Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts assembly technology, and in particular to a front crossbeam pre-assembly device and a front crossbeam assembly equipment. Background Technology
[0002] The assembly of truck front crossbeam modules is a crucial step in the truck manufacturing process, impacting the strength and safety of the vehicle body structure. Front crossbeams, typically made of high-strength steel or aluminum alloy, support the engine, suspension system, and steering knuckles connecting the wheels. Current front crossbeam assembly operations are performed entirely on an assembly platform with a production cycle of 450 seconds. This includes 300 seconds for operators to assemble parts on the platform and 150 seconds for the platform equipment to operate automatically. During the automatic operation, operators must wait for the equipment to complete before assembling the next front crossbeam; this is ineffective waiting time and significantly impacts assembly efficiency. Utilizing the 150 seconds of automatic platform operation to pre-assemble the next front crossbeam module on a pre-assembly table before transporting it to the platform equipment would effectively improve assembly efficiency.
[0003] Existing assembly devices, such as the utility model patent for a front spring front bracket crossbeam welding assembly (CN210937899U), use the support of grooves in the support plate. Two clamps respectively perform the first step of axial fixation on the far ends of the two parts to be welded. Under the axial drive of the second drive device, the near ends of the two parts to be welded come into contact, completing the second step of axial fixation. Under the radial drive of the first drive device, the side pressure plate on the side plate drives the third step of radial fixation on the parts to be welded. Through multiple fixations, displacement during welding is avoided, which could lead to welding errors and ensure welding quality. This device has high positioning accuracy, but the operation is relatively cumbersome. Assembling each front crossbeam requires starting two drive devices, which is time-consuming and does not improve assembly efficiency. Moreover, during the pre-assembly process, it is necessary to align the threaded holes of various components of the front crossbeam and pre-insert bolts. However, the opening positions of the components of different models of front crossbeams vary greatly, and the above device cannot complete the pre-assembly of different models of front crossbeams. Utility Model Content

[0050] Example 1
[0051] See Figure 1 As shown in the figure, an embodiment of this application provides a front crossbeam pre-assembly device, comprising:
[0052] Operating frame 1;
[0053] Central support component 2 is located in the middle of the operating frame 1;
[0054] Side support assembly 3 is provided on the side of the operating frame 1;
[0055] The top of the central support assembly 2 is provided with a groove 221, and the top of the side support assembly 3 is provided with a positioning post 323. Each part of the front crossbeam is placed on the central support assembly 2 through the groove and on the side support assembly 3 through the positioning post 323.
[0056] The front crossbeam is assembled from multiple parts, generally including the front crossbeam assembly, the left extended beam of the frame, the right extended beam of the frame, the front spring front bracket crossbeam, the right front bracket-front leaf spring, and the left front bracket-front leaf spring. Each part has several threaded holes, and adjacent parts are fastened together with bolts. When using this pre-assembly device, first place the first part of the front crossbeam on the side support assembly 3, and insert the positioning pin 323 into the pre-set positioning hole of the first part to achieve positioning of the first part in the horizontal and vertical directions. Place the second part of the front crossbeam in the groove 221 of the middle support assembly 2 to achieve positioning of the second part in the horizontal direction. The operator pre-inserts the bolts into the threaded holes on the first and second parts to achieve pre-assembly of the first and second parts. Repeat the above process to achieve pre-assembly of the entire front crossbeam. During the automatic operation of the assembly platform, the operator can pre-assemble the next front crossbeam on the pre-assembly device, eliminating unnecessary waiting time and improving assembly efficiency; by setting positioning columns, the positioning effect can be improved, thus increasing assembly efficiency.
[0057] Furthermore, when the groove 221 of the central support component 2 is a semicircle with a diameter of 85mm, and the positioning post 323 is 20mm high and 15mm in diameter, it has a better performance.
[0058] Example 2
[0059] See Figure 2-5 As shown, this application embodiment also provides a front crossbeam pre-assembly device, the middle support component 2 including:
[0060] The first adjustment component 21 has two ends connected to the front and rear ends of the operating frame 1, respectively.
[0061] The support plate 22 has its bottom located in the middle of the first adjustment component 21, and its top has a groove 221.
[0062] By adjusting the first adjustment component 21, the position of the middle support component 2 can be changed to accommodate the assembly of different models of front crossbeams.
[0063] See Figure 2-4 As shown, the first adjustment component 21 includes:
[0064] The first threaded rod 211 has two ends that are rotatably connected to the front and rear ends of the operating frame 1, respectively.
[0065] The first slide rod 212 is arranged parallel to the first threaded rod 211, and the two ends of the first slide rod 212 are fixedly connected to the front and rear ends of the operating frame 1, respectively.
[0066] The connecting rod 213 has its first end screwed to the first threaded rod 211, and its second end sleeved on the first sliding rod 212. The bottom of the support plate 22 is installed on the upper end of the second end of the connecting rod 213.
