Description

Technical Field

[0001] The utility model relates to the technical field of distributor installation, in particular to a distributor bracket seat welding device. Background Art

[0002] Currently, agricultural vehicles are required to be equipped with distributors, which distribute fluids into different channels for processing. In automated production processes, distributors are often used to distribute fluids to different processing units, controlling the flow of fluids within a controlled timeframe. By using distributors, fluids can be accurately controlled and processed, improving production efficiency and quality.

[0003] The specific installation process is to first install the distributor bracket on the agricultural vehicle. The preferred design is to install the distributor bracket on the bridge housing of the rear axle assembly. The purpose of installing the distributor bracket on the rear axle bridge housing is to prevent water, dust and other debris from damaging the distributor in harsh driving environments of the agricultural vehicle. In order to ensure the firmness of the distributor bracket on the bridge housing, it is necessary to use welding to position it in the designated area of ​​the bridge housing. At this time, it is necessary to manually hold the distributor bracket with one hand for a long time to achieve docking between it and the rear axle bridge housing, and use the other hand to hold the welding tool to weld the docking position of the two. This is relatively labor-intensive, and the manual position needs to be continuously changed during the welding process to achieve multi-point welding. The welding efficiency and degree of automation need to be improved. Utility Model Content

[0004] The purpose of the present invention is to solve the problems raised in the above background technology, and then proposes a distributor bracket seat welding device.

[0006] A distributor bracket seat welding device includes a mounting frame and a bracket with a U-shaped main body. The mounting frame is provided with a clamping component for automatically deflecting the rear axle bridge housing, symmetrically distributed telescopic components and an automatic welding robot. Each telescopic component is connected to a limit seat, and the limit seat is provided with a limit groove adapted to a local area of ​​the rear axle bridge housing. Nuts and through holes connected to the through holes of the nuts are symmetrically provided on the bracket. A mounting bolt passing through the through hole is provided in the nut. The bracket is also provided with a mounting component to enable magnetic adsorption with the mounting area of ​​the rear axle bridge housing to complete preliminary positioning.

[0007] This device can realize efficient welding of the distributor bracket to the rear axle bridge housing, and during the welding process, there is no need for manual work to hold the bracket for a long time with one hand and hold the welding tool with the other hand to weld, thereby significantly reducing the labor intensity during the welding process. The automatic welding robot and the automatic clamping and deflection of the rear axle bridge housing can realize accurate spot welding of the multi-point contact positions of the two, which makes the welding process more intelligent, convenient and efficient, thereby significantly improving the welding work efficiency.

[0008] Furthermore, the clamping assembly includes a first cylinder, a servo motor, a clamping plate and a second cylinder. The first cylinder and the second cylinder rotatably connected to the first cylinder are fixed on the mounting frame. The first cylinder is connected to the servo motor, and the servo motor and the second cylinder are both connected to the clamping plate.

[0009] The above solution can achieve accurate clamping and fixation of both sides of the rear axle housing through the clamping component, the telescopic component and the limit seat, and does not hinder the movement of the rear axle housing during the subsequent deflection process.

[0010] Furthermore, the clamping plate is provided with auxiliary positioning columns to further extend into the inner tubes of the sleeves on both sides of the rear axle housing to prevent the clamping plate and the rear axle housing from detaching.

[0011] The above solution can extend into the inner tubes of the sleeves on both sides of the rear axle housing through the auxiliary positioning columns while clamping, thereby further improving the clamping stability during the subsequent deflection process.

[0012] Furthermore, the mounting assembly includes a U-shaped platform, a mounting rod, an electromagnet and a fixing part. A U-shaped platform is movably provided in the middle of the inner side of the bracket. A mounting rod matching its width is fitted inside the U-shaped platform. An electromagnet that fits into a local area of ​​the rear axle housing is provided at one end of the mounting rod. The mounting rod and the U-shaped platform are movably connected via a fixing part.

[0013] Furthermore, the fixing member is a fixing bolt, and threaded holes are symmetrically arranged on the U-shaped platform. Fixing bolts are arranged in the threaded holes, and one end of the fixing bolts is in contact with the mounting rod.

[0014] The above solution can achieve magnetic adsorption of the bracket and the local installation area of ​​the rear axle housing before welding by installing components, so that there is no need for long-term manual intervention to complete the docking before welding, thereby reducing the labor intensity of the operation and reducing safety hazards.

[0015] Furthermore, the bracket is made of high-strength stainless steel and is integrally formed.

[0016] Furthermore, a rubber layer is provided on the surface of the clamping plate.

