Description

Technical Field

[0001] This invention belongs to the field of track pad processing, specifically relating to an automatic track pad cutting device based on multiple sensors. Background Technology

[0002] Track pads are sheets made of rubber or plastic. They are placed between the steel rails and concrete rail components to provide insulation and vibration damping. In the production of track pads, large sheets are first produced through high-temperature vulcanization. These large sheets are then cut to obtain the actual track pads. This process requires a cutting device. Existing cutting devices either use a method where the cutting blade moves along the track pad and cuts intermittently, or they use a method where the track pad is directionally transported and cuts intermittently. Regardless of the method used, both the track pad and the cutting blade require external force during processing. When relative movement occurs, uneven force or inaccurate force angle on the cutter or track pad can lead to errors in the timing and angle of the cut, resulting in compromised cutting accuracy. Furthermore, since the track pad is made of highly elastic rubber or plastic, the pressure exerted by the cutter on the track pad and the friction during cutting both act on the blade. There is also a probability that the blade may shift due to uneven force. All of these factors increase the probability of cutting errors. To address these issues, this invention provides an automatic track pad cutting device based on multiple sensors. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic track pad cutting device based on multiple sensors in order to solve the above-mentioned problems.

[0004] The present invention achieves the above objectives through the following technical solutions:

[0005] This invention provides an automatic track pad cutting device based on multiple sensors, including a processing table, a lifting cutting mechanism and a pushing mechanism on the processing table. The pushing mechanism is used to push the track pad to move in a straight line. A distance fixing mechanism is provided on the side of the processing table away from the pushing mechanism. A laser range sensor is provided below the processing table. The laser range sensor, together with the distance fixing mechanism, is used to detect the relative position of the track pad and the lifting cutting mechanism to control the cutting time point. The processing table is also provided with a clamping plate for centering and positioning the track pad.

[0006] The distance-fixing mechanism includes a rotating rod and a positioning plate that works with a laser rangefinder. The rotating rod is equipped with two pressure sensors, and the propulsion mechanism works with the two pressure sensors to detect and adjust the offset of the track pad.

[0007] As a further optimization of the present invention, the processing table has a U-shaped structure. The propulsion mechanism includes a movable plate located inside the processing table and slidably connected to the processing table, a first screw and its driving component below the processing table for controlling the reciprocating translation of the movable plate, a rotatable propulsion frame on the movable plate, the side of the propulsion frame away from the lifting and cutting mechanism being an arc surface with evenly distributed teeth on the arc surface, and an active gear meshing with the teeth on the movable plate.

[0008] As a further optimization of the present invention, a number of crossbars arranged in a linear array are provided between the processing table and the movable plate. The crossbars are slidably connected to the processing table, and adjacent crossbars and the movable plate and an adjacent crossbar are connected by springs.

[0009] As a further optimization of the present invention, the lifting and cutting mechanism includes a frame fixed on the processing table, a lifting frame is provided on the inner side of the frame, a cylinder for driving the lifting frame is provided on the frame, and a number of linearly distributed triangular spikes are provided below the lifting frame. The height of the triangular spikes includes two types, and the high-position triangular spikes and the low-position triangular spikes are interspersed. Any two adjacent triangular spikes overlap in the vertical projection.

[0010] As a further optimization of the present invention, the clamping plates include two clamping plates that are symmetrically distributed from left to right. A rotatable second screw and its driving component are provided on the processing table. The second screw and the driving component are used to control the two clamping plates to move synchronously in opposite directions.

[0011] As a further optimization of the present invention, the rotating rod is connected to the processing table via slide rods at both ends. The processing table has a slide groove corresponding to each slide rod, and a spring for elastically connecting the slide rod is provided in the slide groove. The two ends of the rotating rod are respectively rotatably connected to the slide rod on the same side, and a drive member for controlling the rotating rod is provided on the outside of one slide rod.

[0012] As a further optimization of the present invention, a baffle is provided on the rotating rod, a pressure sensor is embedded in the baffle and the detection surface of the pressure sensor is flush with the outer wall of the baffle, two laser rangefinders are included and the positioning plate corresponds to the laser rangefinders one by one, the positioning plate is fixed below the positioning plate, and the reference line of the two laser rangefinders and the tip of the triangular spike are located in the same vertical plane.

[0013] As a further optimization of the present invention, the slide bar and the processing table are provided with corresponding magnetic blocks.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The automatic track pad cutting device based on multiple sensors can detect whether the track pad is deviated in the transmission direction due to uneven force during the cutting process by the cooperation of two pressure sensors. After the deviation is detected, the track pad can be corrected by the cooperation of the push frame and the drive gear. During the cutting process, the cutting time point can also be confirmed by the cooperation of the laser range sensor and the positioning plate. Through the above positioning and monitoring methods, the cutting accuracy can be effectively improved.

[0016] 2. By using a series of triangular spikes of varying heights instead of traditional cutting blades, and employing point-to-surface contact instead of traditional line-to-surface contact, the difficulty of piercing and cutting the track pad is effectively reduced, the probability of errors during the cutting process is lowered, and cutting accuracy is improved. Furthermore, the staggered arrangement of the triangular spikes allows the cutting area covered by the spikes to form a continuous cutting line, and also allows the spikes to contact the track pad in two batches. Compared to a uniform height distribution, the cutting effect is the same, but the resistance of a single batch of piercing is lower, further reducing the cutting difficulty and improving processing stability.

