support frames 14 are respectively passed through by the lead screw 6 and the limiting shaft 7, and the lead screw 6 is also threadedly connected to the support frame 14 through which it passes.

[0032] The clamping mechanism also includes a mounting groove 31 opened inside the support base 3 and with openings at both ends within the clamping groove 4. Clamping members 32 are slidably connected to both openings of the mounting groove 31. Roller sets 30 are provided at the ends of each clamping member 32 within the clamping groove 4. The clamping mechanism also includes follower gear plates 33 connected to the ends of the two clamping members 32 extending into the mounting groove 31. A transmission gear 35 meshes with the two follower gear plates 33. The transmission gear 35 is limited and sleeved on the outer side of the lower end of the positioning shaft 42. The upper end of the positioning shaft 42 is connected to the inner top of the mounting groove 31 via a one-way bearing. Magnets are provided on the sides of the clamping member 32 corresponding to the mounting groove 31, and the opposing surfaces of the two magnets have the same magnetic poles. The lower end of the positioning shaft 42 is shaped like a frustum. The upper surface of the transmission gear 35 has a frustum-shaped groove that matches the lower end of the positioning shaft 42. The lower end of the positioning shaft 42 and the frustum-shaped groove on the upper surface of the transmission gear 35 are positioned opposite each other. The transmission gear 35 and the positioning shaft 42 are coaxially arranged. The clamping mechanism also includes an inner groove 34 provided in the mounting groove 31, and the inner groove 34 is open to... The lower end of the positioning shaft 42 is connected to the one-way bearing. The inner diameter of the inner groove 34 is larger than the maximum diameter of the transmission gear 35, and the transmission gear 35 is coaxially arranged with the inner groove 34. The follower gear plate 33 is arranged above the inner groove 34. The clamping mechanism also includes positioning grooves 40 that are equally spaced on the inner bottom surface of the inner groove 34. Each positioning groove 40 has a corresponding positioning rod 39 extending into its open end. Each positioning rod 39 has a corresponding adjusting block 37 fixedly connected to its upper end. A sleeve is provided between the lower surface of the adjusting block 37 and the inner bottom surface of the inner groove 34. The spring 41 on the outside of the rod 39 and the lower surface of the transmission gear 35 are connected to a connecting ring 36 coaxially. The lower surface of the connecting ring 36 is provided with two protrusions at equal angles. The two protrusions are fixedly connected to the upper surfaces of the two adjusting blocks 37 respectively. Each adjusting block 37 is provided with a through groove 38 that runs through both sides. One end of the push plate 13 is provided in the inner groove 34, and the other end of the push plate 13 moves through to the outside of the support base 3. The push plate 13 has a Y-shaped structure, and its two ends in the inner groove 34 are slidably connected to the two through grooves 38 respectively.

[0033] according to Figure 1 and Figures 6-10 Connect the power supply and adjust the support base 3 to a horizontal position through the leveling component 2. The leveling component 2 is a common telescopic structure composed of nut sleeves and bolts.

[0034] Then push the push plate 13, so that the adjusting block 37 moves downward under the action of the inclined through groove 38. During the process, due to the limiting effect of the positioning rod 39 and the positioning groove 40, the adjusting block 37 can be guaranteed to move vertically downward stably. Since the adjusting block 37 is connected to the connecting ring 36, and the connecting ring 36 is connected to the lower surface of the transmission gear 35 by the bearing, the transmission gear 35 will move vertically downward synchronously with the adjusting block 37. After the transmission gear 35 moves downward a certain distance, the lower end of the positioning shaft 42 separates from the frustum-shaped groove on the upper surface of the transmission gear 35. At this time, the two clamping parts 32 can move away from each other or move closer to each other.

[0035] Then, the square rail to be tested is squeezed between the two clamping members 32. Due to the influence of the clamping members 32 and the magnetic sheet on the mounting groove 31, the two clamping members 32 will clamp the square rail to be tested.

[0036] At this time, the push plate 13 is released, and under the action of the spring 41, the transmission gear 35 is reset, which causes the lower end of the positioning shaft 42 to engage with the frustum-shaped groove on the upper surface of the transmission gear 35. At this time, the transmission gear 35 can only move in one direction, which means that the two clamping parts 32 can only move closer to each other, thus limiting the movement of the square rail to be measured.

[0037] In the above process, simply push the plate 13 and squeeze the square rail to be tested between the two clamping parts 32, and then release the push plate 13 to achieve stable clamping of the square rail to be tested.

