Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and more specifically to a device for heat treatment of stabilizer bars. Background Technology

[0002] A stabilizer bar, also known as an anti-roll bar or balance bar, is an auxiliary elastic element in a car's suspension. When a car turns, the body tilts, and the two sides of the suspension bounce unevenly. The outer suspension presses against the stabilizer bar, causing it to twist. The elasticity of the bar prevents the wheels from lifting off the ground, thus keeping the car body as balanced as possible and providing lateral stability.

[0003] like Figure 1 As shown, the stabilizer bar 100 has a roughly U-shaped structure, including a bar body 101 and connecting portions 102 at both ends of the bar body 101. The connecting portions 102 are used to connect to the vehicle's suspension. The shape and specifications of the stabilizer bar 100 vary depending on the vehicle model. In actual production, the connecting portions 102 at both ends of the stabilizer bar 100 need to be heated and then press-fitted with punches. However, due to the differences in the shape and specifications of the stabilizer bar, various tooling equipment for heat treatment of the stabilizer bar needs to be designed and manufactured. The types of tooling equipment correspond one-to-one with the specifications of the stabilizer bar, which increases production input and reduces production flexibility. Summary of the Invention

The second holding assembly includes a driving member, a push rod mounted on the driving member, and a movable member disposed at the end of the push rod. The second holding assembly also includes a fixing member opposite to the movable member. The driving member is a cylinder gripper, and the sliding finger of the cylinder gripper is connected to the end of the push rod.

[0006] Furthermore, the second support assembly also includes a frame, within which a stabilizing structure is provided, the stabilizing structure being a triangular plate disposed at one corner of the frame, and the fasteners being disposed at both ends of the frame.

[0007] Furthermore, a limiting sleeve is provided on the frame, and the limiting sleeve is fitted onto the push rod, the inner diameter of the limiting sleeve being the same as the outer diameter of the push rod.

[0008] Furthermore, the movable component has an inverted L-shaped structure, and a clamping part is provided on the side of the movable component near the fixed component.

[0009] Furthermore, the upper end surface of the fixing member is a support surface for placing the stabilizing rod, and a fixing part is provided on the side of the support surface away from the movable member, the fixing part being able to cooperate with the support part to fix the stabilizing rod.

[0010] Furthermore, the column has a first mounting surface and a second mounting surface. The first mounting surface has a first mounting groove for mounting a first support component, and the second mounting surface has a second mounting groove for mounting a second support component.

[0011] Furthermore, the first mounting groove and the second mounting groove are provided in multiple ways along the axial direction of the column.

[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this invention clearer, the invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic structure of the invention, and therefore only shows the components relevant to the invention. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] refer to Figure 2-8 As shown, the present invention provides an apparatus for heat treatment of stabilizer bars, comprising a fixing mechanism 10 adaptable to stabilizer bars 100 of various specifications and a heating mechanism 20 disposed beside the fixing mechanism 10. The fixing mechanism 10 is used to hold the stabilizer bar 100, and the heating mechanism 20 heats the connecting portion 102 of the stabilizer bar 100 on the fixing mechanism 10. In some embodiments, two heating mechanisms 20 are provided, respectively located on both sides of the fixing mechanism 10, so as to simultaneously heat the connecting portions 102 at both ends of the stabilizer bar 100.

[0029] Combination Figure 3 and Figure 4As shown, the fixing mechanism 10 includes a column 11, a first support assembly 12 disposed on the top of the column 11, and a second support assembly 13 disposed on the column 11. The column 11 has a first mounting surface 111 for mounting the first support assembly 12 and a second mounting surface 113 for mounting the second support assembly 13, the first mounting surface 111 and the second mounting surface 113 being perpendicular to each other. The first mounting surface 111 is provided with a first mounting groove 112 for mounting the first support assembly 12, and the second mounting surface 113 is provided with a second mounting groove 114 for mounting the second support assembly 13.

[0030] In some embodiments, a plurality of first mounting grooves 112 and second mounting grooves 114 are provided along the axial direction of the column 11.

[0031] Combination Figure 5 As shown, the first support assembly 12 includes a connector 121 installed in the first mounting groove 112 and a support member 122 installed at the end of the connector 121 away from the column 11. The support member 122 has a support groove 123, in which the rod body 101 of the stabilizer bar 100 can be placed. In this embodiment, the support groove 123 is a square groove, and the size of the support groove 123 is larger than the size of the rod body 101 of the stabilizer bar 100, thereby allowing for the placement of stabilizer bars 100 of various sizes.

