[0030] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] like Figures 1 to 3 As shown, this utility model provides a positioning device, including a bracket 100, a limiting block 101, a positioning pin 200, a pressure arm 201 assembly, and a lifting assembly;

[0034] One end of the bracket 100 is located on the fixed surface, and the other end is provided with a limiting block 101. The top wall of the limiting block 101 and the top wall of the bracket 100 are parallel to each other.

[0035] The pressure arm 201 assembly is rotatably connected to the end of the bracket 100 away from the fixed surface. The pressure arm 201 assembly is in contact with or away from the limiting block 101. The limiting block 101 is used to limit the extreme position of the pressure arm 201 assembly.

[0036] One end of the lifting assembly is fixedly connected to the bracket 100, and the other end is connected to one end of the pressure arm 201 assembly. The lifting assembly can drive the pressure arm 201 assembly to rotate along its own axis. The positioning pin 200 is located at the end of the pressure arm 201 assembly away from the lifting assembly.

[0037] In this embodiment, the positioning device includes a bracket 100, a limiting block 101, a positioning pin 200, a pressure arm 201 assembly, and a lifting assembly. The limiting block 101, positioned above the bracket 100, has its top wall parallel to the top wall of the bracket 100, thus limiting the extreme position of the pressure arm 201 assembly during rotation. The lifting assembly can then lift the pressure arm 201 assembly to fit against the limiting block 101, maintaining a horizontal position. Simultaneously, the positioning pin 200 at the end of the pressure arm 201 assembly can fix the component to be fixed, achieving clamping and positioning. Correspondingly, the lifting assembly can also drive the pressure arm 201 assembly to rotate to one side, simultaneously lifting the positioning pin 200 to release the clamped component. This allows for direct pressure positioning of the component to facilitate subsequent welding processes. The entire process is clear in principle, simple to operate, and effectively ensures operational efficiency.

[0038] Of course, the fixed surface refers to the workbench, the ground or other flat surfaces in the workshop, as long as they are level. In conjunction with the positioning pin 200, there is also a fixing pin 400. The fixing pin 400 is placed directly below the positioning pin 200. For example, pipe-type parts can be directly inserted into the positioning pin 200, and then the positioning pin 200 can be inserted from above into the parts to be fixed to complete the fixing.

[0039] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the bracket 100 includes a column 102 and a base plate 103. The base plate 103 is disposed on the fixed surface. The bottom end of the column 102 is vertically disposed on the upper surface of the base plate 103. The top end of the column 102 is provided with a limiting block 101 and a pressure arm 201 assembly.

[0040] In this embodiment, the upper surfaces of the column 102 and the base plate 103 are vertically connected, which ensures that when the base plate 103 is placed on the fixed surface, the upper surface of the column 102 is perpendicular to the fixed surface. This ensures that the limiting block 101 at the top of the column 102 is parallel to its upper surface and thus parallel to the fixed surface, thereby restricting the pressure arm 201 assembly from directly pressing the fixed parts.

[0041] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the pressure arm 201 assembly includes a pressure arm 201. One end of the pressure arm 201 is provided with a positioning pin 200, and the other end is connected to the lifting assembly. The lifting assembly can drive the pressure arm 201 to rotate along its own axis.

[0042] In this embodiment, one end of the pressure arm 201 is provided with a positioning pin 200, and the other end is connected to the lifting assembly. The lifting assembly directly drives the pressure arm 201 to rotate along its own axis. That is, the lifting assembly can lift the pressure arm 201 to fit against the limiting block 101, thereby keeping it horizontal and achieving pressing and positioning. Correspondingly, the lifting assembly can also drive the pressure arm 201 to rotate to one side, thereby releasing the pressed parts.

[0043] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the pressure arm 201 is provided with a first rotating hole, and the top of the column 102 is provided with a first mounting groove. The pressure arm 201 is located in the first mounting groove. The two side walls of the first mounting groove are respectively provided with second rotating holes corresponding to the first rotating hole. The fixed positioning column 202 passes through the second rotating hole and the first rotating hole in sequence to connect the pressure arm 201 to the column 102.

[0044] In this embodiment, a first mounting groove for mounting the pressure arm 201 is provided at the top of the column 102. Correspondingly, a first rotating hole is provided in the pressure arm 201. Second rotating holes that cooperate with the first rotating hole are respectively provided on the two side walls of the first mounting groove. The pressure arm 201 is rotatably connected to the column 102 by passing the fixed positioning column 202 through the second rotating hole and the first rotating hole in sequence. That is, by fixing it in place, the pressure arm 201 can rotate circumferentially along its own axis along the fixed positioning column 202 under the drive of the lifting component. Preferably, the inner diameter of the first rotating hole and the second rotating hole is larger than the outer diameter of the fixed positioning column 202, so as to ensure that the pressure arm 201 can rotate smoothly.

[0045] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the pressure arm 201 assembly also includes a connecting frame 203, which is located at the end of the pressure arm 201 away from the positioning pin 200, and the bottom of the connecting frame 203 is connected to the lifting assembly.

