[0018] The working principle and beneficial effects of the present utility model are as follows:

[0019] In the present utility model, first, the detachable base design of the quenching positioning tooling facilitates the rapid replacement and maintenance of the tooling, reduces the equipment downtime. At the same time, the rapid and accurate positioning can shorten the clamping time of the workpiece, thereby improving the efficiency of the entire production process. For example, in large-scale production, more batches of workpieces can be processed every day, effectively increasing the output. Specifically, the detachable form can adopt bolt connection, snap connection, pin connection, magnetic attraction connection, dovetail groove connection, etc.; screw holes can be correspondingly provided on the base and the bottom plate, and bolts are used to pass through the screw holes to fix the base on the bottom plate, this method is simple and reliable, and is convenient for installation and disassembly; magnets with opposite magnetic poles can be respectively installed on the base and the bottom plate, and the detachable connection is realized by magnetic attraction, and at the same time, forms such as dovetail grooves convenient for guiding and positioning are equipped to achieve rapid connection.

[0020] Furthermore, to ensure the uniformity of workpiece quenching, especially for the quenching requirements of the inner wall of the square hole cavity of sleeve-shaped workpieces, and to facilitate the adjustment of the placement direction and tilt angle of sleeve-shaped workpieces on the surface quenching tooling, a rotary table is rotatably arranged on the inclined surface of the base, enabling the workpiece to be heated more uniformly during the quenching process, avoiding local overheating or overcooling, thus significantly improving the quenching quality. At the same time, since many of the directions of the inner wall of the square hole cavity have a certain angle with the vertical direction, during quenching, the main shaft equipped with the quenching inductor needs to be inserted into the square hole cavity, and the axis of the main shaft should be parallel to the quenching surface for quenching. There are two quenching surfaces. When quenching different quenching surfaces, it is necessary to twist the placement direction and tilt angle of the workpiece on the tooling. Therefore, the rotary table can drive several positioning blocks on it to rotate, enabling the rapid adjustment of the position and angle of the sleeve-shaped workpiece clamped in the workpiece positioning area, eliminating the need to completely disassemble the traditional quenching positioning tooling, which is very troublesome. Moreover, the use of the inclined surface is also to cooperate with the direction of the inner wall of the square hole cavity, facilitating the parallel quenching of the main shaft of the quenching inductor with the inner wall quenching surface.

[0021] In addition, the use of the workpiece positioning area composed of several positioning blocks can be flexibly adjusted to accommodate workpieces of various shapes and sizes. For example, for square, triangular, or irregularly shaped workpieces, stable positioning can be achieved by adjusting the position and spacing of the positioning blocks, meeting diverse production requirements, not limited to sleeve-shaped workpieces. It mainly solves the quenching problem of sleeve-shaped workpieces through rotation and the inclined surface. This device also has the characteristics of reducing labor intensity, saving energy, and being easy to achieve automated production, further improving production efficiency and quality control level.

[0022] In the specific actual production process, it is found that in addition to sleeve-shaped workpieces, there is also a kind of dynamic shaft workpiece that is processed more. The design of this quenching positioning tooling also meets the universality between the two, saves the auxiliary time for tool change, greatly reduces the failure rate, and the wearing parts can also be processed at any time, being safe and reliable.

[0032] In this article, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0034] Refer to Figures 1 to 5, which is the first embodiment of the present utility model, provides a positioning tooling for quenching, including: a bottom plate 1 and a base 2, the base 2 is detachably arranged on the bottom plate 1, and the base 2 has an inclined surface 201; a rotary table 3, the rotary table 3 is rotatably arranged on the inclined surface 201, the rotary table 3 has a shaft portion 301, and the axis of the shaft portion 301 is perpendicular to the inclined surface 201; a plurality of positioning blocks 4, the plurality of positioning blocks 4 are all arranged on the rotary table 3, and a workpiece positioning area 5 is formed between the plurality of positioning blocks 4.

[0035] In this embodiment, as Figures 1 to 5 shown, first of all, the detachable design of the base 2 of the quenching positioning tooling facilitates the rapid replacement and maintenance of the tooling, reduces the equipment downtime. At the same time, the rapid and accurate positioning can shorten the clamping time of the workpiece, thereby improving the efficiency of the entire production process. For example, in large-scale production, more batches of workpieces can be processed every day, effectively increasing the output. Specifically, the detachable form can adopt bolt connection, snap connection, pin connection, magnetic attraction connection, and dovetail groove connection, etc.; screw holes can be correspondingly arranged on the base 2 and the bottom plate 1, and bolts are used to pass through the screw holes to fix the base 2 on the bottom plate 1. This method is simple and reliable, and is convenient for installation and disassembly; magnets with opposite magnetic poles can be installed on the base 2 and the bottom plate 1 respectively, and the detachable connection is realized by magnetic attraction. At the same time, forms such as dovetail grooves for facilitating guiding and positioning are equipped to achieve rapid connection.

[0036] Furthermore, to ensure the uniformity of quenching of the workpiece, especially for the quenching requirements of the inner wall of the square hole cavity of sleeve-shaped workpieces, and to facilitate the adjustment of the placement direction and inclination angle of the sleeve-shaped workpiece on the surface quenching tooling, a rotary table 3 is rotatably arranged on the inclined surface 201 of the base 2, so that the workpiece can be heated more evenly during the quenching process, avoiding local overheating or overcooling, thereby significantly improving the quenching quality. At the same time, since many directions of the inner wall of the square hole cavity have a certain angle with the vertical direction, during quenching, the main shaft equipped with a quenching inductor needs to be inserted into the square hole cavity, and the axis of the main shaft is parallel to the quenching surface for quenching. There are two quenching surfaces. When quenching different quenching surfaces, it is necessary to twist the placement direction and inclination angle of the workpiece on the tooling. Therefore, the rotary table 3 can drive a plurality of positioning blocks 4 thereon to rotate, so that the position and angle of the sleeve-shaped workpiece clamped in the workpiece positioning area 5 can be quickly adjusted, without the need to completely disassemble the whole tooling like the traditional quenching positioning tooling, which is very troublesome; and the use of the inclined surface 201 is also to cooperate with the direction of the inner wall of the square hole cavity, facilitating the parallel quenching of the main shaft of the quenching inductor and the inner wall quenching surface.

