Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle manufacturing, in particular to a hoisting device and a vehicle. BACKGROUND

[0002] The white body refers to the body after welding and before painting. For the white body welding production line, due to the different transmission forms between the line bodies of the current welding production lines, both multi-model inline production and effective and reasonable use of the site space need to be completed. Under the limitation of the limited site layout conditions, the part shape size, the production line body beat, etc., it is necessary to develop towards the production mode of automation, high flexibility, few people and intelligence. The assembly transmission form between different line bodies and the influence of the preceding and subsequent line bodies on the production line start rate during the fault stop process determine the automation and intelligence degree of the whole welding production line. The high-flexibility and automatic production line has become the planning layout trend.

[0003] The APC (Automatic Pallet Change) accumulation chain technology is widely used on the flexible line body, which can realize the transmission of parts between different line bodies. The APC accumulation chain is often used in the automatic feeding scene after the parts are placed at the feeding port, and can realize the multi-piece placement of multiple parts and multiple varieties. This feeding form often adopts the transmission mode of fixed APC on the ground. At the same time, for the transmission between different line bodies, such as the interface and splicing form of the front wall assembly to the floor, the side wall assembly to the main welding, etc., APC accumulation chain is often used to complete. Because the transmission process between different line bodies is often in the form of cross-region, cross-channel, cross-station, two-layer platform transfer, etc., it is often realized by air APC accumulation chain transmission. After the part assembly produced by the preceding line body is welded, the robot carrying gripper places it on the tray of the air APC accumulation chain, and then transmits it to the feeding port of the subsequent line body across the region and line body, to complete the transportation function of multiple parts of multiple varieties. The number of trays on the APC accumulation chain can be determined according to the length of the transmission distance to realize the part storage function, reduce the influence of the beat caused by the line body stop due to the fault between different regional line bodies, and reduce the influence on the production line availability.

[0004] However, the existing tray structure of the APC accumulation chain is prone to cause the shaking of the parts when moving the parts, which affects the stability of the transmission and is not conducive to realizing reliable part transmission. In addition, the shaking of the parts also causes the collision and damage of the parts, etc. After the parts are transmitted to the preset position, the stability of the parts is insufficient, which is not conducive to the robot of the next station to grab the parts, and further affects the part transmission efficiency.

[0057] As Figures 1-5As shown, the hoisting device (hereinafter referred to as "device") provided by the present application is used to hoist the parts 100 from the first station to the second station. The device comprises a transmission mechanism 1, a plurality of tray mechanisms 2 and a to-position clamping mechanism 3, both ends of the transmission mechanism 1 are located above the first station and the second station respectively; a plurality of tray mechanisms 2 are horizontally and spacedly connected to the transmission mechanism 1, the tray mechanism 2 comprises a base plate 21, an X-direction limiting piece 22, a Y-direction limiting piece 23 and a Z-direction limiting piece 24, one side of the base plate 21 is connected to the transmission mechanism 1 so as to be movable under the driving of the transmission mechanism 1, the other side of the base plate 21 is connected to the X-direction limiting piece 22, the Y-direction limiting piece 23 and the Z-direction limiting piece 24, the Z-direction limiting piece 24 hooks the part 100 so as to move the part 100 from the first station to the second station, the X-direction limiting piece 22 can abut against the part 100 so as to limit the shaking of the part 100 along the moving direction, the Y-direction limiting piece 23 clamps the part 100 so as to limit the shaking of the part 100 in the horizontal plane perpendicular to the moving direction; the to-position clamping mechanism 3 is arranged below the end of the transmission mechanism 1 close to the second station and can clamp the part 100.

