During the assembly process, a gantry lift is generally used to lift the frame, and then lower the frame to the body below during assembly.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] It should be understood that for this application:

[0042] Large military vehicles or off-road vehicles with beams are large in size and high in height. The gantry lift is limited by the upper crossbeam assembly and has a total lifting height of 3.5 meters and an upper limit of 2 meters. Large military vehicles or off-road vehicles with beams are nearly 2 meters high, so the gantry lift cannot lift the frame to the top of the body and is not applicable.

[0043] In addition, after the assembly is completed, it needs to be transferred. Using an overhead crane to move it will bring risks of high-altitude operations, making it difficult to ensure work efficiency and personnel safety.

[0044] In some related technologies, a transfer trolley is used for transfer equipment, which does not require an overhead crane and does not have the height limitation defect of a gantry lift. However, the current transfer trolley can only realize transfer and lifting operations, but it is difficult to participate in the process of assembling the frame and the body. There are the following difficulties:

[0045] In general, when the frame and the body are assembled, the frame is placed on a support frame, such as a frame saddle 10, the top of the frame saddle 10 is used to place the frame structure b, and the bottom has two legs. When the traditional transfer trolley is used to lift the body structure a, it is impossible to directly place the transfer trolley under the frame saddle 10 along the length direction of the body structure a, and the body structure a is located above the frame structure b. This is due to the structure of the transfer trolley. For example, the assembly method of the full-load-bearing passenger car powertrain disclosed in the Chinese application CN 106672853A adopts a self-propelled and mechanized lifting method, and the full-load-bearing passenger car powertrain is placed on an assembly trolley platform driven by a motor, and the full-load-bearing passenger car powertrain is transported to the bottom of the frame by a self-propelled device, and then the full-load-bearing passenger car powertrain is lifted to a suitable position by a hydraulic lifting mechanism, and is precisely adjusted by a hydraulically controlled lateral adjustment mechanism and a floating adjustment mechanism, so that the full-load-bearing passenger car powertrain is accurately connected and installed on the frame. Its hydraulic lifting mechanism will interfere with the frame saddle 10 and the frame structure b and cannot move.

[0046] The frame structure b is generally placed on the frame saddle 10 with the front lower and the back higher. Generally, the transfer trolley is lowered or lifted as a whole, and cannot be lifted and lowered separately at a fixed point or position. Therefore, it does not conform to the actual frame and body assembly operation process.

[0047] On the first aspect, the embodiments of the present application provide an auxiliary frame and body assembly device to solve the problem in the related art that the gantry lift is limited in lifting height by the upper crossbeam assembly and is difficult to adapt to large military vehicles or off-road vehicles with large beams.

[0048] Please refer to Figure 1-Figure 4 , an auxiliary frame and vehicle body assembly device, comprising:

[0049] A vehicle body support plate 1, the bottom of which is provided with a movable roller 2;

[0050] A plurality of transverse telescopic components 3 are divided into two groups, and the two groups of transverse telescopic components 3 are distributed on both sides of the body support plate 1 in the width direction; a frame horse stool avoidance groove 5 extending along the length direction of the body support plate 1 is provided on the body support plate 1 and between the two groups of transverse telescopic components 3; each transverse telescopic component 3 is connected to a support 12 to drive the support 12 to move in the width direction;

[0051] A plurality of vertical telescopic components 4 are arranged in one-to-one correspondence with the horizontal telescopic components 3 and are connected via a support 12 .

[0052] When in use, the vehicle body structure is directly placed on the top of the vertical telescopic component 4, and then the vehicle body pallet 1 is moved to make the vehicle body structure a and the frame structure b collinear in the length direction of the vehicle; then the lateral telescopic component 3 and the vertical telescopic component 4 are adjusted to form a height of the vehicle body structure a greater than the height of the frame structure b, and a space is formed for the frame saddle 10 and the frame structure b to pass through, and then the vehicle body pallet 1 is directly pushed under the frame saddle 10, and the frame saddle avoidance groove 5 is used to avoid the frame saddle 10, and then the vehicle body structure a is dropped to complete the assembly. Through the use of this device, there is no need to use a gantry lift, and there is no defect of height limit. At the same time, the vehicle body structure a is transferred to the top of the frame structure b during the whole process, and the separated vehicle body pallet 1 is located under the frame saddle 10. The lifting and separation process does not require the use of hoisting, which has a high safety factor.

[0053] After the above assembly is completed, the auxiliary frame and the body assembly equipment can be directly taken out along the colinear direction, thereby realizing the lifting of the body structure a, the lowering of the body structure a, the separation of the body support plate 1 and the body structure a, and the body support plate 1 is located under the frame saddle 10 without interfering with the bottom of the frame saddle 10.

