Technical Field

[0001] The present invention belongs to the technical field of bridge housing welding equipment, and particularly relates to a flipping welding equipment for a bridge housing reinforcing ring. Background Art

[0002] An existing bridge housing assembly generally includes a rear bridge housing body, a reinforcing ring, and a rear bridge housing cover. Among them, the reinforcing ring is used to realize the screw connection and assembly of the rear bridge housing assembly and the main reducer. The reinforcing ring and the rear bridge housing cover are fixed on the rear bridge housing body by means of a circumferential weld, and an oil filler plug hole is provided on the rear bridge housing cover.

[0003] Most of the existing welding equipment for welding the reinforcing ring to the bridge housing body directly clamps and fixes the bridge housing body to the welding table of the welding equipment, and then places the reinforcing ring at the welding position of the bridge housing body. At this time, the operator needs to continuously adjust the angle and position of the welding torch of the welding mechanism to weld the reinforcing ring to the bridge housing body. Obviously, this welding method will relatively affect the welding accuracy of the reinforcing ring on the bridge housing body, and at the same time, it is easy to affect the welding quality and welding efficiency. Summary of the Invention

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0005] The present invention is a flipping welding equipment for a bridge housing reinforcing ring, including a base body. On the base body, vertical brackets that slide are symmetrically arranged through a driving sliding mechanism, and a welding mechanism is arranged on one side of the base body;

[0006] Each vertical bracket is provided with a driving flipping mechanism. The driving flipping mechanism includes a gear assembly. The gear assembly is arranged on the back of the vertical bracket, and a shaft tube is connected to the gear assembly. The shaft tube rotates and extends out of the outer side of the vertical bracket and is connected with a clamping disc. The symmetric clamping discs are in contact with the two end parts of the bridge housing body to be welded;

[0007] A clamping and positioning mechanism is arranged between the symmetric vertical brackets. The clamping and positioning mechanism is located at the center of the bridge housing body and is used to clamp and position the reinforcing ring on the upper surface at the center of the bridge housing body.

[0008] Further, the driving and flipping mechanism further includes a pushing disk, which is fixedly arranged at the outer end of the shaft tube. At least two guiding long grooves are formed on the outer circumferential surface of the shaft tube along its length direction. The driving gear of the gear assembly is sleeved on the shaft tube, and at least two protruding blocks are formed on the inner circumferential surface of the driving gear. Each protruding block slides and inserts into each guiding long groove. The driving gear is rotatably installed on the back side of the vertical bracket through a rotating ring. The clamping disk is also rotatably installed on the other side of the vertical bracket through a rotating ring, and the clamping disk is sleeved on the sliding shaft tube. At least two protruding blocks are also formed on the inner circumferential surface of the clamping disk, and each protruding block also slides and inserts into each guiding long groove. An annular groove is formed on the outer circumferential surface of the pushing disk, and at least two supporting blocks are slidably inserted into the annular groove. Each supporting block is respectively connected to the output rod of the cylinder parts fixedly arranged on the front and rear sides of the vertical bracket.

[0009] Further, a bottom strip is fixedly arranged at the bottom of the guiding long groove, and a sac-shaped strip is arranged on the upper surface of the bottom strip. The upper surface of the sac-shaped strip contacts with the protruding block. An air guide pipe is communicated with the outer end of the sac-shaped strip. The symmetric shaft tubes are inserted into the bridge shell body.

[0010] Further, the clamping and positioning mechanism includes a central cylinder, which is inserted into the bridge shell body. Symmetric positioning jacks are formed on the outer circumferential surface of the central cylinder. A positioning insertion rod is slidably arranged at the inner end of the shaft tube, and the positioning insertion rod is connected to the output shaft of the cylinder part fixedly arranged inside the shaft tube. The outer end of the positioning insertion rod slides and inserts into the positioning jack. A plurality of U-shaped seats are fixedly arranged in a circumferential array on the upper end surface of the central cylinder, and a clamping rod is hinged in each U-shaped seat. A clamping block is installed at the end of each clamping rod far away from the central cylinder. The ends of the plurality of clamping rods close to the central cylinder are in contact with a pushing and resetting assembly arranged inside the central cylinder.