[0058] The device provides the power to move the part 100 from the first station to the second station through the transmission mechanism 1. Specifically, the transmission mechanism 1 is driven by a SEW motor to realize cross-channel transmission; the transmission mechanism 1 comprises a transmission chain, the length of the transmission chain is 8660mm, the transmission speed is 8.3mm / min, and the repeat positioning accuracy is ±0.5mm. Preferably, the transmission mechanism 1 can select APC accumulation chain or other structures that can play the function of conveying, and since there are existing structures, the specific structure will not be described in detail here. The lower side of the transmission mechanism 1 is provided with a plurality of tray mechanisms 2, and the plurality of tray mechanisms 2 are horizontally and spacedly arranged so that each tray mechanism 2 can correspondingly bear one part 100, realize batch transmission of the parts 100, increase the number of part 100 buffer, and improve the efficiency and automation degree. Specifically, the transmission chain can drive 12 groups of tray mechanisms 2 to make linear and overturning motion, and the spacing between adjacent tray mechanisms 2 can be 600mm to provide the storage capacity of the parts 100, and the transmission chain can provide 19min of part 100 buffer for coping with line fault stoppage, reducing the reduction of the availability rate caused by the production line fault stoppage, and further causing the influence on the production efficiency; a buffer damping mechanism can be arranged between different tray mechanisms 2 to ensure the stable operation of the tray mechanism 2 and reduce the risk of collision of the parts 100. Preferably, the size of the tray mechanism 2 can be 1115mm×955mm×466mm.

[0059] Specifically, the tray mechanism 2 is connected to the conveying mechanism 1 through one side of the base plate 21, realizing the connection of the tray mechanism 2 and the conveying mechanism 1; the other side of the base plate 21 is provided with an X-direction limiting piece 22, a Y-direction limiting piece 23 and a Z-direction limiting piece 24. Among them, the Z-direction limiting piece 24 is used to hook the part 100, so as to be able to hoist the part 100, thereby realizing the limiting of the part 100 in the vertical direction. Further, the Z-direction limiting piece 24 can include a hooking plane or a hooking groove and the like structure to realize the purpose of reliably hooking the part 100. After hooking the part 100 through the Z-direction limiting piece 24, the part 100 is spaced apart from the ground at this time, and the conveying mechanism 1 can drive the part 100 to move, in order to improve the stability of the part 100 in the transmission process, the X-direction limiting piece 22 and the Y-direction limiting piece 23 are also provided on the lower side of the base plate 21. In the embodiment, the part 100 includes an abutting surface perpendicular to the moving direction and a limiting structure for clamping, and the limiting structure can be a limiting hole or a limiting groove; preferably, the part 100 is a front wall assembly part. The X-direction limiting piece 22 abuts against the abutting surface of the part 100, so as to reduce the shaking of the part 100 along the moving direction; the Y-direction limiting piece 23 clamps the limiting mechanism of the part 100 or clamps both ends of the part 100 perpendicular to the moving direction, thereby reducing the shaking of the part 100 in the horizontal plane along the direction perpendicular to the moving direction. It can also be said that taking the moving direction of the part 100 as the front side, and vice versa as the rear side, and taking the horizontal plane perpendicular to the moving direction as left and right, the tray mechanism 2 can realize the limiting in the vertical direction through the Z-direction limiting piece 24, realize the limiting in the front-rear direction through the X-direction limiting piece 22, and realize the limiting of the part 100 in the left-right direction through the Y-direction limiting piece 23, thereby realizing the stable transmission of the part 100 in the hoisting process, and relieving the collision damage caused by the shaking of the adjacent part 100. The device is also provided with a to-position clamping mechanism 3, which is arranged below the conveying mechanism 1 close to the second station, and is used to stabilize the transmitted part 100, further reducing the shaking of the part 100 when entering the next station, thereby relieving the problem of difficult to grasp after the part 100 is in position, and further improving the production efficiency.

[0060] Preferably, the flatness requirement of the base plate 21 is 0.02 / 1000mm, and the maximum is not more than 0.1mm; the thickness of the base plate 21 is preferably 15mm; the skirt edge of the base plate 21 is sprayed with yellow paint, and the assembly surface is sprayed with golden yellow varnish, so as to facilitate identification during assembly.

[0061] Optionally, the device further comprises a read-write mechanism 4, which is arranged at one end of the conveying mechanism 1 close to the first station and the second station, and can identify the part 100 on the to-position clamping mechanism 3.

[0062] The read-write mechanism 4 comprises an FRID read-write system, and the part 100 can be provided with an identification tag, and the FRID read-write system is used for writing or reading the identification tag to obtain the part 100 information, so as to ensure the transmission position correctness of different parts 100 and ensure the reliable operation of vehicle assembly. Specifically, the read-write mechanism 4 can be arranged at positions close to the first station and the second station of the transmission mechanism 1, so as to write the vehicle model information at the first station and read the vehicle model information at the second station, accurately identify the information of the part 100 entering or outputting the device, and facilitate the inspection of the transmission of the part 100 through the arrangement of the read-write mechanisms 4 at both ends.

