Description

Technical Field

[0001] This utility model relates to the field of bearing ring parts manufacturing technology, and more specifically, to an assembled contour support tooling. Background Technology

[0002] Bearing ring blanks need to be heat-formed in a horizontal position. The company's existing heat-forming equipment is only equipped with standard V-shaped fixtures to support the bearing ring blanks. Currently, it has been found that while standard V-shaped fixtures are best suited for bearing ring blanks with the same outer diameter, they are less suitable for situations like... Figure 4 When using similar variable diameter bearing ring blanks, there is a problem of unstable support. The characteristic of this type of variable diameter bearing ring blank is that the outer diameter of the bearing ring has multiple variable diameter sections. When the variable diameter bearing ring blank is placed on a conventional V-shaped tooling seat, it is easy to tip over. This results in a scrap rate of about 3% of the bearing ring blanks due to scratches during the hot forming process (scratches are caused by the blank falling over and the outer diameter being scratched). In order to improve the product qualification rate, the company considered designing a transfer tooling to meet production needs, and this case came about. Utility Model Content

[0003] The purpose of this utility model is to address the needs of the prior art and provide an assembled contour support fixture. This utility model designs a contour seat to adapt to the shape of the bearing ring blank, so that the bearing ring blank can be stably supported laterally. The fixture frame of this utility model adopts an assembled installation design, and the two fixture seats can be folded or expanded to accommodate contour seats of different specifications on the top of the fixture frame.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An assembled contouring support fixture includes a contouring base and a fixture frame. The contouring base is a semi-circular base with a contouring groove in the center of its top. The fixture frame includes two symmetrically installed fixture bases. A clamping space is formed on the top of the two fixture bases. The lower part of the contouring base is adapted to be inserted into the clamping space. The contouring base is clamped and fixed by the opposite movement of the two fixture bases.

[0006] Furthermore, the tooling base includes a vertical plate and a base plate. The vertical plate is erected vertically, and the base plate is fixedly connected to the bottom side of the vertical plate. The base plate has bolt holes, and the top of the vertical plate has a notch. The two vertical plates are arranged with the notches facing each other, and a clamping space is formed between the two notches.

[0007] Furthermore, the two tooling seats are equipped with expansion and contraction guide elements, each comprising two parallel guide shafts. The guide shafts are transverse and adapted to be inserted into the vertical plates of the two tooling seats, and limit plates are fixedly connected to both ends of the guide shafts.

[0008] Furthermore, locking elements are installed on the two tooling seats, and the two tooling seats are locked in place by the locking elements. Two sets of locking elements are installed, and the two sets of locking elements are symmetrically installed at the upper and lower ends of the vertical plate, respectively.

[0009] Furthermore, the locking element includes a nut seat and a locking screw. The nut seat is fixedly connected to the outer wall of one of the vertical plates, and the locking screw is installed through both vertical plates and threadedly connected to the nut seat.

[0010] Furthermore, a limiting head is connected to one end of the locking screw. The diameter of the limiting head is larger than the diameter of the screw's through hole, and an assist plate is fixedly connected to the limiting head.

[0011] Furthermore, a set of positioning pins is connected to each of the two sides of the contour base in the width direction, and a set of positioning holes is opened on the top of each vertical plate. The contour base is positioned and installed in the clamping space by the fitting and insertion of the positioning pins and positioning holes.

[0012] The beneficial effects of this utility model are:

[0013] This utility model is designed with a contouring seat to adapt to the shape of the bearing ring blank, so that the bearing ring blank can be stably supported laterally. The tooling frame of this utility model adopts an assembly installation design. The two tooling seats can be folded or expanded to accommodate contouring seats of different specifications on the top of the tooling frame. By clamping contouring seats of different specifications, this utility model can meet the production support needs of multi-specification variable diameter bearing ring blanks.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 4 This is a type of variable diameter bearing ring blank. The characteristic of this type of variable diameter bearing ring blank is that the outer diameter of the bearing ring has multiple variable diameter sections. When placed on a conventional V-shaped tooling base, the variable diameter bearing ring blank is prone to tipping over. This leads to a relatively high rate of defective blanks (approximately 3%) during the hot forming process due to scoring. To change this production situation, such as... Figure 1-3 As shown, our company has researched and designed an assembled contour support fixture to meet production needs. It includes a contour base 1 and a fixture frame 2. The contour base 1 is a semi-circular base with a contour groove 11 at the center of its top. The size of the contour groove 11 is adapted to the size of the variable diameter bearing ring blank it needs to support. The variable diameter bearing ring blank can be stably placed horizontally within the contour groove 11 (referred to as a contour support). The fixture frame 2 is used to fix the contour base 1. The fixture frame 2 includes two symmetrically installed fixture seats 22 with a gap between them. A clamping space 21 is formed on the top of the two fixture seats 22. The lower part of the contour base 1 is adapted to be inserted into the clamping space 21. The fixture frame 2 adopts an assembled installation design, and the two fixtures are connected by a tooling... The two tooling seats 22 can move away from each other or towards each other. After the two tooling seats 22 move away from each other, the gap between the two tooling seats 22 increases, allowing the insertion of the copying seat 1. The movement of the two tooling seats 22 towards each other reduces the gap between the two tooling seats 22 until the copying seat 1 is clamped and fixed. After the copying seat 1 is clamped and fixed, the entire support tooling is formed. Copying seats 1 of different widths can be installed on the top of the tooling frame 2. This design is to meet the production support needs of multi-specification variable diameter bearing ring blanks (the copying seat 1 needs to be adapted to the variable diameter bearing ring blank. The dimensions of the copying seat 1 for different specifications of variable diameter bearing ring blanks vary (basically the width varies), so the tooling frame 2 needs to be adapted).