[0067] The first end of the connecting rod 213 is screwed to the first threaded rod 211, and the second end is sleeved on the first slide rod 212. Rotating the first threaded rod 211 causes the connecting rod 213 to slide along the first slide rod 212 to the target position, thereby ensuring that the support plate 22 can provide good support for front crossbeam parts of different models.
[0068] See Figure 2-4 As shown, there are two first slide rods 212, which are symmetrically arranged on the left and right sides of the first threaded rod 211. The first end of the connecting rod 213 is screwed to the first threaded rod 211. The second end and the third end of the connecting rod 213 are respectively sleeved on the two first slide rods 212. There are two support plates 22, and the bottoms are respectively installed on the upper ends of the second and third ends of the connecting rod 213.
[0069] Two first slide rods 212 are provided so that the first threaded rod 211 can drive the connecting rod 213 to slide more smoothly on the first slide rods 212.
[0070] See Figure 3-4 As shown, the central support component 2 has at least two sets, and the connecting rod 213 of each set of central support components 2 has a different length.
[0071] Multiple sets of central support components 2 are provided, with each set having a different length of connecting rod 213 to better support longer front crossbeam parts. Furthermore, when there are bends in the parts, the relative positions of the central support components 2 can be flexibly adjusted to accommodate front crossbeam parts of different shapes. The first threaded rod 211 of each set of central support components 2 can be positioned in the same vertical plane. By changing the height of the support plate 22 or adding vertical sections of different heights to the second end of the connecting rod 213, it can be ensured that the different sets of central support components 2 do not interfere with each other.
[0072] See Figure 2 , 5 As shown, the side support assembly 3 includes:
[0073] The second adjustment component 31 has two ends connected to the front and rear ends of the operating frame 1, respectively.
[0074] The support bracket 32 has its bottom mounted on the second adjustment component 31, and its top is provided with a positioning post 323.
[0075] There are generally two side support components 3, which are located in the frame 11 on the left and right sides of the operating frame 1 respectively. The second adjustment component 31 is connected to the front and rear ends of the frame 11. By adjusting the second adjustment component 31, the position of the support bracket 32 can be changed so as to be suitable for the assembly of different models of front crossbeams.
[0076] See Figure 2 , 5 As shown, the second adjustment component 31 includes:
[0077] The second threaded rod 311 has two ends that are rotatably connected to the front and rear ends of the operating frame 1, respectively.
[0078] The second slide rod 312 is arranged parallel to the second threaded rod 311, and the two ends of the second slide rod 312 are fixedly connected to the front and rear ends of the operating frame 1, respectively.
[0079] The bottom of the slide table 313 and the support bracket 32 are installed on the slide table 313. The first end of the slide table 313 is screwed to the second threaded rod 311, and the second end of the slide table 313 is sleeved on the second slide rod 312.
[0080] The two ends of the second threaded rod 311 are rotatably connected to the front and rear ends of the frame 11, respectively. The first end of the slide table 313 is screwed to the second threaded rod 311, and the second end of the slide table 313 is sleeved on the second slide rod 312. Rotating the second threaded rod 311 drives the slide table 313 to slide along the second slide rod 312 to the target position, thereby ensuring that the support bracket 32 can provide good support for front crossbeam parts of different models.
[0081] See Figure 2 , 5 As shown, the support bracket 32 includes:
[0082] At least two support columns 321 are provided, and the bottom of the support column 321 is set on the slide table 313;
[0083] Connector 322 is installed on the top of support column 321, and positioning column 323 is installed on the upper surface of connector 322.
[0084] Because the parts placed on the support bracket are relatively heavy, a support column 321 is used, which has a good support effect. The connector 322 has a bearing surface so that the right front bracket-front leaf spring and the left front bracket-front leaf spring can be stably placed on the support bracket 32.
[0085] See Figure 2As shown, the first threaded rod 211 and / or the second threaded rod 311 are provided with handles.
[0086] The handle allows the operator to easily rotate the first threaded rod 211 and the second threaded rod 311.
[0087] Example 3
[0088] This application provides a front crossbeam assembly device, including the aforementioned front crossbeam pre-assembly device.
[0089] The working principle of this utility model is as follows:
[0090] Based on the model of the front crossbeam, rotating the first threaded rod 211 moves the support plate 22 to a suitable position, and rotating the second threaded rod 311 moves the support bracket 32 to a suitable position. The first part of the front crossbeam is placed on the support bracket 32, and the positioning pin 323 is inserted into the pre-set positioning hole of the first part, thus achieving horizontal and vertical positioning of the first part. The second part of the front crossbeam is placed in the groove 221 of the central support component 2, thus achieving horizontal positioning of the second part. The operator pre-inserts bolts into the threaded holes on the first and second parts, thus achieving pre-assembly of the front crossbeam. During the automatic operation of the assembly platform, the operator can pre-assemble the next front crossbeam on the pre-assembly device, eliminating unnecessary waiting time and improving assembly efficiency.