[0054] That is, the original vehicle body structure a and the vehicle body pallet 1 are transferred as a whole. After the transfer is in place, the vehicle body structure a is lifted and separated from the vehicle body pallet 1. When falling, from top to bottom, they are the vehicle body structure a, the frame structure b, the frame saddle 10 and the vehicle body pallet 1, which can be regarded as a whole of the vehicle body structure a and the vehicle body pallet 1, and are deformed in an intersecting position with the frame saddle 10 and the frame structure b.

[0055] In some preferred embodiments, reference Figure 1 and Figure 2 Since the movement process of the vehicle body structure a needs to be stable and cannot have a large shaking, the connection structure of the specific lateral telescopic component 3 and the vertical telescopic component 4 is described in detail below:

[0056] For the horizontal telescopic component 3;

[0057] A support guide groove 6 parallel to the width direction is provided on the vehicle body pallet 1; a guide block movably connected to the support guide groove 6 is provided at the bottom of the support 12; the transverse telescopic assembly 3 includes a first hydraulic telescopic cylinder and a first controller connected to each other, and the first hydraulic telescopic cylinder is parallel to the width direction; the output end of the first hydraulic telescopic cylinder is connected to the support 12.

[0058] The first hydraulic telescopic cylinder is a self-locking hydraulic cylinder, and the support guide groove 6 and the guide block are used in coordination to achieve precise guidance. In addition, there are four transverse telescopic components 3. Since the frame horse stool avoidance groove 5 is located between the two sets of transverse telescopic components 3, the first hydraulic telescopic cylinder can move in the width direction of the vehicle body support plate 1 at four points, and will not interfere with the frame horse stool 10 and the frame structure b after adjustment.

[0059] Furthermore, the support 12 includes a base plate 120, a mounting block 121 is provided in the middle of the base plate 120; the cross-sectional area of ​​the mounting block 121 gradually decreases from the bottom of the mounting block 121 toward the top of the mounting block 121; the base plate 120 has extensions on both sides in the length direction. The setting of the support 12 can increase the contact area with the top surface of the vehicle body support plate 1, increase the force point, thereby avoiding shaking during movement and improving the overall structural strength.

[0060] For the vertical telescopic component 4;

[0061] The vertical telescopic assembly 4 includes a second hydraulic telescopic cylinder and a second controller connected to each other, and the second hydraulic telescopic cylinder is arranged vertically; the bottom of the second hydraulic telescopic cylinder is provided with a diagonal support rod connected to the base plate 120. The support of the diagonal support rod improves the connection strength and avoids damage caused by stress concentration in the connection. The second hydraulic telescopic cylinder is a self-locking hydraulic oil cylinder; the second controller and the first controller can be integrated together for easy control. As described above, in this embodiment, no further introduction is made to the hydraulic oil circuit structure for controlling the second hydraulic telescopic cylinder and the first hydraulic telescopic cylinder, because this is a relatively mature solution.

[0062] The number of the second hydraulic telescopic cylinders is also four, corresponding to the first hydraulic telescopic cylinder, which can realize lifting of the vehicle body structure a, and also realize contact with the reinforced sheet metal at the longitudinal bottom longitudinal beam of the vehicle body structure a to realize stable lifting. In addition, since the frame structure b is generally placed on the frame saddle 10 in a state of low front and high rear, the above second hydraulic telescopic cylinder and the first hydraulic telescopic cylinder form an overall structure of transverse movement and lifting, which can realize the adjustment of the four contact points with reinforced sheet metal at the longitudinal bottom longitudinal beam of the vehicle body structure a separately, and finally realize the independent control and adjustment of the height of the four contact points to meet the posture of low front and high rear of the frame structure b, which is convenient for the falling and assembly of the vehicle body structure a.

[0063] Furthermore, in order to facilitate the strengthening of sheet metal contact with the longitudinal bottom beam of the longitudinal body, the following settings are made:

[0064] In the first type, a body connection plate 7 is provided on the top of the vertical telescopic assembly 4, and a first connection groove 8 extending in the length direction and a second connection groove extending in the width direction are provided on the body connection plate 7. The body connection plate 7 can increase the contact area, and the provision of the first connection groove 8 and the second connection groove can facilitate the second hydraulic telescopic cylinder and the first hydraulic telescopic cylinder to reduce the friction between the body connection plate 7 and the reinforced sheet metal during the adjustment process, and realize the guide limit, because the reinforced sheet metal can actually be regarded as a convex structure.

[0065] The second one, reference Figure 8 A body connecting plate 7 is provided on the top of the vertical telescopic component 4, and the body connecting plate 7 includes an upper plate portion 700 and a lower plate portion 701 stacked up and down; lubricating oil is coated between the upper plate portion 700 and the lower plate portion 701; a transverse bar 702 is provided on the bottom surface of the upper plate portion 700, and a plurality of plug holes are provided on the transverse bar 702; a sliding groove is provided on the top surface of the lower plate portion 701, and a clamping rod 703 is provided at the bottom of the lower plate portion 701, and the clamping rod 703 passes through the sliding groove and is plugged into a plug hole on the transverse bar 702.