[0032] In some embodiments, in order to ensure that the pole body 101 of the stabilizer bar 100 can be stably supported, two first support components 12 are provided, and the two first support components 12 are arranged opposite to each other on the column 11.

[0033] In this embodiment, the connector 121 is fixed in the first mounting groove 112 by bolts. In other embodiments, the connector 121 can also be installed in the first mounting groove 112 by welding, riveting or snap-fitting.

[0034] Combination Figure 5 As shown, in some embodiments, the lower edge of the connector 121 is provided with a support portion 1211 protruding along the direction of the support member 122. The support member 122 is provided with a support groove 1221 corresponding to the support portion 1211. The end face of the support portion 1211 abuts against the groove surface of the support groove 1221, thereby allowing the connector 121 to bear the weight of the support member 122 and the stabilizer 100 through the support portion 1211, preventing the weight of the support member 122 and the stabilizer 100 from being entirely borne by the connection structure between the connector 121 and the support member 122. In this embodiment, the connector 121 and the support member 122 are connected by bolts. In other embodiments, the connector 121 and the support member 122 can also be connected by welding or riveting.

[0035] The second support assembly 13 includes a frame 131 mounted on the column 11, fixing members 132 disposed at both ends of the frame 131, and a drive member 133 disposed on the frame 131. A push rod 134 is provided at the output end of the drive member 133, and a movable member 135 is provided at the end of the push rod 134 away from the drive member 133. The drive member 133 can move the movable member 135 closer to or further away from the fixing member 132 via the push rod 134. The fixing members 132 and the movable member 135 can support the stabilizer bar 100 between its body 101 and connecting portion 102, thereby cooperating with the first support assembly 12 to form at least a three-point support structure for placing the stabilizer bar 100. Furthermore, since the distance between the fixing member 132 and the movable member 135 is adjustable, it can accommodate various sizes of stabilizer bars 100.

[0036] In some embodiments, a stabilizing structure 1311 is provided within the frame 131 to ensure the stability of the frame 131. In this embodiment, the stabilizing structure 1311 is a triangular plate disposed at one corner of the frame 131. One side of the frame 131 is bolted into the second mounting groove 114. In other embodiments, the frame 131 can also be mounted into the second mounting groove 114 by welding, riveting, or snap-fitting.

[0037] In this embodiment, the drive component 133 is installed on the side of the frame 131 away from the column 11, and the drive component 133 is a cylinder gripper. The sliding finger of the cylinder gripper is fixedly connected to one end of the push rod 134. When the cylinder gripper opens, the sliding finger of the cylinder gripper pushes the movable component 135 towards the fixed component 132 via the push rod 134; when the cylinder gripper clamps, the sliding finger of the cylinder gripper causes the movable component 135 to move away from the fixed component 132 via the push rod 134. It is understood that in some other embodiments, the drive component 133 can also be a cylinder, a hydraulic cylinder, a guide rail, or other structures or devices capable of generating linear drive.

[0038] In some embodiments, a limiting sleeve 136 is also provided on the frame 131, and the limiting sleeve 136 is fitted onto the push rod 134. The inner diameter of the limiting sleeve 136 is the same as the outer diameter of the push rod 134, ensuring that the push rod 134 can always maintain directional movement and increasing the stability of the push rod 134 during movement. In this embodiment, the limiting sleeve 136 is a guide bearing.

[0039] Combination Figure 6As shown, in this embodiment, the movable member 135 is generally inverted L-shaped, and a clamping part 1351 is provided on the side of the movable member 135 near the fixed member 132. The upper end surface of the fixed member 132 is a support surface 1321 for placing the stabilizer bar 100, and a fixing part 1322 protrudes from the side of the support surface 1321 away from the movable member 135. Under the pushing action of the push rod 134, the movable member 135 can clamp the stabilizer bar 100 placed on the support surface 1321.

[0040] refer to Figure 7 and Figure 8 As shown, the heating mechanism 20 includes a base 21, a support rod 22 mounted on the base 21, and an angle adjustment assembly 23 disposed on the support rod 22. A guide rail 24 is disposed on the angle adjustment assembly 23, and a heating coil 25 electrically connected to a high-frequency device (not shown) via a wire is disposed at the output end of the guide rail 24. The angle adjustment assembly 23 can move along the axial direction of the support rod 22, adjusting the tilt angle of the guide rail 24 so that the axis of the heating coil 25 is collinear with the axis of the connecting portion 102 of the stabilizer rod 100, thereby allowing the guide rail 24 to drive the heating coil 25 to be fitted onto the connecting portion 102 of the stabilizer rod 100. The high-frequency device electrically drives the heating coil 25, heating the connecting portion 102 of the stabilizer rod 100 to a set temperature at a set power. The heated stabilizer rod 100 is then transported by a transfer device to a stamping device for pressing and punching.

