Description

Technical Field:

[0001] The present invention relates to the technical field of automotive parts processing equipment, and more particularly to a method for cutting the four-sided risers of a shock tower and a device therefor. Background Art:

[0002] Currently, in an automobile, a shock tower, such as a shock tower located in the engine compartment under the hood, mainly functions to install and fix shock absorbers, and at the same time plays a role in supporting and stabilizing the vehicle body.

[0003] Existing shock towers are formed by casting. After the casting is completed, all the risers on the outer sidewall need to be removed. The existing method is to manually knock and remove the edges with a hammer. This method is likely to break the connection part and cause scrap.

[0004] Therefore, another existing method is to use a vertical saw blade of a vertical cutting machine to cut and remove. It requires manual handling and moving of the shock tower so that the cutting position faces the saw blade for cutting. Since the shock tower is heavy, manual handling and moving are very troublesome and the manual labor intensity is high. Moreover, in order to ensure the accuracy of the cutting position, it also needs to be fixed on a corresponding fixture for cutting one side. Then, after disassembling it, it is rotated 90°, and then fixed on another fixture in this state for fixing, and then cutting is carried out. It requires multiple clamping and rotating the position of the shock tower, which is very troublesome and has a poor effect. Summary of the Invention:

[0005] The object of the present invention is to overcome the deficiencies of the prior art and provide a method for cutting the four-sided risers of a shock tower and a device therefor. It can clamp and fix the shock tower, rotate and position the shock tower as needed, and can move it left and right along the first guide rail, the middle guide rail or the second guide rail to achieve cutting. Its movement is convenient, without multiple disassembly and assembly, greatly reducing the manual labor intensity.

An upper locking nut 236 is screwed onto the top of the middle support screw 23. The bottom surface of the upper locking nut 236 is pressed against the top surface of the locking piece 234. The bottom surface of the locking piece 234 is pressed against the top surface of the upper pressing cushion plate 233. The bottom surface of the upper pressing cushion plate 233 is pressed against the top surface of the product 100.

[0084] Furthermore, the maximum width of the upper locking nut 236 is smaller than the inner diameter of the middle through hole of the upper pressing pad 233.

[0085] Furthermore, a positioning connection seat 80 is fixed on the top surface of the top plate of the frame 50 at the front part on the right side of the first guide rail 51. An upwardly extending front limit connection block 81 is formed on the top surface of the front part of the positioning connection seat 80. A middle positioning groove 82 extending obliquely downward is formed on the top surface of the front limit connection block 81. A front positioning groove 83 is formed on the front side wall of the front limit connection block 81. A first quick clamp 84 and a second quick clamp 85 (the ends of the first quick clamp 84 and the second quick clamp 85 in this embodiment are hook parts, and the rest are the same as the existing convention, so they will not be described in detail here) are fixed on the top surface of the rear part of the positioning connection seat 80. Two downwardly extending adjustment through grooves 86 are formed in the middle of the top surface of the front limit connection block 81. The adjustment through grooves 86 communicate with the middle positioning groove 82 and the front positioning groove 83. The rod parts of the first quick clamp 84 and the second quick clamp 85 are inserted into the corresponding adjustment through grooves 86. Among them, a lower groove is formed on the bottom corresponding to the handle of the second quick clamp 85 on the moving fixing plate 10.

[0087] The second transverse clamping rod 242 faces the front positioning groove 83, and the hook part of the second quick clamp 85 faces the annular groove formed on the outer side wall of the middle part of the second transverse clamping rod 242. In some of the drawings of this embodiment, in order to make other components clearly shown, the positioning connection seat and the components thereon are not shown.

[0088] Furthermore, the outer side wall of the top of the middle positioning cylindrical block 231 is a conical wall surface, with a smaller outer diameter at the upper end and a larger outer diameter at the lower end. This structure facilitates the insertion of the middle positioning cylindrical block 231 from bottom to top into the middle circular through hole 101 of the shock tower 100.

[0089] Furthermore, an extending part extending backward is formed on the rear wall surface of the upper part of the vertical plate of the clamping seat 14, and a rear clamping groove 141 with an arc-shaped inner side wall is formed on the rear wall surface of the extending part.

[0090] Furthermore, the upper part of the stepped insertion through-hole 151 is a small-diameter hole section, and the lower part is a large-diameter hole section. A radially extending edge 162 is formed on the outer side wall of the bottom of the rear positioning post 16, which is inserted into the large-diameter hole section. Its outer diameter is larger than the inner diameter of the small-diameter hole section. A spring 152 is inserted into the large-diameter hole section. A lower end cover 17 is fixed to the rear bottom surface of the intermediate connecting block 15. The lower end cover 17 covers the bottom end of the stepped insertion through-hole 151. The bottom end of the spring 152 bears on the top surface of the lower end cover 17, and the top end bears on the bottom surface of the rear positioning post 16.

[0091] Furthermore, a vertical guiding through-channel 153 is formed on the rear wall surface of the intermediate connecting block 15. The top end of the vertical guiding through-channel 153 extends out of the top surface of the intermediate connecting block 15. The vertical guiding through-channel 153 communicates with the small-diameter hole section of the stepped insertion through-hole 151. The screw part of the guiding bolt 165 is inserted into the vertical guiding through-channel 152, and its end is screwed onto the rear positioning post 16. The rotating part of the guiding bolt 165 is located outside the rear wall surface of the intermediate connecting block 15.