[0011] Further, the pushing and resetting assembly includes a pushing plug body, which slides and inserts into the central hole of the central cylinder. The upper end surface of the pushing plug body contacts with the plurality of clamping rods. The lower surface of the pushing plug body is connected with a pushing column through a connecting column, and the bottom of the pushing column is connected with the bottom of the central cylinder through a spring part. The positioning jack penetrates into the central cylinder. An inclined pushing block is formed at the outer end of the positioning insertion rod. The distance from the bottom of the pushing column to the bottom of the positioning jack is the same as the height of the end of the inclined pushing block.

[0012] Further, a hidden groove is formed on the upper surface of the end of the positioning insertion rod close to the inclined pushing block, and a positioning column is slidably inserted into the hidden groove. The bottom of the positioning column is connected with a sac-shaped tube, and the sac-shaped tube is communicated with the air guide pipe arranged inside the positioning insertion rod.

[0013] Further, a plurality of supporting blocks are fixedly arranged at the positions where the inner wall of the central cylinder is misaligned with the positioning jack, and the bottom of the supporting block is flush with the lower hole wall of the positioning jack. The height of the supporting block is the same as the height of the end of the inclined pushing block far away from the positioning insertion rod.

[0014] Furthermore, the driving and sliding mechanism includes a protective box. The upper opening of the protective box is open. A double-threaded lead screw is rotatably arranged inside the protective box. Symmetrical lead screw nuts are sleeved on the double-threaded lead screw, and M-shaped sliders are connected to the symmetrical vertical brackets. The two vertical blocks on both sides of the M-shaped slider are located outside the protective box. A segmented sealing film is slidably arranged at the upper opening of the protective box, and each segment of the sealing film is respectively connected to the M-shaped slider and the side wall of the upper opening.

[0015] The present invention has the following beneficial effects:

[0016] 1. By arranging symmetrical and slidable vertical brackets on the base body, the driving and sliding mechanism can drive the symmetrical vertical brackets to approach or move away from each other, and the corresponding two clamping discs can approach or move away from each other, so as to facilitate clamping and supporting the bridge shell body of different lengths. The reinforcing ring to be welded can be pressed and positioned by the pressing and positioning mechanism to be tightly attached to the upper surface of the central hole of the clamped bridge shell body. The continuous flipping of the bridge shell body will drive the reinforcing ring to flip synchronously, and the phenomenon that the reinforcing ring slips off or skews from the bridge shell body will not occur, thus facilitating the welding torch of the welding mechanism to accurately and stably weld at the welding seam between the bridge shell body and the reinforcing ring.

[0017] 2. By arranging the bladder-shaped strips in the guiding long grooves, when the bladder-shaped strips at both ends of the bridge shell body expand, they will extend out of the guiding long grooves and abut against the inner wall of the bridge shell body to realize the limiting and gravity support of the bridge shell body, preventing the bridge shell body from falling or skewing during flipping. When the bladder-shaped strips outside the gear assembly expand, and the expanded height extends out of the guiding long grooves, the expanded bladder-shaped strips will be located on both sides of the gear assembly and the clamping disc, which can play a role in limiting the axial direction of the shaft tube. When the shaft tube drives the clamping disc to rotate, due to the free sliding of the shaft tube in the bridge shell body, the safe and stable limiting and gravity support of the shaft tube to the bridge shell body will be affected, thus affecting the accuracy and efficiency of the welding of the reinforcing ring on the bridge shell body.

[0018] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. Description of the Drawings

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0029] Please refer to Figures 1-6As shown in the figure, the present invention is a flipping and welding device for a bridge shell reinforcing ring, including a base body 1. On the base body 1, there are symmetrically arranged vertical brackets 3 that can slide through a driving sliding mechanism 2, and a welding mechanism is arranged on one side of the base body 1; a driving flipping mechanism 4 is arranged on each vertical bracket 3. The driving flipping mechanism 4 includes a gear assembly 41. The gear assembly 41 is arranged on the back of the vertical bracket 3, and a shaft tube 42 is connected to the gear assembly 41. The shaft tube 42 rotates and extends out of the outer side of the vertical bracket 3 and is connected with a clamping disc 43. The symmetric clamping discs 43 are in contact with the two end parts of the bridge shell main body 7 to be welded; a pressing and positioning mechanism 5 is arranged between the symmetric vertical brackets 3. The pressing and positioning mechanism 5 is located at the center of the bridge shell main body 7 and is used to clamp and position the reinforcing ring 8 on the upper surface at the center of the bridge shell main body 7.