[0037] In addition, the use of the workpiece positioning area 5 composed of several positioning blocks 4 can be flexibly adjusted to accommodate workpieces of various shapes and sizes. For example, for square, triangular, or irregularly shaped workpieces, stable positioning can be achieved by adjusting the position and spacing of the positioning blocks 4, meeting diverse production requirements. It is not limited to sleeve workpieces only. The quenching problem of sleeve workpieces is mainly solved through rotation and the inclined surface 201. This device also has the characteristics of reducing labor intensity, saving energy, and being easy to automate production, further improving production efficiency and quality control level.

[0038] In the specific actual production process, it is found that in addition to sleeve workpieces, there is also a kind of rotating shaft workpiece that is processed more. The design of this quenching positioning tooling also meets the generality between the two, saves the auxiliary time for tool change, greatly reduces the failure rate, and the wearing parts can also be processed at any time, being safe and reliable.

[0039] Furthermore, the top of the base 2 has a support platform 202. The cross-section of the support platform 202 is circular, and the top of the support platform 202 has an inclined surface 201.

[0040] Furthermore, the turntable 3 is cylindrical. The center of the bottom of the turntable 3 has a rotating shaft portion 301, and the turntable 3 and the base 2 are coaxially arranged.

[0041] In this embodiment, as Figures 1 to 5 shown, specifically for the quenching means of sleeve workpieces, the inclined surface 201 and the turntable 3 are further defined to make the entire positioning tooling operate more stably and improve production safety. The circular support platform 202 at the top of the base 2 provides a stable support foundation for the turntable 3, and the inclined surface 201 is set on its top, which can effectively disperse the pressure and impact force from the cylindrical turntable 3, ensuring that the tooling will not deform or be damaged due to uneven stress during quenching. At the same time, there will be no hard and sharp parts during their operation to hurt the operators. Moreover, the inclined surface 201 can also better guide heat and transfer the flowing coolant, thereby improving the efficiency and quality of quenching.

[0042] This structural design reduces the shaking and deviation during rotation, improving the accuracy and stability of rotation. When quenching workpieces with high precision requirements, it can ensure that each part of the workpiece can be quenched according to the predetermined process requirements, thus guaranteeing the consistency and reliability of the product.

[0043] Furthermore, the center position of the support platform 202 has a support hole 203. The rotating shaft portion 301 passes through the support hole 203. The support hole 203 has a stepped groove 204. It also includes: an installation ring 6. The installation ring 6 is disposed through the rotating shaft portion 301, and the installation ring 6 is in interference fit with the stepped groove 204.

[0044] In this embodiment, Figures 1 to 5 As shown, in order to facilitate the rapid assembly of the quenching positioning tooling, the turntable 3 is set on the support table 202 welded on the base 2. On the one hand, the support hole 203 of the support table 202 is used to stably support and limit the rotation axis portion 301 at the bottom center of the turntable 3. On the other hand, a stepped groove 204 is opened on the support hole 203, and a truncated cone-shaped mounting ring 6 is passed through the rotation axis portion 301. During the assembly and installation process, the positions of the base 2 and the turntable 3 can be quickly matched. Finally, the interference fit also ensures the stability of the connection between the two, thereby ensuring the rotation accuracy of the turntable 3.

[0045] Furthermore, the inclined surface 201 has a plurality of positioning holes 205, and the plurality of positioning holes 205 are arranged along the circumference of the rotating shaft portion 301. The turntable 3 has a positioning hole 202. After the turntable 3 rotates, the positioning hole 202 is connected to or disconnected from one of the positioning holes 205. The turntable 3 also includes: a positioning locking member 7, which is used to penetrate the positioning hole 205 and the positioning hole 202, and is used to limit the rotation of the turntable 3.

[0046] Furthermore, a positioning portion 401 is provided on the top of the positioning block 4 , and a plurality of positioning blocks 4 are arranged along the circumference of the turntable 3 .

[0047] Furthermore, the base 2 is detachably arranged on the bottom plate 1 by means of fasteners.

[0048] In this embodiment, Figures 1 to 5 As shown, in order to further determine the rotation angle of the turntable 3 relative to the base 2, it is convenient for rapid positioning after adjusting the position and angle, and a pin connection is adopted. Through the cooperation of the positioning hole 1 205, the positioning hole 2 302 and the positioning locking member 7, during the quenching process, the turntable 3 can be adjusted to the most suitable angle and kept stable according to the specific needs of the workpiece. For example, for a workpiece with a specific structure or shape, it can ensure that the part that needs to be quenched is accurately in the best heating and cooling position.

[0049] And because the turntable 3 itself has high rotation flexibility, several positioning holes 205 are arranged in a circle to adapt to the quenching surface angles of different workpieces, so as to more precisely control the quenching process of the workpiece. The positioning locking member 7 is a pin body, which limits the rotation of the turntable 3; the positioning portion 401 at the top of the positioning block 4 can better limit the workpiece from its bottom, rather than just clamping it in the workpiece positioning area 5.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