[0063] As shown in Figures 1-6 Optionally, the base plate 21 comprises a first connecting part 211 and a second connecting part 212, the first connecting part 211 is connected to the transmission mechanism 1, and the two ends of the second connecting part 212 are arranged at a preset angle with the two ends of the first connecting part 211, and the Y-direction limiting part 23 and the Z-direction limiting part 24 are connected to the second connecting part 212, so that the included angle between the width direction of the part 100 and the moving direction is less than 90°.

[0064] The first connecting part 211 and the second connecting part 212 can be integrally formed, and the extension directions of the two ends of the second connecting part 212 are arranged at a preset angle with the extension direction of the first connecting part 211. After assembly, due to the arrangement of the second connecting part 212, the included angle between the abutting surface of the part 100 after hooking and the moving direction is less than 90°, so that the influence of factors such as wind resistance can be reduced during movement, which not only helps to ensure the moving speed, but also reduces the risk of shaking, bumping and falling caused by excessive wind resistance.

[0065] Optionally, a plurality of weight-reducing holes 213 are arranged on the base plate 21.

[0066] Since the transmission mechanism 1 needs to drive the tray mechanism 2 to move, the weight-reducing holes 213 are arranged on the tray mechanism 2 to reduce the load. Specifically, the position where the first connecting part 211 and the second connecting part 212 need to be connected is an entity structure, and a plurality of weight-reducing holes 213 can be arranged on the premise of ensuring sufficient strength, so that the base plate 21 is in a frame structure.

[0067] Optionally, the tray mechanism 2 further comprises a plurality of connecting parts 25 connected to each other, and the Y-direction limiting part 23 and the Z-direction limiting part 24 are arranged at a plurality of positions, and the Y-direction limiting part 23 and the Z-direction limiting part 24 are connected to the two ends of the second connecting part 212 through the plurality of connecting parts 25, and the connecting part 25 is in an L shape.

[0068] The two ends of the second connecting part 212 can be symmetrically provided with Y-direction limit members 23 and Z-direction limit members 24, or the positions of the Y-direction limit members 23 and the Z-direction limit members 24 and the relative positions of the Y-direction limit members 23 and the Z-direction limit members 24 at the two ends of the second connecting part 212 can be different according to the structure of the part 100, as long as the part 100 can be hooked and limited. The Y-direction limit members 23 and the Z-direction limit members 24 can be connected to the end of the second connecting part 212 through a plurality of connecting members 25. Further, the positions of the Y-direction limit members 23 and the Z-direction limit members 24 relative to the base plate 21 can be preliminarily determined by the connection positions between different connecting members 25 and the number of the connecting members 25. The L-shaped connecting members 25 not only facilitate the adjustment of the spatial positions of the Y-direction limit members 23 or the Z-direction limit members 24 by connecting different surfaces, but also facilitate the provision of a larger connection surface to ensure the reliability of the connection. Preferably, the connecting members 25 can be positioned by pins and connected by bolts or screws when connected, such as a structure connected by two pins and two bolts.

[0069] Optionally, the Z-direction limit members 24 are at least two, and the two Z-direction limit members 24 are respectively arranged at the two ends of the second connecting part 212. The Y-direction limit members 23 are at least four, so that the two sides of the Z-direction limit members 24 are each provided with a Y-direction limit member 23.

[0070] Since the Z-direction limit members 24 are used to hook the part 100 and are the main structure for lifting the part 100, although a single Z-direction limit member 24 can achieve the purpose of hooking, it is subjected to a large stress and is not easy to ensure stability. While the device reliably hooks the part 100 by providing two Z-direction limit members 24, it is considered that the part 100 is easily moved left and right on the Z-direction limit members 24 in a direction perpendicular to the moving direction. Therefore, the Y-direction limit members 23 are arranged on both sides of each Z-direction limit member 24, so as to achieve the left and right limiting effect of the hooking position of each part 100 and avoid left and right shaking. It can be understood that the number of Z-direction limit members 24 and Y-direction limit members 23 and the relative positions of the two can be determined according to the actual situation. Specifically, the Z-direction limit members 24 can be trapezoidal block structures to ensure sufficient strength. The Y-direction limit members 23 are pin-shaped structures, so as to be easily inserted into the limiting structure of the part 100 or clamped to the left and right ends of the part 100. The Z-direction limit members 24 and the Y-direction limit members 23 are provided with connecting members 25 on the rear side in the moving direction, so that when the part 100 is moved, the part 100 is abutted against the connecting members 25 due to the inertial effect, thereby avoiding the part 100 from slipping due to the inertial effect. A clamping structure can also be provided on the Z-direction limit members 24 and / or the Y-direction limit members 23 to avoid accidental slipping when the part 100 is moved. The clamping structure can be a clamping block, a clamping groove or the like.