[0030] Specifically, in the present invention, by arranging symmetric and slidable vertical brackets 3 on the base body 1, the driving sliding mechanism 2 can drive the symmetric vertical brackets 3 to approach or move away from each other, and the corresponding two clamping discs 43 can approach or move away from each other, so as to facilitate the clamping and supporting of bridge shell main bodies 7 of different lengths. The reinforcing ring 8 to be welded can be pressed and fitted onto the upper surface of the central hole of the clamped bridge shell main body 7 through the pressing and positioning mechanism 5. Then, control the servo motor connected to the driving gear of the gear assembly 41 to work, so that the driving gear and the driven gear mesh and drive, thereby facilitating the gear assembly 41 to drive the clamping disc 43 to rotate through the shaft tube 42, realizing the driving and flipping of the clamped and supported bridge shell main body 7. Since the reinforcing ring 8 is pressed and fitted onto the bridge shell main body 7 through the pressing and positioning mechanism 5, therefore, the continuous flipping of the bridge shell main body 7 will drive the reinforcing ring 8 to flip synchronously, and there will be no phenomenon that the reinforcing ring 8 slides off or skews from the bridge shell main body 7. Thus, it is convenient for the welding torch of the welding mechanism to accurately and stably correspond to the welding seam between the bridge shell main body 7 and the reinforcing ring 8 for welding, and it is not necessary for the operator to continuously and frequently change the angle of the welding torch for welding treatment. Therefore, it can not only improve the welding accuracy of the reinforcing ring 8 on the bridge shell main body 7, but also improve its welding efficiency.

[0031] In this embodiment, the driving and flipping mechanism 4 further includes a pushing disk 44. The pushing disk 44 is fixedly arranged at the outer end of the shaft tube 42. At least two guiding long slots 421 are formed in the outer circumferential surface of the shaft tube 42 along its length direction. The driven gear of the gear assembly 41 is sleeved on the shaft tube 42, and at least two protruding blocks 45 are formed on the inner circumferential surface of the driven gear. Each protruding block 45 is slidably inserted into each guiding long slot 421. The driven gear is rotatably mounted on the back side of the vertical bracket 3 through a rotating ring. The clamping disk 43 is also rotatably mounted on the other side of the vertical bracket 3 through a rotating ring, and the clamping disk 43 is sleeved on the slidable shaft tube 42. At least two protruding blocks 45 are also formed on the inner circumferential surface of the clamping disk 43, and each protruding block 45 is also slidably inserted into each guiding long slot 421. An annular groove 441 is formed in the outer circumferential surface of the pushing disk 44, and at least two arc-shaped supporting blocks 46 are slidably inserted into the annular groove 441. Each arc-shaped supporting block 46 is respectively connected to the output rod of a cylinder member 47 fixedly arranged on the front and rear sides of the vertical bracket 3;

[0032] Specifically, in order to further improve the safety of flipping and welding the bridge shell main body 7, prevent the bridge shell main body 7 from falling off the two clamping disks 43 due to its heavy weight, or prevent the two end portions of the bridge shell main body 7 from deforming due to the large clamping force of the clamping disks 43; therefore, when the bridge shell main body 7 to be welded is placed between the symmetrical vertical brackets 3 and the symmetrical clamping disks 43 approach each other, at this time, the symmetrical shaft tubes 42 will first be inserted into the bridge shell main body 7 to support the bridge shell main body 7. When the clamping disks 43 are attached to the two end portions of the bridge shell main body 7, at this time, by retracting the output rod of the cylinder member 47, the pushing disk 44 can be driven by the arc-shaped supporting blocks 46 to slide towards the side of the vertical bracket 3, and then the shaft tube 42 can be pushed to continue to insert into the bridge shell main body 7. Then, with the cooperation of the attached clamping disks 43, not only can the clamping of the bridge shell main body 7 be realized, but also the suspended support of the bridge shell main body 7 can be achieved. Since both the driven gear and the clamping disk 43 are slidably inserted and matched with the guiding long slots 421 through the protruding blocks on the inner circumferential surface, therefore, on the premise of not interfering with the normal sliding of the shaft tube 42, the shaft tube 42 can drive the clamping disk 43 to rotate through the cooperation of the gear assembly 41, so that the suspended and clamped bridge shell main body 7 can be flipped and welded. Since both the driven gear and the clamping disk 43 are rotatably arranged on the two side surfaces of the vertical bracket 3 through rotating rings, the sliding of the shaft tube 42 will not affect the normal rotation of the driven gear and the clamping disk 43, and will not cause the clamping disk 43 to have axial sliding. The clamping disk 43 will only be attached to the two end portions of the bridge shell main body 7 to clamp and flip it, and will not interfere with the normal sliding of the shaft tube 42 to support the bridge shell main body 7 in a suspended manner; and the arc-shaped supporting blocks 46 are relatively slidably inserted into the annular groove 441, so they will not interfere with the rotation of the shaft tube 42 and can drive the shaft tube 42 to slide normally in the axial direction.