[0038] Example 2: To solve the problem that the deformation measurement mechanism used in the heat treatment of square rails is not convenient to directly calculate the deformation during measurement, the following technical solution is provided: Specifically, a laser measurement mechanism is installed on the support plate 15, and the laser measurement mechanism includes a CCD 11 for receiving the optical path.

[0039] The laser measuring mechanism also includes a limiting tube 16 fixedly connected to the upper surface of the support plate 15, and a mounting rod 17 is inserted into the upper opening of the limiting tube 16. The limiting tube 16 and the mounting rod 17 are square structures that fit together. A baffle 12 is fixedly connected to the upper end of the mounting rod 17. A strip hole 18 is opened on the baffle 12, penetrating both sides. A side plate 19 is fixedly connected to one side of the mounting rod 17, and a CCD 11 is set on the other side of the mounting rod 17. A shaft bracket 23 is fixedly connected to the side plate 19, and a laser 22 is axially connected to the upper end of the shaft bracket 23. A distance sensor 24 facing the baffle 12 is installed at the lower end of the shaft bracket 23. The position of the laser 22 corresponds to the position of the strip hole 18. The end of the laser 22 facing away from the baffle 12 is axially connected to the upper end of the lifting plate 21. The lower end of the lifting plate 21 moves through the side plate 19 to below it, and a roller assembly is installed at the lower end of the lifting plate 21. The laser measurement mechanism also includes a processing component 9 and a control switch 10 mounted on the upper surface of the base 1. The processing component 9 and the control switch 10, the processing component 9 and the motor 8, and the processing component 9 and the CCD 11 are electrically connected. The laser measurement mechanism also includes a mounting cover 26 disposed on the lower surface of the support plate 15. One end of an adjustment knob 25 is connected to a bearing inside the mounting cover 26. The other end of the adjustment knob 25 is connected to the outside of the mounting cover 26. A worm gear sleeve 27 coaxial with the adjustment knob 25 is fixedly connected to the part of the adjustment knob 25 inside the mounting cover 26. A screw 29 is movably passed through the support plate 15. The outside of the screw 29 is connected to the lower end of the support plate 15 by a bearing. A worm wheel 28 coaxial with the screw 29 is fixedly connected to the lower end of the screw 29. The worm wheel 28 is threadedly connected to the worm gear sleeve 27. The upper end of the screw 29 is threadedly connected to the lower end of the mounting rod 17.

[0040] according to Figures 1-5 During the clamping process after the square rail to be tested is clamped, the lifting plate 21 is first pulled up so that the roller assembly 20 at the lower end of the lifting plate 21 can support the surface of the square rail. The adjustment knob 25 is rotated to drive the worm sleeve 27 to rotate, which in turn causes the worm wheel 28 to drive the screw 29 to rotate. Under the limiting action of the limiting tube 16, the mounting rod 17 moves along the axis of the screw 29, which can adjust the height of the side plate 19 so as to adjust the height of the laser 22.

[0041] When the light path emitted by the laser 22 is horizontal, the processing component 9 issues a reminder. The processing component 9 is equipped with a sound component to remind the staff. The processing component 9 includes a signal receiving module and a signal transmitting module, and the processing component 9 includes a processor for processing information. At this time, the staff can stop rotating the adjustment knob 25.

[0042] Then, the motor 8 is started by the control switch 10. The motor 8 drives the lead screw 6 to rotate, which in turn allows the support frame 14 to move along the axis of the lead screw 6 under the limiting action of the limiting shaft 7, thereby driving the roller assembly 20 to roll on the surface of the square rail.

[0043] When the surface of the square rail is deformed, it generally arches up. During heat treatment, the material expands due to heat, which causes arching. The deformed position will push up the roller assembly 20, which will cause the lifting plate 21 to move upward, thereby driving the laser 22 to deflect. At this time, the light path it generates will no longer be horizontal. After the light path passes through the strip hole 18, it is captured by the CCD 11. Then, its position signal on the CCD 11 is transmitted to the processor in the processing assembly 9. At the same time, the distance sensor 24 will also transmit the distance between the laser 22 and the baffle 12 to the processor. After processing, the processor will directly obtain the deformation.

[0044] At the same time, the processor will also stop motor 8 from running, at which point the staff can mark the deformed position with a marker.

[0045] Then, by controlling switch 10, motor 8 continues to run so that roller assembly 20 continues to roll on the square rail surface so as to detect the next deformation position.

[0046] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