[0071] Optionally, the tray mechanism 2 further comprises a support seat 26, the X-direction limiting member 22 is connected to the lower side of the base plate 21 through the support seat 26, and the X-direction limiting member 22 is provided with at least two, and the two X-direction limiting members 22 are symmetrically arranged along the length direction of the second connecting part 212.

[0072] The support seat 26 can comprise a support horizontal rod 261 and a support vertical rod 262, one end of the support vertical rod 262 is connected to the base plate 21, and the other end is connected to the support horizontal rod 261, and through the rod-shaped structure, the connecting support effect can be realized while the volume is reduced and the weight is lightened. The support seat 26 can be fastened and connected to the base plate 21 through four M10 bolts; one end of the support vertical rod 262 can be provided with a connecting block or a connecting surface to increase the connecting area with the base plate 21; the other end of the support vertical rod 262 is connected to the middle part of the support horizontal rod 261, so that the two X-direction limiting members 22 arranged on the support horizontal rod 261 can be symmetrically arranged on both sides of the straight line where the center of the base plate 21 is located, that is, symmetrically arranged along the length direction of the second connecting part 212, so as to reliably abut against the abutting surface of the part 100, limit the X-direction shaking, prevent the part 100 from being knocked and overturned, and ensure the force balance. The support seat 26 is sharp and deburred, and the surface is blackened to avoid scratching the part 100; the X-direction limiting member 22 is a nylon block structure to prevent the part 100 from being scratched.

[0073] Optionally, the tray mechanism 2 further comprises a gasket 27, and the connecting end surface of the connecting member 25 and the connecting end surface of the support seat 26 are each provided with a plurality of gaskets 27, so as to adjust the support positions of the X-direction limiting member 22, the Y-direction limiting member 23 and the Z-direction limiting member 24 by increasing or decreasing the number of gaskets 27.

[0074] After the X-direction limiting member 22, the Y-direction limiting member 23 and the Z-direction limiting member 24 are preliminarily limited through the connection of different connecting members 25, the number of gaskets 27 can be increased or decreased to realize the accurate adjustment of the X-direction limiting member 22, the Y-direction limiting member 23 and the Z-direction limiting member 24 in the X-direction, the Y-direction and the Z-direction respectively according to the structure of the part 100, so as to fix the position of the part 100 relative to the tray mechanism 2 through accurate limiting, so as to reliably realize the accurate positioning of the part 100 in the air and limit the shaking of the part 100. For example, the number of gaskets 27 can be adjusted to adjust the position of the X-direction limiting member 22 along the moving direction. Specifically, the thickness of the gasket 27 can be 3mm of bidirectional adjustment gasket. The structures of the tray mechanism 2 can be fixed through the two pin members positioning and two screw fixing modes, quenched to make the surface hardness greater than or equal to HRC50, and blackened to prevent rusting.

[0075] As Figures 1-12As shown, optionally, the in-position clamping mechanism 3 is provided with at least two, which are symmetrically arranged on both sides of the moving direction, and comprises a base 31, a clamping assembly 32 and a supporting assembly 33. The base 31 is arranged on the bottom surface at one end, and the supporting assembly 33 and the clamping assembly 32 are connected to the other end of the base 31. The supporting assembly 33 cooperates with the clamping assembly 32 to clamp the part 100.

[0076] As shown, Figure 7 The two in-position clamping mechanisms 3 can clamp the left and right ends of the part 100 respectively, so that the part 100 is stable at the second station. The in-position clamping mechanism 3 is placed on the ground through the base 31, so that the clamping assembly 32 and the supporting assembly 33 are arranged spaced apart from the ground, thereby facilitating the realization of the front and rear surfaces of the part 100. Specifically, the clamping assembly 32 and the supporting assembly 33 can move towards each other to clamp or move away from each other to the initial state of unfolding, so as to clamp when the part 100 moves above the in-position clamping mechanism 3, and avoid interference when transmitting to the next station to affect the movement of the part 100.