[0033] In this embodiment, a bottom strip 48 is fixedly arranged at the bottom of the guiding long groove 421, and a bladder-shaped strip 49 is arranged on the upper surface of the bottom strip 48. The upper surface of the bladder-shaped strip 49 contacts the protruding block 45. An air duct is communicated with the outer end of the bladder-shaped strip 49. The symmetrically arranged shaft tubes 42 are inserted into the bridge housing main body 7;

[0034] Specifically, in order to further improve the insertion of the shaft tube 42 into the bridge housing main body 7 and provide gravity support for it, so that the bridge housing main body 7 will not drop or skew during flipping; when the shaft tubes 42 are inserted into both ends of the bridge housing main body 7, at this time, gas is introduced into the bladder-shaped strip 49 through the air duct, so that the bladder-shaped strip 49 expands outwards in the guiding long groove 421. When the bladder-shaped strip 49 located in the driven gear and the clamping disc 43 expands, it will contact the protruding block 45, increasing the axial friction force between the protruding block 45 and the shaft tube 42. Thus, it is convenient for the driven gear to drive the shaft tube 42 to rotate stably and safely. When the driven gear rotates instantaneously, due to the intermittent gap between the guiding long groove 421 and the protruding block 45, the transmission stability will not be affected;

[0035] When the bladder-shaped strip 49 located at both ends of the bridge housing main body 7 expands, it will extend out of the guiding long groove 421 and contact the inner wall of the bridge housing main body 7, realizing the limit gravity support for the bridge housing main body 7 to prevent the bridge housing main body 7 from dropping or skewing during flipping. When the bladder-shaped strip 49 located outside the gear assembly 41 expands, and the expansion height extends out of the guiding long groove 421. Then, the expanded and extended bladder-shaped strip 49 will be located on both sides of the gear assembly 41 and the clamping disc 43, which can play a role in limiting the shaft tube 42 in the axial direction. When the shaft tube 42 drives the clamping disc 43 to rotate, due to the free sliding of the shaft tube 42 in the bridge housing main body 7, the safe and stable limit gravity support of the shaft tube 42 for the bridge housing main body 7 will be affected, thus affecting the accuracy and efficiency of the welding of the reinforcing ring 8 on the bridge housing main body 7.

[0036] In this embodiment, the pressing and positioning mechanism 5 includes a central cylinder 51. The central cylinder 51 is inserted into the bridge housing main body 7. Symmetric positioning insertion holes 511 are formed on the outer circumference of the central cylinder 51. A positioning insertion rod 52 is slidably arranged at the inner end of the shaft tube 42, and the positioning insertion rod 52 is connected to the output shaft of a cylinder part 47 fixedly arranged inside the shaft tube 42. The outer end of the positioning insertion rod 52 is slidably inserted into the positioning insertion hole 511. A plurality of U-shaped seats 53 are fixedly arranged in a circumferential array on the upper end surface of the central cylinder 51. A clamping rod 54 is hinged in each U-shaped seat 53. A clamping block 55 is installed at the end of each clamping rod 54 far from the central cylinder 51. The ends of the plurality of clamping rods 54 close to the central cylinder 51 are in contact with a top-pushing and resetting assembly 6 arranged inside the central cylinder 51;