[0046] In this embodiment, the pressure arm 201 assembly also includes a connecting frame 203 for connecting with the lifting assembly. The connecting frame 203 is located at the end of the pressure arm 201 away from the positioning pin 200. The pressure arm 201 and the lifting assembly are combined through the connecting frame 203 so that the lifting assembly can drive the pressure arm 201 to rotate to press or release the parts.

[0047] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the end of the pressure arm 201 away from the positioning pin 200 is provided with a waist-shaped sliding groove 204, the connecting frame 203 is provided with a second mounting groove 205, the end of the pressure arm 201 is provided in the second mounting groove 205, the two side walls of the second mounting groove 205 are respectively provided with connecting holes, the sliding positioning pin 206 passes through the connecting hole and the waist-shaped sliding groove 204 in sequence, and the sliding positioning pin 206 can slide along the extended square of the waist-shaped sliding groove 204.

[0048] In this embodiment, a second mounting groove 205 is provided in the connecting frame 203, and the end of the pressure arm 201 is located in the second mounting groove 205. Connection holes are respectively opened on both sides of the second mounting groove 205. The sliding positioning post 206 passes through the connection hole and the waist-shaped sliding groove 204 in sequence to connect the connecting frame 203 and the pressure arm 201. At the same time, the sliding positioning post 206 can slide along the extension square of the waist-shaped sliding groove 204, so that the pressure arm 201 can rotate smoothly.

[0049] According to one embodiment provided by this utility model, such as Figure 1 and Figure 3As shown, the sliding positioning post 206 has slots at both ends, and a limiting spring 207 is provided in the slot.

[0050] In this embodiment, the two ends of the sliding positioning post 206 protrude from the connecting frame 203, and slots are provided at both ends for installing snap rings 207. That is, the snap rings 207 set in the slots limit the movement and prevent the sliding positioning post 206 from coming out.

[0051] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the lifting assembly includes a pressing cylinder 300 and a cylinder base plate 301. The cylinder base plate 301 is fixed to the side wall of the column 102, and the pressing cylinder 300 is installed on the upper surface of the cylinder base plate 301. The output end of the pressing cylinder 300 is connected to the connecting frame 203.

[0052] In this embodiment, a cylinder base plate 301 is fixedly provided on the side wall of the column 102, and a pressing cylinder 300 is installed on the upper surface of the cylinder base plate 301. The output end of the pressing cylinder 300 is connected to the connecting frame 203. The pressing cylinder 300 drives the connecting frame 203 to move down, thereby driving the sliding positioning column 206 to slide in the waist-shaped sliding groove 204, so as to drive the pressing arm 201 to rotate.

[0053] According to one embodiment provided by this utility model, such as Figure 1 As shown, the bracket 100 also includes a support rib plate 104.

[0054] In this embodiment, since the base plate 103 and the column 102 are arranged perpendicularly to each other, a supporting rib 104 is provided between the side wall of the column 102 and the top wall of the base plate 103 to ensure the vertical support stability of the column 102. Optionally, one supporting rib 104 is provided. Of course, the specific number can be set according to actual usage requirements. No specific limitation is made here. The purpose is to deviate from the design concept of this utility model and should fall within the protection scope of this utility model.

[0055] According to one embodiment provided by this utility model, such as Figure 1 As shown, the upper top wall of the limiting block 101 is provided with a groove 105, and the pressure arm 201 can be inserted into or withdrawn from the groove 105.

[0056] In this embodiment, a protrusion corresponding to the position of the limiting block 101 is provided on the lower bottom wall of the pressure arm 201. Correspondingly, in order to cooperate with the protrusion, a groove 105 is provided on the upper top wall of the limiting block 101. During the rotation of the pressure arm 201, the protrusion is inserted into or withdrawn from the groove 105, thereby limiting the pressure arm 201 and further preventing the pressure arm 201 from swaying left and right.

[0057] In summary, the working principle of the positioning device provided in this embodiment is as follows: The clamping cylinder 300 is fixed to the side wall of the column 102 via the cylinder base plate 301. The output end of the clamping cylinder 300 is originally in the extended state, and the connecting frame 203 is also located away from the clamping cylinder 300. The sliding positioning pin 206 is located on the left side of the waist-shaped sliding groove 204 opened on the pressure arm 201. With the extension force of the clamping cylinder 300, the force is transmitted to the positioning pin 200 at the other end using the lever characteristic, thereby realizing the clamping and positioning of the parts. After use, the clamping cylinder 300 is clamped. The cylinder 300 begins to retract, causing the connecting frame 203 and the sliding positioning column 206 to move downwards, which in turn pulls the pressure arm 201 to rotate around the fixed positioning column 202. As the pressure arm 201 rotates, the sliding positioning column 206 moves downwards along the circumference of the pressing cylinder 300. The sliding positioning column 206 gradually slides to the right within the waist-shaped sliding groove 204. As the rotation angle of the pressure arm 201 exceeds the tangent point of the axis, the sliding positioning column 206 begins to return and slide to the left until the pressing cylinder 300 is fully retracted and the pressure arm 201 is fully opened, thus releasing the pressed parts.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