[0041] In some embodiments, a limiting member 221 for limiting the height of the angle adjustment assembly 23 is provided on the support rod 22, and the limiting member 221 is fixed to the support rod 22 by bolts. The upper end face of the limiting member 221 abuts against the angle adjustment assembly 23 to prevent the angle adjustment assembly 23 from moving downward along the axial direction of the support rod 22.

[0042] refer to Figure 8 As shown, the angle adjustment assembly 23 includes a first adjustment block 231 and a second adjustment block 232 opposite to the first adjustment block 231. The first adjustment block 231 has a receiving groove 2311 for accommodating the support rod 22, the groove surface of which fits against the side wall of the support rod 22. A bolt hole 2312 is provided at the end of the first adjustment block 231 away from the guide rail 24, the axis of which is perpendicular to the axis of the support rod 22. A supporting portion 2313 is provided at the end of the first adjustment block 231 near the guide rail 24, protruding radially outward along the end face of the first adjustment block 231.

[0043] The second adjusting block 232 has the same structure as the first adjusting block 231. The second adjusting block 232 can be connected to the first adjusting block 231 by a bolt inserted into the bolt hole 2312.

[0044] The angle adjustment assembly 23 also includes a support member 233 disposed on the side of the guide rail 24 away from the heating coil 25. A limiting portion 2331 protruding radially inward along the end face of the support member 233 away from the guide rail 24 is provided. In some embodiments, the support member 233 is generally annular in structure, and the support member 233 is connected to the guide rail 24 by welding.

[0045] Combination Figure 8 As shown, the supporting portions 2313 of the first adjusting block 231 and the second adjusting block 232 are both located within the supporting member 233. During the tightening of the bolts connecting the first adjusting block 231 and the second adjusting block 232, a lever structure is formed between the first adjusting block 231, the second adjusting block 232 and the support rod 22. The bolt holes 2312 of the first adjusting block 231 and the second adjusting block 232 approach each other during bolt tightening. The support rod 22 between the first adjusting block 231 and the second adjusting block 232 acts as a fulcrum, causing the supporting portions 2313 of the first adjusting block 231 and the second adjusting block 232 to move away from each other. The circumferential sidewall of the supporting portion 2313 abuts against the inner wall of the supporting member 233, generating a frictional torque to resist the gravitational torque of the guide rail 24 and prevent the guide rail 24 from rotating. The end face of the supporting part 2313 near the support rod 22 can abut against the end face of the limiting part 2331 near the slide rail, preventing the guide rail 24 from falling off the first adjusting block 231 and the second adjusting block 232.

[0046] It is understood that in some other embodiments, the angle adjustment component 23 may also be a motor or a rotary cylinder.

[0047] In this embodiment, the circumferential outer wall of the abutment member 233 can abut against the upper end surface of the limiting member 221 to prevent the angle adjustment assembly 23 and the guide rail 24 from sliding off along the axial direction of the support rod 22.

[0048] The compatibility tooling for heat treatment of stabilizer bar 100 provided by this invention is used as follows: When the stabilizer bar 100 to be processed is changed from one specification to another, the size of the stabilizer bar 100 and the bending direction of the connecting part 102 both change. Technicians adjust the drive component 133 to cause the push rod 134 to move the movable part 135 closer to or further away from the fixed part 132, so that the distance between the movable part 135 and the fixed part 132 is adapted to the size of the stabilizer bar 100 after the specification change. The bar body 101 of the stabilizer bar 100 is placed in the support groove 123, and the portion between the bar body 101 and the connecting part 102 is placed on the support surface 1321 of the fixed part 132. The clamping part 1351 of the movable part 135 and the fixing part 1322 of the fixed part 132 further limit the stabilizer bar 100, ensuring that the stabilizer bar 100 is stably placed on the fixing mechanism 10. Technicians then adjust the height of the angle adjustment component 23 and the tilt angle of the guide rail 24 to make the axis of the heating coil 25 and the axis of the connecting part 102 of the stabilizer 100 collinear. This ensures that the guide rail 24 can drive the heating coil 25 to be fitted onto the connecting part 102 of the stabilizer 100, thereby enabling the tooling to be adapted to various specifications of stabilizer 100, with extremely high compatibility, thus reducing production input and increasing production flexibility.