[0037] Specifically, after the reinforcing ring 8 is placed on the axle housing body 7 after being clamped and supported, the central cylinder 51 is inserted into the central interior of the axle housing body 7 at this time, so that the positioning jacks 511 on both sides correspond to the pipe orifices of the axle tube 42. Then, the output shaft of the cylinder member 47 in the axle tube 42 extends out, and can push the positioning plug rod 52 to insert into the positioning jack 511, realizing the positioning support for the central cylinder 51. When the positioning plug rod 52 is inserted into the positioning jack 511, at this time, the top-pushing and resetting assembly 6 will push the ends of the plurality of clamping rods 54 at the top of the central cylinder 51 to move upward. Since the clamping rods 54 are hinged to the top of the central cylinder 51 through the U-shaped seats 53, the inclined upward swing of the clamping rods 54 will cause the clamping blocks 55 to press and fit onto the reinforcing ring 8, realizing the pressing and fitting of the reinforcing ring 8 onto the central upper surface of the axle housing body 7. Since the central cylinder 51 is suspended and positioned and supported in the center of the axle housing body 7 through the positioning plug rod 52, therefore, there is no need to set any relevant support mechanism in the axle housing body 7 to support the central cylinder 51, and it can also realize that the flipping of the axle housing body 7 drives the central cylinder 51 to flip synchronously, so that the pressed reinforcing ring 8 can follow the axle housing body 7 to flip synchronously for welding treatment; when the positioning plug rod 52 disengages from the inside of the central cylinder 51 and has not completely disengaged from the positioning jack 511, at this time, the positioning plug rod 52 disengages from pushing the top-pushing and resetting assembly 6, realizing that the clamping blocks 55 at the ends of the plurality of clamping rods 54 disengage from the fitting and pressing of the welded reinforcing ring 8. Then, the positioning plug rod 52 is withdrawn from the positioning jack 511. At this time, since the plurality of clamping blocks 55 are in contact with the reinforcing ring 8, the central cylinder 51 will not fall from the center of the axle housing body 7. Then, the central cylinder 51 is directly taken out upward, and the pressing and positioning mechanism 5 can be quickly taken out of the axle housing body 7, which is convenient for cooperating with the driving and flipping mechanism 4 to repeatedly press and fit the next group of reinforcing rings 8 and axle housing bodies 7.

[0038] In this embodiment, the top-pushing and resetting assembly 6 includes a top-pushing plug body 61. The top-pushing plug body 61 is slidably inserted into the central hole of the central cylinder 51, and the upper end surface of the top-pushing plug body 61 abuts against the plurality of clamping rods 54. The lower surface of the top-pushing plug body 61 is connected with a pushing column 63 through a connecting column 62, and the bottom of the pushing column 63 is connected with the bottom of the central cylinder 51 through a spring member 64. The positioning jack 511 penetrates through to the inside of the central cylinder 51. An inclined pushing block 65 is formed at the outer end of the positioning plug rod 52. The distance from the bottom of the pushing column 63 to the bottom of the positioning jack 511 is the same as the height of the end of the inclined pushing block 65;

[0039] Specifically, when the positioning plug rod 52 is continuously inserted into the positioning jack 511, the end of the inclined push block 65 will pass through the gap between the pushing column 63 and the positioning jack 511 and enter the central cylinder 51. At this time, the inclined surface of the inclined push block 65 will continuously squeeze and push the pushing column 63 upward. At this time, the spring member 64 at the bottom of the pushing column 63 will be stretched. Then, the pushing column 63 will push the pushing plug body 61 to extend out of the central cylinder 51 through the connecting rod and contact the plurality of clamping rods 54, realizing the pushing process of the plurality of clamping rods 54. The height of the upward sliding of the pushing plug body 61 is adjusted according to the length of the inclined push block 65 inserted into the central cylinder 51, so as to facilitate the fitting and pressing of the plurality of clamping blocks 55 at the ends of the plurality of clamping rods 54 on the reinforcing ring 8 with different thicknesses; when the inclined push block 65 exits from the central cylinder 51, at this time, under the elastic pulling of the spring member 64, the pushing plug body 61 will slide downward in the central cylinder 51 to disengage from the pushing of the clamping rod 54, so that the plurality of clamping blocks 55 disengage from the fitting and pressing of the reinforcing ring 8; the positioning plug rod 52 can not only play a role in positioning and suspending the support of the central cylinder 51, but also, under the cooperation of the sliding inserted inclined push block 65 and the pushing column 63, play a role in pushing the pushing plug body 61 to slide upward, thereby improving the stability and accuracy of the fitting and pressing of the plurality of suspended support clamping rods 54 on the reinforcing ring 8, so that the reinforcing ring 8 will not shift or skew during flipping.