[0017] The above solution can avoid the probability of damage to the rear axle housing caused by hard contact between the clamping plate and the rear axle housing through the rubber layer, and can also increase the friction between the clamping plate and the rear axle housing, thereby further improving the clamping stability.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0025] like Figure 1 and Figure 2As shown, a distributor bracket 3 welding device includes a mounting frame 1 and a bracket 3 with a U-shaped main body (the bracket 3 is made of high-strength stainless steel and is integrally formed). The mounting frame 1 is provided with a clamping assembly for automatic deflection of the rear axle bridge housing 2, a symmetrically distributed telescopic assembly 16 (the telescopic assembly 16 can use either an electric cylinder or an electric push rod) and an automatic welding robot. The automatic welding robot is not shown in the figure and belongs to the existing technology and no improvement is made. Each telescopic assembly 16 is connected to a limit seat 17. The limit seat 17 is provided with a limit groove adapted to a local area of ​​the rear axle bridge housing 2. The limit groove is not shown in the figure. The bracket 3 is symmetrically provided with a nut 31 and a through hole 32 connected to the through hole of the nut 31. The nut 31 is provided with a mounting bolt passing through the through hole 32 and used to connect and fix the distributor (the mounting bolt is not shown in the figure). The bracket 3 is also provided with a mounting assembly that completes preliminary positioning by magnetic adsorption with the mounting area of ​​the rear axle bridge housing 2.

[0026] Specifically, the clamping assembly includes a first cylinder 11, a servo motor 12, a clamping plate 13 and a second cylinder 15. The first cylinder 11 is fixedly installed on the mounting frame 1 and the second cylinder 15 is rotatably connected to the first cylinder 11. The first cylinder 11 is connected to the servo motor 12, and the servo motor 12 and the second cylinder 15 are both connected to the clamping plate 13.

[0027] Specifically, the mounting assembly includes a U-shaped platform 33, a mounting rod 34, an electromagnet 35, and a fixing piece. The U-shaped platform 33 is movably provided in the middle of the inner side of the bracket 3. The U-shaped platform 33 is fitted with a mounting rod 34 that matches its width. One end of the mounting rod 34 is provided with an electromagnet 35 that fits in a local area of ​​the rear axle housing 2. The mounting rod 34 and the U-shaped platform 33 are movably connected by a fixing piece.

[0028] The above embodiment is further optimized, the fixing member is a fixing bolt 36, and threaded holes are symmetrically provided on the U-shaped platform 33 (the threaded holes are not shown in the figure), and the fixing bolt 36 is provided in the threaded hole and one end of the fixing bolt 36 is in contact with the mounting rod 34.

[0029] It should be noted that the automatic welding robot, the first cylinder 11 , the servo motor 12 , the second cylinder 15 , the telescopic assembly 16 and the electromagnet 35 are all electrically connected to the controller, which is not shown in the figure.

[0030] The workflow of this utility model:

[0031] First, the local areas on both sides of the rear axle housing 2 are accurately and stably placed in the limiting grooves of the two limiting seats 17 to complete the position definition (the telescopic height of the telescopic assembly 16 in the initial state is as shown in the appendix of the manual). Figure 1, and the rear axle housing 2 is lifted and lowered ... When the rear axle housing 2 is in contact with the two legs of the bracket 3, the two legs of the bracket 3 also contact the rear axle housing 2. Then the controller controls the electromagnet 35 to be energized to realize the preliminary adsorption and positioning between the bracket 3 and the rear axle housing 2. After the adsorption is completed, the controller controls the servo motor 12 to work to realize the uniform rotation of the rear axle housing 2. At the same time, the bracket 3 also rotates together with the rear axle housing 2. Then, the automatic welding robot can be used to perform multi-point welding on the contact positions of the bracket 3 and the rear axle housing 2. During the welding process, the rear axle housing 2 can change its orientation according to a preset program, thereby significantly improving the comprehensiveness and automation of welding. After the welding of the rear axle housing 2 and the bracket 3 is completed, the controller first controls the electromagnet 35 to be de-energized (it should be noted that the contact surface between the electromagnet 35 and the rear axle housing 2 is not welded), and then loosens the fixing bolts to remove the mounting rod 34 from the U-shaped platform 33. Then, the distributor can be fixed to the bracket 3 by the mounting bolts.

[0032] Compared with the existing technology, this device can realize efficient welding of the distributor bracket 3 to the rear axle bridge housing 2, and during the welding process, there is no need for manual work to hold the bracket 3 for a long time with one hand and hold the welding tool with the other hand for welding, thereby significantly reducing the labor intensity during the welding process. The automatic welding robot and the automatic clamping and deflection of the rear axle bridge housing 2 can achieve accurate spot welding of multiple contact positions between the two. The welding program can be pre-set in the controller, which makes the welding process more intelligent, convenient and efficient, thereby significantly improving the welding work efficiency.

[0033] In some embodiments, as Figure 1 As shown, auxiliary positioning columns 14 are provided on the clamping plate 13 to further extend into the inner tubes of the sleeves on both sides of the rear axle housing 2 to prevent the clamping plate 13 and the rear axle housing 2 from detaching; this embodiment can extend into the inner tubes of the sleeves on both sides of the rear axle housing 2 while clamping through the auxiliary positioning columns 14, thereby improving the clamping stability during the subsequent deflection process.

[0034] The above embodiment is a further optimization of the scheme, in which a rubber layer is provided on the surface of the clamping plate 13, which is not shown in the figure. This embodiment can avoid the probability of damage to the rear axle housing 2 caused by hard contact between the clamping plate 13 and the rear axle housing 2 through the rubber layer, and at the same time can increase the friction between the clamping plate 13 and the rear axle housing 2, thereby further improving the clamping stability.
