[0123] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be a more detailed description hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiments

[0124] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the embodiments of the present application as detailed in the appended claims.

[0125] The technical solutions of the embodiments of the present application and how the technical solutions of the embodiments of the present application solve the current problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the embodiments of the present application will be described below with reference to the drawings.

[0126] Please refer to Figures 1 - 4 , the embodiments of the present application provide a crawler plate positioning tooling, including: two or more centering units 1 and a frame unit 2;

[0127] The centering unit 1 is movably connected to the frame unit 2;

[0128] Two of the centering units 1 are arranged opposite to each other to form a centering group;

[0129] The crawler plate is located above the frame unit 2 and between the two centering units 1 of the centering group;

[0130] At least one of the centering units 1 of the centering group moves on the frame unit 2 to position the crawler plate.

[0131] In this example, the centering unit positions the crawler plate, enabling the positioning of crawler plates of different sizes and models without the need to prepare multiple different types of jigs, reducing production costs and avoiding the situation of jig replacement. Therefore, the problems of poor compatibility and adaptability of jig tooling and long jig changeover cycle are eliminated, and the production efficiency of the crawler plate is improved.

[0132] The centering unit positions the crawler plate above the frame unit, facilitating the laser cutting machine to cut the crawler plate positioned in the air and providing convenience for the cutting operation. At the same time, the frame unit can collect the debris generated by cutting the crawler plate, ensuring the cleanliness of the crawler plate cutting environment.

[0133] In a preferred embodiment, the centering unit 1 includes: at least one limit block 11, a support structure 12, a clamping structure 13, a centering support plate 14, and a moving unit 15;

[0134] The limit block 11 is used to contact one end face of the bottom plate of the crawler plate, and the limit blocks 11 of two centering units 1 in a centering group are used to squeeze and fix the crawler plate;

[0135] The support structure 12 is used to contact the lower surface of the crawler plate to support the crawler plate;

[0136] The clamping structure 13 is used to clamp the tooth plate of the crawler plate;

[0137] The limit block 11, the support structure 12, and the clamping structure 13 are respectively fixed on the centering support plate 14;

[0138] The moving unit 15 is connected to the centering support plate 14, the moving unit 15 is fixed on the frame unit 2, and the centering support plate 14 moves on the frame unit 2 through the moving unit 15.

[0139] In this example, the limit block 11 contacts the end face of the bottom plate of the crawler plate. Therefore, the limit blocks 11 of two relatively arranged centering units 1 position the crawler plate in the length direction of the crawler plate.

[0140] The support structure 12 is used to support the crawler plate and contacts the bottom plate and / or the tooth plate of the crawler plate. Therefore, the support structure 12 of the centering unit 1 positions the crawler plate in the thickness direction of the crawler plate.

[0141] The clamping structure 13 is used to clamp the tooth plate of the crawler plate. Therefore, the clamping structure 13 of the centering unit 1 positions the crawler plate in the width direction of the crawler plate. At the same time, since the clamping structure 13 clamps the tooth plate, the axis of the crawler plate is parallel to the axis of the clamping structure 13 of the centering unit 1 arranged oppositely, ensuring the stability and consistency of the positioning posture of the crawler plate.

[0142] Therefore, the centering unit 1 performs centering and positioning on the crawler plate in the length direction, width direction, and thickness direction of the crawler plate, and ensures the stability and consistency of the positioning posture of the crawler plate, ensuring the positioning reliability and firmness of the crawler plate.

[0143] The centering support plate 14 firmly fixes the limit block 11, the support structure 12, and the clamping structure 13.

[0144] The moving unit 15 is used to adjust the position of the centering unit 1, and further adjust the distance between the oppositely arranged centering units 1 to adapt to crawler plates of different lengths. At the same time, the support structure 12 and the clamping structure 13 can adapt to crawler plates of different widths and thicknesses, enabling the centering unit 1 to adapt to the positioning of crawler plates of various models and sizes.

[0145] In a preferred embodiment, the support structure 12 includes: a first support unit 121, a second support unit 122, and a third support unit 123;

[0146] The first support unit 121 is used to support the tooth plate of the double-tooth type crawler plate;

[0147] The second support unit 122 is used to support the bottom plate of the single-tooth type crawler plate and the bottom plate of the triple-tooth type crawler plate;

[0148] The third support unit 123 is used to support the tooth plate of the double-tooth type crawler plate.

[0149] In this example, the first support unit 121 and the third support unit 123 are used to support the two tooth plates of the double-tooth type crawler plate respectively, so that the two tooth plates can be stably placed on the support structure 12.

[0150] The second unit is used to support the bottom plate of the single-tooth type crawler plate and the bottom plate of the triple-tooth type crawler plate, so that the single-tooth type crawler plate and the triple-tooth type crawler plate can be stably placed on the support structure 12.