[0077] As shown, Figures 8-12 Optionally, the base 31 comprises two foot supports 311 and a connecting plate 312, and the two ends of the connecting plate 312 are connected to the two foot supports 311 respectively.

[0078] The two foot supports 311 are arranged spaced apart in a direction perpendicular to the moving direction, and the top portions of the two foot supports 311 are connected through the connecting plate 312, so that the supporting assembly 33 and the clamping assembly 32 can be arranged on the connecting plate 312. Specifically, the foot support 311 is integrally cut by wire, without the need for welding structure, thereby enhancing the supporting strength.

[0079] Optionally, the clamping assembly 32 comprises a first swing cylinder 321 and a first clamping jaw 322, and the fixed part of the first swing cylinder 321 is connected to the base 31, and the first clamping jaw 322 is connected to the rotating part of the first swing cylinder 321. The supporting assembly 33 comprises a second swing cylinder 331 and a second clamping jaw 332, and the fixed part of the second swing cylinder 331 is connected to the base 31, and the second clamping jaw 332 is connected to the rotating part of the second swing cylinder 331.

[0080] The first clamping jaw 322 and the second clamping jaw 332 can be connected by a plurality of connecting units, and the shape and size of the connecting units are not specifically limited, and the clamping can be achieved according to the shape of the part 100. When clamping, the first clamping jaw 322 is driven to rotate by the rotating part of the first swing cylinder 321, so that the end of the first clamping jaw 322 away from the first swing cylinder 321 is flipped to above the base 31; similarly, the action of the second clamping jaw 332 is similar to that of the first clamping jaw 322, so that the end of the first clamping jaw 322 away from the first swing cylinder 321 and the end of the second clamping jaw 332 away from the second swing cylinder 331 achieve clamping. Further, through the shape and size of the connecting units, the connecting units can also achieve the clamping action on the part 100, so that the first clamping jaw 322 and the second clamping jaw 332 together achieve the clamping action on the part 100. Preferably, when the connecting units of the first clamping jaw 322 and the second clamping jaw 332 are connected, a plurality of gasket structures can be arranged at the connecting position, so that the spatial position of the first clamping jaw 322 and the second clamping jaw 332 can be accurately adjusted by increasing or decreasing the gasket structures, and the clamping of the part 100 can be better achieved.

[0081] Optionally, one end of the first clamping jaw 322 is connected to the first swing cylinder 321, one end of the second clamping jaw 332 is connected to the second swing cylinder 331, the other end of the first clamping jaw 322 and the other end of the second clamping jaw 332 can abut to generate a clamping force to clamp the part 100, and the first clamping jaw 322 and the second clamping jaw 332 are each provided with a first limiting piece 34, and the base 31 is correspondingly provided with a second limiting piece 313, the first limiting piece 34 can be positioned and matched with the second limiting piece 313 to limit the clamping force.

[0082] Preferably, one of the first limiting piece 34 and the second limiting piece 313 includes a block structure, and the other includes a groove structure, the block structure and the groove structure are matched to prevent the first clamping jaw 322 and the second clamping jaw 332 from continuing to clamp after clamping to a certain extent, thereby avoiding damage to the part 100 due to excessive clamping force between the first clamping jaw 322 and the second clamping jaw 332. Further, one of the block structure and the groove structure can be provided with a protruding part, and the other can be provided with an inner recess, so that accurate positioning and matching can be further achieved by the cooperation of the protruding part and the inner recess. The shape, size and arrangement position of the first limiting piece 34 can be matched with the second limiting piece 313. Specifically, the structures of the clamping mechanism 3 can be positioned by pin structures, connected by bolts or screws for easy disassembly, and gasket structures can be arranged at the connecting position or the matching position to accurately adjust the position and accurately match the position. Through the arrangement of the gasket 27 and the connecting piece 25 of the tray mechanism 2, and the arrangement of the connecting units and the gasket structures of the clamping mechanism 3, the adjustability of the device is better, and the device can be applied to parts 100 of various vehicle models.

[0083] Optionally, the first swing cylinder 321 and the second swing cylinder 331 are connected to the lower side of the connecting plate 312, and the first swing cylinder 321 and the second swing cylinder 331 are arranged in parallel and reversely to reduce the length of the in-place clamping mechanism 3 along the moving direction.