[0066] Such a structure can also prevent the second hydraulic telescopic cylinder and the first hydraulic telescopic cylinder from causing damage to the vehicle body structure a during the adjustment process and provide guidance; due to the reinforced sheet metal connection between the upper plate 700 and the longitudinal bottom longitudinal beam of the longitudinal vehicle body, the relative position is fixed during the adjustment process, and the lower plate 701 moves, and after moving into position, it is locked and limited by the clamping rod 703 and the transverse bar 702. Such a vehicle body connecting plate 7 with a locking function ensures that the vehicle body structure a will not fall over during the adjustment process.

[0067] In some preferred embodiments, the vehicle body support plate 1 is provided with a handrail 9 on one side in the length direction; in the length direction, the frame horse stool avoidance groove 5 extends from the side of the vehicle body support plate 1 away from the handrail 9 to the side close to the handrail 9; the length of the frame horse stool avoidance groove 5 is less than the length of the vehicle body support plate 1. The number of the frame horse stool avoidance groove 5 is one, and the frame horse stool avoidance groove 5 is used to avoid the frame horse stool 10 as a whole; or,

[0068] There are two frame stool avoidance grooves 5 distributed in the width direction; the width of each frame stool avoidance groove 5 is greater than the support legs 11 used to avoid the frame stool 10; the distance between the frame stool avoidance grooves 5 is less than the distance between the two legs 11 of the frame stool 10.

[0069] The above explains the structural form of the frame saddle avoidance groove 5, which can achieve the avoidance of the frame saddle 10 as a whole, or only avoid the support leg 11. The original body structure a and the body support plate 1 are transferred as a whole, and after being transferred to the right place, the body structure a is lifted and separated from the body support plate 1; when falling, from top to bottom, it is the body structure a, the frame structure b, the frame saddle 10 and the body support plate 1, which can be regarded as a whole of the body structure a and the body support plate 1, and the frame saddle 10 and the frame structure b are deformed in a cross position.

[0070] Second, reference Figure 4-Figure 7 A method for assembling an auxiliary frame and a vehicle body is provided, which comprises the following steps:

[0071] Provide auxiliary frame and body assembly equipment;

[0072] Step 100, placing the vehicle body structure a on the vertical telescopic assembly 4 of the vehicle body support plate 1 and connecting them via the vehicle body connecting plate 7;

[0073] Step 101, adjust the transverse telescopic assembly 3 and the vertical telescopic assembly 4 so that the height of the vehicle body structure a is greater than the height of the frame structure b, and form a space for the frame saddle 10 and the frame structure b to pass through; this step provides the necessary conditions for directly pushing in the vehicle body support plate 1;

[0074] Step 102, push the vehicle body support plate 1 into the frame saddle 10, and after it is located directly below the frame structure b, the vertical telescopic assembly 4 is retracted to make the vehicle body structure a fall on the frame structure b;

[0075] Step 103, after the vehicle body structure a and the frame structure b are assembled, the vehicle body pallet 1 is directly taken out in the reverse direction to carry out the next work; or the assembled vehicle body structure a and the frame structure b are lifted as a whole, and the whole is removed from the frame saddle 10, and then lowered and placed on the vehicle body pallet 1, and used as a temporary transfer tool to facilitate transportation, save other equipment, and realize the use of the auxiliary frame and body assembly equipment in various scenarios.

[0076] In some preferred embodiments, step 102, adjusting the transverse telescopic assembly 3 and the vertical telescopic assembly 4 so that the height of the vehicle body structure a is greater than the height of the frame structure b, and forming a space for the frame horse stool 10 and the frame structure b to pass through, specifically includes the following steps:

[0077] Adjust the distance between the two sets of transverse telescopic components 3 in the width direction of the vehicle body support plate 1 so that a space is formed between the two sets of transverse telescopic components 3 for the frame saddle 10 and the frame structure b to pass through;

[0078] The vertical telescopic assembly 4 is extended to drive the vehicle body structure a to move upward until the height of the vehicle body structure a is greater than the height of the frame structure b.

[0079] It is possible to adjust the vertical telescopic component 4 first and then adjust the lateral telescopic component 3, or to adjust the lateral telescopic component 3 first and then adjust the vertical telescopic component 4.

[0080] For the specific adjustment process and the state before the fall, please refer to Figure 4-Figure 7 Description:

[0083] Figure 7 The state in which the transverse telescopic assembly 3 is transversely telescoped is shown, forming a space for the frame saddle 10 and the frame structure b to pass through, avoiding interference with the frame saddle 10 and the frame structure b;

[0084] Figure 4 It is shown that after the adjustment is completed, the vehicle body support plate 1 is pushed in, and then a state is formed in which the vehicle body structure a, the frame structure b, the frame saddle 10 and the vehicle body support plate 1 are arranged from top to bottom when falling.