[0023] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1-4 As shown, the automatic track pad cutting device based on multiple sensors in this embodiment includes a processing table 1. The processing table 1 is equipped with a lifting cutting mechanism and a pushing mechanism. The pushing mechanism is used to push the track pad to move in a straight line. A distance fixing mechanism is provided on the side of the processing table 1 away from the pushing mechanism. A laser rangefinder 17 (ECOTTERLSD-250) is provided below the processing table 1. The laser rangefinder 17, together with the distance fixing mechanism, is used to detect the relative position of the track pad and the lifting cutting mechanism to control the cutting time point. The processing table 1 is also equipped with a clamping plate 7 for centering and positioning the track pad.

[0026] The distance-fixing mechanism includes a rotating rod 12 and a positioning plate 16 that cooperates with the laser rangefinder 17. Two pressure sensors 15 are provided on the rotating rod 12. The propulsion mechanism, in conjunction with the two pressure sensors 15, is used to detect and adjust the offset of the track pad (using the Mingkong Sensing MD-S151 series). A programmable controller (such as the KV Nano series controller) can be used to systematically control the above-mentioned lifting and cutting mechanism, propulsion mechanism, distance-fixing mechanism, laser rangefinder 17, etc.

[0027] The processing table 1 has a U-shaped structure. The propulsion mechanism includes a movable plate 2 located inside the processing table 1 and slidably connected to the processing table 1, a first screw 6 below the processing table 1 for controlling the reciprocating translation of the movable plate 2 and its driving component, a rotatable propulsion frame 3 on the movable plate 2, the side of the propulsion frame 3 away from the lifting and cutting mechanism is an arc surface with evenly distributed teeth on the arc surface, and a drive gear 4 that meshes with the teeth on the movable plate 2.

[0028] A number of horizontal bars 5 arranged in a linear array are provided between the processing table 1 and the movable plate 2. The horizontal bars 5 are slidably connected to the processing table 1, and adjacent horizontal bars 5 and the movable plate 2 are connected by springs.

[0029] The lifting and cutting mechanism includes a stand 10 fixed on the processing table 1. A lifting frame 9 is provided on the inner side of the stand 10. A cylinder for driving the lifting frame 9 is provided on the stand 10. Several triangular spikes 11 arranged linearly are provided below the lifting frame 9 (the sides of the triangular spikes 11 are triangular and the horizontal cross-section is spindle-shaped). The height of the triangular spikes 11 includes two types, and the high-position triangular spikes 11 and the low-position triangular spikes 11 are interspersed. Any two adjacent triangular spikes 11 overlap in the vertical projection.

[0030] The clamping plate 7 includes two clamping plates 7 that are symmetrically distributed from left to right. The processing table 1 is provided with a rotatable second screw 8 and its driving component. The second screw 8 and the driving component are used to control the two clamping plates 7 to move synchronously in opposite directions.

[0031] The rotating rod 12 is connected to the processing table 1 via slide rods 13 at both ends. The processing table 1 has a slide groove corresponding to each slide rod 13, and a spring for elastically connecting the slide rod 13 is provided in the slide groove. The two ends of the rotating rod 12 are rotatably connected to the slide rod 13 on the same side, and a drive component for controlling the rotating rod 12 is provided on the outside of one slide rod 13.

[0032] A baffle 14 is provided on the rotating rod 12. The pressure sensor 15 is embedded in the baffle 14 and the detection surface of the pressure sensor 15 is flush with the outer wall of the baffle 14. There are two laser rangefinders 17 and the positioning plate 16 corresponds to each laser rangefinder 17. The positioning plate 16 is fixed below the positioning plate 16. The reference line of the two laser rangefinders 17 and the tip of the triangular spike 11 are located in the same vertical plane.

[0033] The slide bar 13 and the processing table 1 are equipped with corresponding magnetic blocks 18.

[0034] When using this automatic track pad cutting device, simply place the track pad on the processing table 1. First, the two clamping plates 7 gradually approach each other under the drive of the second screw 8, which can move the track pad to the center of the processing table 1. Then, the motor drives the first screw 6 to rotate, which can drive the entire assembly of the movable plate 2 and the push frame 3 to move. The push frame 3 can continuously push the track pad. The first screw 6 rotates intermittently, and the lifting frame 9 and the triangular spike 11 reciprocate regularly under the action of the cylinder, which can achieve the effect of cutting the track pad at a fixed distance.

[0035] During the process of cutting the track pad at a fixed distance, on the one hand, after the track pad is in contact with the baffle 14 and the pressure sensor 15, the detection data of the pressure sensor 15 can reflect the pressure of the track pad on it. When the detection data of the two pressure sensors 15 are inconsistent, it indicates that the track pad is offset in the direction of movement, resulting in uneven pressure on the pressure end face. At this time, the drive gear 4 is activated. Driven by the drive gear 4, the pusher 3 can drive the track pad that is in contact with it to rotate synchronously until the data of the two pressure sensors 15 are consistent. This corrects the offset of the track pad and avoids cutting errors. On the other hand, the track pad will push the baffle 14, pressure sensor 15, positioning plate 16, rotating rod 12 and sliding rod 13 to move synchronously. The detection data of the laser range sensor 17 is the horizontal distance between the contact surface of the track pad and the baffle 14 and the triangular spike 11. Therefore, the cutting time point is when the detection value of the laser range sensor 17 is consistent with the preset cutting length.

[0036] After a single cut is completed, the motor drives the rotating rod 12 to rotate 90 degrees. The rotating rod 12 and the slide rod 13 slide back to their initial positions under the action of the spring. At the same time, the subsequent track pad resumes feeding and can push down the cut track pad, thus realizing automatic feeding. Then the motor drives the rotating rod 12 to rotate back to the initial position, and the subsequent track pad pushes the baffle 14 again, thus achieving the effect of continuous cutting.

[0037] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