[0084] The first swing cylinder 321 and the second swing cylinder 331 are connected to the connecting plate 312 at the middle part, which avoids the length of the in-place clamping mechanism 3 along the moving direction being too long due to the fixed part being far away from the rotating part, and is not conducive to reducing the space occupation. In the embodiment, under the premise of ensuring that the rotating part is not interfered, the parallel and reverse arrangement of the first swing cylinder 321 and the second swing cylinder 331 helps to arrange the in-place clamping mechanism 3 in a factory with small space. Moreover, since the supporting assembly 33 and the clamping assembly 32 are used for clamping cooperation, the tray mechanism 2 is used for driving and limiting the parts 100, the device can be applied to parts 100 of various vehicle models, the applicability is improved, and the investment and reconstruction cost caused by the introduction of vehicle models is reduced.

[0085] Optionally, the in-place clamping mechanism 3 further comprises a sensor 35, and the sensor 35 is arranged on the first clamping jaw 322 or the second clamping jaw 332 to detect the position and / or type of the part 100 after clamping.

[0086] The sensor 35 can be arranged at a preset position on the in-place clamping mechanism 3, and can achieve the purpose of detecting the part 100. Preferably, the sensor 35 comprises an in-place detection sensor and a part identification sensor. Since the device comprises at least two in-place clamping mechanisms 3 cooperating with each other, the in-place detection sensor can be arranged on the second clamping jaw 332 of one of the supporting assemblies 33, and the part identification sensor can be arranged on the second clamping jaw 332 of the other supporting assembly 33, so as to detect whether the part 100 reaches the preset position through the in-place detection sensor, and detect the shape difference such as width of the part 100 through the part identification sensor to determine the type information of the part 100. The part identification sensor and the read-write mechanism 4 can cooperate with each other to realize the information identification of the part 100, so as to ensure accurate identification of the type of the part 100, avoid the part 100 from being unable to be transmitted to the corresponding station due to identification error, and affect the production efficiency.

[0087] The device is also equipped with necessary control mechanisms, including a line body PLC, to control the actions and uses of the transmission mechanism 1, the read-write mechanism 4, the sensor 35, and the like through a program, to ensure that the device can be smoothly transmitted and accurately positioned. The operator needs to regularly perform PM (Preventive Maintenance and Productive Maintenance) and TPM (Total Productive Maintenance) to check the wear of the Y-direction limiting piece 23 and the Z-direction limiting piece 24, and the like, wherein the maximum wear of the Y-direction limiting piece 23 is not more than 0.2 mm, and the maximum wear of the Z-direction limiting piece 24 is not more than 0.5 mm. If the detection is unqualified, it needs to be replaced in time to avoid the problem of inaccurate spatial positioning of the part 100 due to the decrease in limiting accuracy, which in turn leads to the problem of being unable to reliably grasp the part 100.

[0088] In use, the part 100 can be hooked onto the tray mechanism 2 at the first station by the pre-robot gripper, and the vehicle model information can be written into the identification tag by the read-write mechanism 4. After the hooking and positioning are completed, the gripper is withdrawn, and the part 100 is transmitted to the second station by the transmission mechanism 1. After the part 100 reaches the second station, the part 100 is flipped and clamped by the clamping assembly 32 and the supporting assembly 33 of the in-place clamping mechanism 4, to realize the fixation of the part 100. The sensor 35 detects the part 100, feeds back the in-place information of the corresponding part 100 to the PLC, and transmits the vehicle model information read by the RFID to the next line PLC, to realize the comparison with the next production line. After the comparison is successful, the part 100 is grasped by the robot gripper, the tray mechanism 2 is flipped by the transmission chain and transmitted to the first station, to complete the transmission of the part 100 in one process.

[0089] The embodiment also provides a vehicle including the part 100, which is hoisted by the hoisting device described above, so that the part 100 is moved from the first station to the second station, to facilitate the assembly to form the vehicle.

[0090] The vehicle can be a truck, and the hoisting device adopts a single-layer hoisting form to reduce the ground space occupation. At the same time, the space occupation of the in-place clamping mechanism 3 arranged on the ground is small, so that the device can be applied to the situation of narrow space and height limitation of the truck factory welding production line, as well as the setting position of the factory column and water pipe, to effectively and reasonably utilize the space while improving the production efficiency.

Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the scope of the present application. It is not necessary or possible to enumerate all the embodiments.