[0151] Therefore, through the first support unit 121, the second support unit 122, and the third support unit 123, it is possible to adapt to the positioning of support plates with different numbers of teeth, greatly improving the applicable range of the crawler plate.

[0152] In a preferred embodiment, the first support unit 121 has a first support block 1211; the first support block 1211 is used to support the tooth plate of the double-tooth type track shoe;

[0153] The second support unit 122 has a second support block 1221; the second support block 1221 is used to support the bottom plate of the single-tooth type track shoe and the bottom plate of the triple-tooth type track shoe;

[0154] The third support unit 123 has a third support block 1231; the third support block 1231 is used to support the tooth plate of the double-tooth type track shoe;

[0155] The first support block 1211 is located below the clamping structure 13, the moving direction of the first support block 1211 is parallel to the axis direction of the clamping structure 13, and the moving direction of the first support block 1211 is perpendicular to the moving direction of the second support block 1221.

[0156] In this example, the first support block 1211 and the third support block 1231 are used to support the two tooth plates of the double-tooth type track shoe respectively, so that the two tooth plates can be stably placed on the support structure 12.

[0157] The second unit is used to support the bottom plate of the single-tooth type track shoe and the bottom plate of the triple-tooth type track shoe, so that the single-tooth type track shoe and the triple-tooth type track shoe can be stably placed on the support structure 12.

[0158] Therefore, through the first support block 1211, the second support block 1221 and the third support block 1231, the positioning of the support plates with different numbers of teeth can be adapted, greatly improving the applicable range of the track shoes.

[0159] The first support block 1211 is located below the clamping structure 13 to avoid the first support block 1211 affecting the operation of the clamping structure 13 for clamping the tooth plate.

[0160] The moving direction of the first support block 1211 is parallel to the axis direction of the clamping structure 13, so that the first support block 1211 can extend to support the double-tooth type track shoe and retract to avoid the single-tooth type and triple-tooth type track shoes.

[0161] The moving direction of the first support block 1211 is perpendicular to the moving direction of the second support block 1221, so that the extension and retraction of the first support block 1211 and the extension and retraction of the second support block 1221 can adapt to various types of track shoes;

[0162] Exemplarily, since the track shoe of the single-tooth type has only one tooth plate, the first support block 1211 retracts, the second support block 1221 extends, and the second support block 1221 moves to the side close to the clamping structure 13. When the clamping structure 13 clamps the tooth plate of the single-tooth type track shoe, the second support block 1221 can support the bottom plate area near the tooth plate, ensuring the support degree for the track shoe.

[0163] Since the distance between the two tooth plates of the double-tooth type track shoe is relatively wide, the first support block 1211 extends, the second support block 1221 retracts, so that one tooth plate is placed on the first support block 1211, and the other tooth plate is placed on the third support block 1231. The clamping structure 13 clamps one tooth plate to ensure the stability of the double-tooth type track shoe placed on the centering unit 1.

[0164] Since the distance between the three tooth plates of the triple-tooth type track shoe is relatively narrow, the first support block 1211 retracts, and the second support block 1221 retracts, so that one of the tooth plates is clamped by the clamping structure 13, and another tooth plate adjacent to the clamped tooth plate is located on the second support block 1221 to ensure the stability of the triple-tooth type track shoe placed on the centering unit 1.

[0165] Optionally, the second support block 1221 has a card slot 1222, and the tooth plate of the triple-tooth type track shoe is inserted into the card slot 1222 so that the track shoe can be stably placed on the second support unit 122.

[0166] In a preferred embodiment, the centering unit 1 further includes: a first proximity switch 16 and a second proximity switch 17;

[0167] The first proximity switch 16 is fixed on the centering support plate 14; the first proximity switch 16 is used to detect whether the single-tooth type track shoe and the triple-tooth type track shoe reach the loading position; the first proximity switch 16 is located between the clamping structure 13 and the second support unit 122;

[0168] The second proximity switch 17 is fixedly connected to the third support unit 123, and the second proximity switch 17 is used to detect whether the double-tooth type track shoe reaches the loading position.

[0169] In this example, the first proximity switch 16 is used to detect whether there is a track shoe on the second support block 1221. If it is determined that there is a track shoe, the first proximity switch 16 will generate a first clamping signal, and the first clamping signal is used to instruct the clamping structure 13 to clamp the tooth plate of the single-tooth type track shoe and the tooth plate of the triple-tooth type track shoe.

[0170] The second proximity switch 17 is used to detect whether there is a track shoe on the third support block 1231. If it is determined that there is a track shoe, the third proximity switch will generate a second clamping signal, and the second clamping signal is used to instruct the clamping structure 13 to clamp the tooth plate of the double-tooth type track shoe.