[0040] In this embodiment, a hidden groove 521 is formed on the upper surface of the end of the positioning plug rod 52 close to the inclined push block 65, and a positioning column 66 is slidably inserted into the hidden groove 521. The bottom of the positioning column 66 is connected with a bladder tube 67, and the bladder tube 67 is communicated with an air guide tube arranged in the positioning plug rod 52;

[0041] Specifically, when the inclined push block 65 is completely inserted into the central cylinder 51 and the positioning column 66 is also located in the central cylinder 51, the gas filled in the air guide tube will enter the bladder tube 67 at this time, causing it to expand upward in the hidden groove 521, so as to facilitate pushing the positioning column 66 to extend out of the hidden groove 521 and contact the inner wall of the central cylinder 51, so as to facilitate the axial limit sliding of the inserted positioning plug rod 52, preventing the misoperation of the cylinder part 47 in the shaft tube 42, resulting in the positioning plug rod 52 exiting from the positioning jack 511, and thus affecting the positioning and suspending support of the central cylinder 51; when the gas in the bladder tube 67 is extracted, it will contract, and then the positioning column 66 will retract into the hidden groove 521, causing the positioning plug rod 52 to exit from the positioning jack 511, so as to facilitate detaching and removing the pressing and positioning mechanism 5 from the center of the axle housing main body 7.

[0042] In this embodiment, a plurality of support blocks 68 are fixedly provided at positions where the inner wall of the central cylinder 51 is misaligned with the positioning jack 511. The bottom of the support block 68 is flush with the lower hole wall of the positioning jack 511. The height of the support block 68 is the same as the height of the inclined push block 65 away from the end of the positioning rod 52. The upper surface of the support block 68 contacts the bottom of the downward-sliding push column 63;

[0043] Specifically, when the push plug body 61 is retracted into the central cylinder 51, at this time, the plurality of support blocks 68 will suspend and support the push column 63, preventing the spring tension of the spring member 64 from being too large, which may cause the bottom of the push column 63 to slide below the lower hole wall of the positioning jack 511, thereby affecting the upward pushing process of the inclined push block 65 inserted into the central cylinder 51 against the push column 63; and the height of the support block 68 is the same as the height of the end of the inclined push block 65, so that after the push column 63 slides down to the initial position, the distance from the bottom of the push column 63 to the bottom of the positioning jack 511 is the same as the height of the end of the inclined push block 65, which is convenient for the inclined push block 65 to accurately push the push column 63, and it will not interfere with the normal sliding of the push plug body 61 and completely release the pushing process on the clamping rod 54, thereby improving the accuracy of the use of the pressing and positioning mechanism 5.

[0044] In this embodiment, the driving and sliding mechanism 2 includes a protective box 21. The upper box opening of the protective box 21 is in an open state. A double-threaded lead screw 22 is rotatably provided inside the protective box 21. And an M-shaped slider 23 is sleeved on the double-threaded lead screw 22 through symmetric lead screw nuts. The symmetric M-shaped sliders 23 are connected to the symmetric vertical brackets 3. The two vertical blocks on both sides of the M-shaped slider 23 are located outside the protective box 21; A segmented sealing film 24 is slidably provided at the upper box opening of the protective box 21, and each segment of the sealing film 24 is respectively connected to the M-shaped slider 23 and the side wall of the upper box opening;

[0045] Specifically, through the servo motor fixedly provided at the end of the protective box 21, the double-threaded lead screw 22 can be driven to rotate inside the protective box 21, so as to facilitate the symmetric M-shaped sliders 23 to drive the symmetric vertical brackets 3 to approach or move away from each other, so as to facilitate the suspension support and clamping and flipping of the axle housing main body 7 of different sizes. The setting of the sealing film 24 can protect the components such as the double-threaded lead screw 22 inside the protective box 21, preventing the welding slag generated by welding from falling into the protective box 21 and affecting the normal sliding of the M-shaped slider 23.