[0021] like Figure 1 and Figure 2As shown, the tooling base 22 includes a vertical plate 221 and a base plate 222. The vertical plate 221 is erected, and the base plate 222 is fixedly connected to the bottom side of the vertical plate 221 by welding. The base plate 222 has bolt holes for mounting bolts. In use, the contouring base 1 and the tooling frame 2 are assembled first, and then the entire tooling is fixed to the hot forming equipment with bolts. The top of the vertical plate 221 has a notch 223. The notch 223 is arc-shaped and adopts a semi-open mode in the width direction. The notch 223 is adapted to the shape of the contouring base 1. The two vertical plates 221 are set opposite each other with the notches 223. A clamping space 21 is formed between the two notches 223. The clamping space 21 is adapted to the insertion of the contouring base 1. When the contouring base 1 is inserted, its top surface needs to be level. Therefore, as follows Figure 3 As shown, this utility model has a set of positioning pins 12 connected to two sides of the contour base 1 in the width direction. Each vertical plate 221 has a set of positioning holes 224 on its top. The set of positioning pins 12 is installed in accordance with the set of positioning holes 224. When the contour base 1 is installed, the positioning pins 12 are aligned with the positioning holes 224. The contour base 1 is positioned and installed in the clamping space 21 by the matching insertion of the positioning pins 12 and the positioning holes 224. The top surface of the contour base 1 is horizontal, which ensures the stable support of the variable diameter bearing ring blank and does not affect the hot forming operation.

[0022] In order to ensure that the two tooling seats 22 can be assembled smoothly, such as Figure 1 and Figure 2 As shown, this utility model designs and installs expansion and contraction guide elements 23 on two tooling seats 22. The expansion and contraction guide elements 23 include two parallel guide shafts 231. The guide shafts 231 are transverse and adapted to be installed on the vertical plates 221 of the two tooling seats 22. After the guide shafts 231 are installed, the two tooling seats 22 can only slide along the length direction of the guide shafts 231, ensuring that the two tooling seats 22 can move accurately away from each other or towards each other. The two ends of the guide shafts 231 are respectively fixedly connected to limit plates 232. The diameter of the limit plates 232 is larger than that of the guide shafts 231, which plays the role of end limit. The length of the guide shafts 231 is the maximum expansion and separation length of the two tooling seats 22, which determines the maximum width of the contour seat 1 that can be installed in the clamping space 21.

[0023] After the contour base 1 is installed, the two tooling seats 22 also need to be locked so that they can clamp the contour base 1 and form a complete support fixture. Therefore, as follows... Figure 1 and Figure 2As shown, locking elements 24 are installed on the two tooling seats 22 of this utility model. The two tooling seats 22 are locked and formed by the locking elements 24. Two sets of locking elements 24 are installed, and the two sets of locking elements 24 are symmetrically installed at the upper and lower ends of the vertical plate 221. The design of the two sets of locking elements 24 is to make the entire support tooling more stable and reliable. The locking element 24 includes a nut seat 241 and a locking screw 242. The nut seat 241 is fixedly connected to the outer wall of one of the vertical plates 221 (welded fixed). The locking screw 242 is installed from the other vertical plate 221 side. The locking screw 242 passes through the two vertical plates 221 and then... The screw is threaded to the nut seat 241. One end of the locking screw 242 is connected to a limiting head 243. The diameter of the limiting head 243 is larger than the diameter of the screw through hole. As the locking screw 242 is screwed in, the limiting head 243 pushes one tool seat 22 forward to another tool seat 22 until the upper contour seat 1 is clamped. An assist plate 244 is fixedly connected to the limiting head 243. The locking screw 242 can be easily rotated through the assist plate 244. When using a large-width contour seat 1, a long-length locking screw 242 should also be selected. During the assembly of this utility model, the two sets of locking elements 24 are rotated alternately until the contour seat 1 is clamped and fixed.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