[0171] Specifically, the first support unit 121 further includes: a first cylinder 1212, a first connecting plate 1213, at least one first slider 1214, at least one first slide rail 1215, and a first magnetic switch 1216;

[0172] The first cylinder 1212 is fixed on the lower surface of the centering support plate 14;

[0173] The cylinder rod of the first cylinder 1212 is connected to the bottom of the first connecting plate 1213,

[0174] The top of the first connecting plate 1213 is connected to the first support block 1211; the first support block 1211 is used to support the tooth plate of the double-tooth type track shoe;

[0175] The bottom of the first support block 1211 is further connected to the first slider 1214, the first slider 1214 is slidably connected to the first slide rail 1215, and the first slide rail 1215 is fixed on the upper surface of the centering support plate 14;

[0176] The first magnetic switch 1216 is connected to the first cylinder 1212.

[0177] In this embodiment, the first cylinder 1212 drives the first slider 1214 to move on the first slide rail 1215 through the first connecting plate 1213, and the first magnetic switch 1216 is used to control the extension and contraction of the first cylinder 1212.

[0178] Optionally, the centering support plate 14 has a cutout portion, the first connecting plate 1213 is located in the cutout portion, and the first connecting plate 1213 moves in the cutout portion;

[0179] One side of the first support block 1211 has a first support plate, and the first support plate is connected to the first connecting plate 1213.

[0180] In this embodiment, by providing the cutout portion, the first support plate can move in the cutout portion, reducing the weight of the centering support plate 14 and ensuring the unobstructed movement of the first support plate.

[0181] Exemplarily, the first cylinder 1212 is rigidly fixed to the lower surface of the centering support plate 14 by a bolt group, and the axis of its piston rod is perpendicular to the plane of the support plate. It adopts double-acting pneumatic drive and is equipped with a built-in buffer device to reduce movement impact. The cylinder diameter and stroke parameters are designed according to the load requirements of the support block.

[0182] The bottom of the first connecting plate 1213 is connected to the end of the cylinder piston rod through a floating joint, and the top is rigidly connected to the first support block 1211 through screws. It is made of lightweight aluminum alloy material, the surface is anodized, and a reinforcing rib plate is provided in the middle to improve the bending stiffness.

[0183] The first slider 1214 - slide rail mechanism: Two groups of linear slide rails are arranged in parallel on the upper surface of the centering support plate 14, and each slide rail is equipped with two first sliders 1214. The slide rail adopts a Gothic arc groove design, and the slider is built with a four-row steel ball circulation circuit, and the preload level is Z0 (light preload) to ensure the movement accuracy reaches ±0.01 mm.

[0184] The first magnetic switch 1216 is embedded on both sides of the cylinder block of the first cylinder 1212, corresponding to the full retraction and full extension limit positions of the piston rod respectively. It adopts a reed - type proximity sensor, the detection distance ≤ 2 mm, outputs an NPN - type switch signal, and realizes real - time position feedback with the PLC control system.

[0185] A gap of 0.05 - 0.10 mm is reserved between the slider and the slide rail, which can automatically compensate for installation errors and thermal deformation. When the magnetic switch signal is abnormal, the control system triggers an alarm and locks the cylinder action to prevent equipment damage.

[0186] Specifically, the second support unit 122 further includes: a second cylinder 1223, a second connecting plate 1224, at least one second slider 1225, at least one second slide rail 1226, and a second magnetic switch 1227;

[0187] The second cylinder 1223 is fixed on the lower surface of the centering support plate 14;

[0188] The cylinder rod of the second cylinder 1223 is connected to the bottom of the second connecting plate 1224;

[0189] The top of the second connecting plate 1224 passes through the centering support plate 14 and is connected to the second slider 1225;

[0190] The top of the second slider 1225 is connected to the second connecting plate 1224, and the second slider 1225 is also movably connected to the second slide rail 1226;

[0191] The second magnetic switch 1227 is connected to the second cylinder 1223.

[0192] In this embodiment, the second cylinder 1223 drives the second slider 1225 to move on the second slide rail 1226 through the connecting plate, and the second magnetic switch 1227 is used to control the extension and contraction of the second cylinder 1223.

[0193] Exemplarily, the second cylinder 1223 is fixedly mounted on the lower surface of the centering support plate 14 in a flange type, and the axis of the cylinder is vertically arranged with respect to the plane of the support plate. A compound cylinder with a guide shaft is selected, with a built-in double-shaft guide structure to effectively prevent the piston rod from rotating, and the rated thrust is increased by 30% compared with the first cylinder 1212 to meet higher load requirements.

[0194] The second connecting plate 1224 adopts a "T"-shaped double-layer plate structure. The lower layer plate is connected to the cylinder rod, and the upper layer plate extends through the rectangular guide hole opened on the support plate. The bottom is connected to the cylinder rod through an elastic coupling to compensate for the installation coaxiality error.