[0092] Furthermore, a spherical concave hole is formed in the middle of the top surface of the vertical column 11. An installation cover 13 is fixed on the top surface of the vertical column 11. A spherical concave hole extending upward is formed in the middle of the bottom surface of the installation cover 13. The middle part of the spherical concave hole extends out of the top surface of the installation cover 13. The universal ball 12 is clamped between the spherical concave hole and the upper spherical concave hole. Lubricating grease is applied to the inner side walls of the spherical concave hole and the upper spherical concave hole. The top of the universal ball 12 extends out of the middle part of the upper spherical concave hole, and its top surface is a plane and is fixedly connected to the horizontal fixing plate 20 through a plurality of bolts.

[0093] When this embodiment is in use, the moving fixing plate 10 can be on the first transverse moving plate 60. When it needs to move from the first transverse moving plate 60 to the second transverse moving plate 61, it is necessary to first move the first transverse moving plate 60 or the second transverse moving plate 61 so that the front and rear ends of the intermediate guide rail 55 correspond to and align with the corresponding first longitudinal guide rail 64 and the second longitudinal guide rail 65. Then, rotate the rotating handle 662 so that the end of the locking screw 661 extends out of the corresponding screw-through hole and clamps the first guide rail 51 or the second guide rail 53 between the corresponding inner side wall and the end face of the end of the locking screw 661, so that the first transverse moving plate 60 and the second transverse moving plate 61 are fixed. At this time, the moving fixing plate 10 can be moved from the first transverse moving plate 60 to the second transverse moving plate 61 to achieve position movement.

[0094] When the movable fixed plate 10 needs to be moved to the corresponding position of the first transverse movable plate 60 or fixed in the second transverse movable plate 61, it can be moved to the corresponding position of the first transverse movable plate 60 or the second transverse movable plate 61, and the corresponding first holding portion 686 can be manually pulled to pull the vertical positioning block 685 outward, and then the movable fixed plate 10 is moved to the corresponding position, and the first holding portion 686 is released. The elastic restoring force of the buffer spring 687 allows the vertical positioning block 685 to return to its original position, so that the protruding clamping portion 689 is inserted into the corresponding vertical clamping groove 181 to achieve positioning, and the positioning is convenient.

[0095] In this embodiment, the movable fixed plate 10 can move forward and backward, and it can move to the first transverse movable plate 60 or the second transverse movable plate 61. At the same time, it can push the first transverse movable plate 60 or the second transverse movable plate 61 left and right, so that the movable fixed plate 10 thereon can be moved left and right, that is, the shock-absorbing tower installed on the movable fixed plate 10 can be moved left and right to meet the processing movement needs. It is easy to move and there is no need to carry the shock-absorbing tower, which greatly reduces the difficulty of moving it.

[0096] During installation, the embodiment adopts the universal ball 12, so that the shock tower 100 can be rotated at various angles. The riser at the bottom outer side of the side plate to be cut can be facing the cutting tool, and the transverse clamping rod 24 here is pulled down to be clamped into the corresponding two rear clamping grooves 141. When clamping, the rear positioning column 16 is first lowered, and then, when the transverse clamping rod 24 is clamped into the two rear clamping grooves 141, it will move forward so that most of it is clamped into the two rear clamping grooves 141. At this time, the transverse clamping rod 24 is clamped into the two rear clamping grooves 141. The portion of the clamping rod 24 at the top end of the rear positioning column 16 is not above it, and the rear positioning column 16 is lifted by the elastic restoring force of the spring 152, so that the front clamping slot 161 is behind the transverse clamping rod 24, so that the transverse clamping rod 24 is clamped at the front clamping slot 161 and the rear clamping slot 141 to achieve connection. In this embodiment, since the cutting riser does not need to be 100% removed, it only needs to ensure that 80% to 90% of the cutting is completed. Therefore, there will be a small deviation or error when it is clamped, but it will not affect subsequent processing.

[0097] A method for cutting the risers on the four sides of a shock tower using the above device comprises the following steps:

[0098] (1) Install the shock absorbing tower 100 to be processed onto the clamping device;

[0099] (2) Press down the first transverse clamping rod 201 at the rear side wall of the clamping device corresponding to the shock absorbing tower 100 to be processed, and clamp it into the two rear clamping grooves 141 and the one front clamping groove 161 to achieve clamping.

[0100] (3) Move the movable fixing plate 10 of the clamping device to the second transverse moving plate 61, and engage it into the corresponding vertical slot 181 formed on the right side wall of the positioning connection block 18 through the protruding clamping portion 689 of the vertical positioning block 685, so that the right part of the rear side wall of the shock tower 100 corresponds to the saw blade 70 to achieve fixation (in this embodiment, a plurality of positioning connection blocks 18 are fixed at the right side edge of the movable fixing plate 10, and a plurality of waist-shaped through holes are formed thereon. The screw portion of the bolt is inserted into the waist-shaped through hole and screwed onto the movable fixing plate 10. It can loosen the bolt as needed and slightly move the positioning connection block 18 back and forth, so as to change the position of the vertical slot 181 thereon to ensure that its position conforms to the position where the protruding clamping portion 689 is clamped and positioned, and its adjustment is convenient);
