Utility Model Content

[0005] The purpose of this utility model is to provide a shaft tooling fixture test box, which can solve the problems of large size of shaft tooling fixture test boxes and complicated and cumbersome steps for fixing shaft workpieces.

[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0007] A shaft-type tooling fixture test box includes: a box body and a base;

[0008] The housing is hinged to a top cover, and a PLC controller is installed on the inner top wall of the top cover;

[0010] In one or more embodiments of this utility model, a pair of connecting buckles are connected between the box body and the top cover to lock the box body and the top cover so that personnel can safely move the entire experimental box.

[0011] In one or more embodiments of this utility model, a pair of L-shaped seats are symmetrical to each other, and the L-shaped seats are provided with V-shaped grooves. The V-shaped grooves are used to engage shaft-type workpieces, thereby restricting the movement of shaft-type workpieces in the y-axis direction and their rotation in the y-axis and z-axis directions.

The height of the column is greater than the height of the L-shaped seat. One end of the shaft-like workpiece will contact the column, thereby restricting the movement of the shaft-like workpiece in the x-axis direction.

[0013] In one or more embodiments of this utility model, a motor base is installed on the side of the L-shaped base away from the column, and a servo motor is installed on the motor base.

[0016] In one or more embodiments of this utility model, the end of the set screw near the motor base is connected to a connecting end, which is connected to the output end of the servo motor. When the servo motor is running, the servo motor can drive the connecting end to rotate, which in turn can drive the set screw to rotate, so as to fix the shaft-type workpiece.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0034] like Figures 1 to 7 As shown, an embodiment of the present invention provides a shaft-type tooling fixture experimental box, which includes a box body 1, a base 2, a sensor base 3, and an industrial control computer 4.

[0035] The box body 1 is hinged to the top cover 101. When the top cover 101 is closed, it is locked and fixed by a pair of connecting buckles 103, which makes it convenient for staff to move the experimental box.

[0036] In addition, a PLC controller 102 is installed on the inner top wall of the upper cover 101. The PLC controller 102 is used to control the operation of the servo motor 204 and the rotary cylinder 209.

[0037] Specifically, a pair of connecting buckles 103 are connected between the box body 1 and the top cover 101 to lock the box body 1 and the top cover 101 so that the staff can safely move the entire experimental box.

[0038] like Figures 1 to 7 As shown, the base 2 is installed inside the housing 1. The base 2 is used to install the L-shaped seat 201, the column 202, the motor seat 203, the set screw seat 205, the cylinder seat 208, and the sensor seat 3.

[0039] The base 2 is equipped with a pair of L-shaped seats 201, which are symmetrical to each other. Each L-shaped seat 201 has a V-shaped groove 2010. The V-shaped groove 2010 is used to accommodate shaft-like workpieces for fixing them, making it difficult for them to move in the y-axis direction or rotate in the y- and z-axis directions. Simultaneously, the L-shaped seats 201 can be used to clamp and fix different types of shaft-like workpieces.

[0040] In addition, a positioning component is installed around the L-shaped seat 201, which is used to fix the shaft workpiece between a pair of L-shaped seats 201.

[0041] Specifically, the positioning component includes a column 202, which is bolted to the base 2. The height of the column 202 is greater than the height of the L-shaped seat 201. When a shaft-like workpiece is installed between a pair of L-shaped seats 201, one end of the shaft-like workpiece will contact the column 202, thereby restricting the movement of the shaft-like workpiece in the x-axis direction.

[0042] like Figures 1 to 7 As shown, a motor base 203 is installed on the side of the L-shaped base 201 away from the column 202. A servo motor 204 is installed on the motor base 203. The servo motor 204 is electrically connected to the PLC controller 102. The servo motor 204 is used to drive the set screw 206 and the connecting end 207 to rotate.

[0043] A set screw seat 205 is provided between the motor base 203 and the L-shaped base 201. The set screw seat 205 is mounted on the base 2 and is used to install the set screw 206 and the connecting end 207. The set screw 206 is threaded onto the set screw seat 205. The set screw 206 cooperates with the column 202 to restrict the movement of the shaft-like workpiece in the x-axis direction and determine the position of the shaft-like workpiece.

[0044] Additionally, a connecting end 207 is connected to the end of the set screw 206 near the motor base 203, and the connecting end 207 is connected to the output end of the servo motor 204. When the servo motor 204 is running, the servo motor 204 can drive the connecting end 207 to rotate, which in turn can drive the set screw 206 to rotate, so as to fix the shaft-type workpiece.

[0045] Specifically, the output end of the servo motor 204 is a polygonal column, and the connecting end 207 is provided with an insertion slot. One end of the polygonal column is inserted into the insertion slot, and the depth of the insertion slot is greater than the insertion depth of the polygonal column. When the servo motor 204 runs, the polygonal column can drive the connecting end 207 to rotate, which in turn drives the set screw 206 to rotate. Since the depth of the insertion slot is greater than the length of the polygonal column, the set screw 206 can move in the x-axis direction.

[0046] like Figures 1 to 7 As shown, a pressing component is installed around the L-shaped seat 201 to fix the shaft workpiece between a pair of L-shaped seats 201, making it difficult for the shaft workpiece to move in the y-axis direction.

[0047] The pressing component includes a cylinder base 208, which is mounted on the base 2 and located on one side of the L-shaped seat 201. A rotary cylinder 209 is mounted on the cylinder base 208, which can drive the pressure plate 210 to rotate and rise.

[0048] In addition, a pressure plate 210 is installed at the free end of the rotary cylinder 209. The pressure plate 210 can press down on the shaft-like workpiece, so that the shaft-like workpiece can be fixed in the V-groove 2010 and is not easy to move in the y-axis direction.

[0049] Specifically, a clamping screw 211 is threaded onto the pressure plate 210. When the clamping screw 211 contacts the shaft-like workpiece, it makes it difficult for the shaft-like workpiece to rotate in the y-axis direction.

[0050] Preferably, the end of the clamping screw 211 is connected to an elastic pad, which is less likely to cause wear on the surface of shaft-type workpieces.

[0051] like Figures 1 to 7 As shown, a sensor base 3 is also installed on the base 2, and a sensor 301 is installed on the sensor base 3. The sensor 301 is used to detect the position of the shaft workpiece and send the detection signal to the industrial control computer 4.

[0052] like Figures 1 to 7 As shown, an industrial control computer 4 is installed on the inner top wall of the upper cover 101. The sensor 301 is electrically connected to the industrial control computer 4, and the industrial control computer 4 is electrically connected to the PLC controller 102. The operator can program the industrial control computer 4 and use the program to control the industrial control computer 4. Through the cooperation of the industrial control computer 4, the PLC controller 102, and the sensor 301, shaft-type workpieces can be better fixed.

[0053] Preferably, the PLC controller 102, servo motor 204, rotary cylinder 209 and industrial computer 4 in this application are all commercially available products and can be purchased and used directly.

[0054] In practical use, the shaft-like workpiece is placed in the V-groove 2010. The sensor 301 detects the position of the shaft-like workpiece, and the information detected by the sensor 301 is transmitted to the industrial control computer 4. The relevant program in the industrial control computer 4 determines the correct position of the shaft-like workpiece. If the position is incorrect, the shaft-like workpiece needs to be repositioned. If the position is correct, the servo motor 204 is controlled by the PLC controller 102. The servo motor 204 drives the connecting end 207 and the set screw 206 to rotate, so that the set screw 206 moves closer to the shaft-like workpiece. With the cooperation of the column 202, the shaft-like workpiece can be clamped and fixed, making it difficult for the shaft-like workpiece to move in the x-axis direction.

[0055] The rotary cylinder 209 is controlled to rotate and raise the pressure plate 210 a certain distance before lowering it to clamp the shaft-like workpiece. At this time, the clamping screw 211 will contact the surface of the shaft-like workpiece, thus making it difficult for the shaft-like workpiece to move or rotate in the y-axis and z-axis directions. When it is necessary to disassemble the shaft-like workpiece, simply control the set screw 206 to return to its original position, and simultaneously control the rotary cylinder 209 to rotate and lower back to its original position. The clamping and fixing steps for the shaft-like workpiece in this application are relatively simple, facilitating quick operation by staff and improving experimental efficiency.

[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
