Description

Technical Field

[0001] The present application relates to the technical field of screwdrivers, and particularly to a fixture installation device, a fixture, and a screwdriver. Background Art

[0002] When screwing screws onto the product shell, if manual screwing is used, not only is the efficiency low, but also the phenomenon of missed screwing is likely to occur. Therefore, at present, when mass-producing and processing products, automatic screwdrivers are usually used. When using an automatic screwdriver, the product needs to be placed at a designated position. Based on the coordinates of the product, the position of the screw is determined through programming preset by the computer. Using an automatic screwdriver to screw the product shell not only has high efficiency, but also can automatically alarm when abnormal phenomena such as missed screwing occur.

[0003] When using an automatic screwdriver, since the product needs to be placed at a designated position, a fixture capable of accommodating the product is required to limit the position of the product. When the product is placed on the fixture, the position of the product can be fixed. Therefore, on the screwdriver platform, different screwdriver fixtures are often required for different products. For example, after product A is processed, if product B needs to be processed, the screwdriver fixture corresponding to product A needs to be removed from the screwdriver, and the screwdriver fixture corresponding to product B needs to be installed on the screwdriver to continue processing product B.

[0004] However, currently, screwdriver fixtures are usually fixed to the base of the screwdriver operation table with multiple screws. Each time the screwdriver fixture needs to be replaced, multiple screws need to be removed and installed, and the operation is cumbersome.

Detailed implementation manners

[0033] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present application. Therefore, the present application is not limited by the specific implementations disclosed below.

[0034] Based on the above background art, when screwing a screw into the product housing, if manual screwing is used, not only is the efficiency low, but also the phenomenon of missed screwing easily occurs. Therefore, currently, when mass-producing and processing products, an automatic screw machine is usually used. When using the automatic screw machine, the product needs to be placed at a designated position. Based on the coordinates of the product, the position of the screw is determined through the programming pre-set by the computer. Using the automatic screw machine to screw the screw into the product housing not only has high efficiency, but also can automatically alarm when abnormal phenomena such as missed screwing occur.

[0035] When using the automatic screw machine, since the product needs to be placed at a designated position, a fixture capable of accommodating the product is required to limit the product. When the product is placed on the fixture, the position of the product can be fixed. Therefore, on the screw machine platform, different screw machine fixtures are often required for different products. For example, after product A is processed and product B needs to be processed, at this time, the screw machine fixture corresponding to product A needs to be removed from the screw machine, and the screw machine fixture corresponding to product B needs to be installed on the screw machine to continue processing product B. However, currently, the screw machine fixture is usually fixed to the base of the screw machine operating table with multiple screws, and multiple screws need to be removed and installed each time the screw machine fixture is replaced, resulting in cumbersome operations.

[0036] Based on this, the present application provides a fixture installation device, which can realize the installation and disassembly of the fixture through the first guide rail, the second guide rail on the fixture that cooperates with the first guide rail, the positioning pin, the movable rod that controls the movement of the positioning pin, and the positioning hole on the fixture that cooperates with the positioning pin. When installing the fixture, under the action of an external force, the second guide rail provided on the fixture slides into the first guide rail. When reaching the designated position, the positioning pin can move along the unfolding direction of the elastic member and be inserted into the positioning hole located on the second guide rail, so that the fixture is locked on the working surface of the workbench. When disassembling the fixture, the movable rod makes the positioning pin move along the compression direction of the elastic member under the action of an external force and disengages from the positioning hole, so that the fixture is in an unlocked state with the working surface of the workbench. Under the action of an external force and during the sliding of the second guide rail along the first guide rail, the positioning pin moves out of the positioning hole, so that the fixture is separated from the working surface of the workbench. The fixture installation device can conveniently install and disassemble the fixture.

[0037] The following combines Figures 1 - 5 to introduce in detail the specific structures and working principles of the fixture installation device, the fixture, and the screwdriver machine.

[0038] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 which are the structural schematic diagrams of the first guiding and positioning mechanism provided by the present application, Figure 2 which is the structural schematic diagram of the second guiding and positioning mechanism provided by the present application, Figure 3 and which is the schematic diagram of the installation state of the fixture installed on the fixture installation device provided by the present application. Figure 3 In , the fixture 30 is installed on the first guiding and positioning mechanism 10, and the bottom end of the fixture 30 has a second guiding and positioning mechanism 20 adapted to the first guiding and positioning mechanism 10.

[0039] Please continue to refer to Figure 1 In the embodiment of the present application, the fixture installation device includes: a first guiding and positioning mechanism 10 provided on the working surface of the workbench, the first guiding and positioning mechanism 10 includes a first guide rail 101 and a positioning pin 102, and a movable rod 103 that controls the movement of the positioning pin 102; the first guide rail 101 is in a convex shape or a groove shape, and the length direction of the first guide rail 101 is the same as the moving direction of the fixture 30.

[0040] Please continue to refer to Figure 2, the fixture 30 includes a second guiding and positioning mechanism 20 adapted to the first guiding and positioning mechanism 10 in the installation device of the fixture. The second guiding and positioning mechanism 20 includes a second guide rail 201 and a positioning hole 202. The second guide rail 201 is located on the relative installation surface of the fixture 30 and the first guide rail 101 and can be adapted to the first guide rail 101. Under the action of an external force, the second guide rail 201 provided on the fixture 30 can slide into the first guide rail 101. In specific implementation, the first guide rail 101 and the second guide rail 201 cooperate with each other. When the first guide rail 101 is in a convex shape, the second guide rail 201 is in a groove shape, and the positioning hole 202 is located in the groove of the second guide rail 201; when the first guide rail 101 is in a groove shape, the second guide rail 201 is in a convex shape, and the positioning hole 202 is located in the convex of the second guide rail 201.

[0041] In specific implementation, when the first guide rail 101 is in a convex shape, the cross-section of the first guide rail 101 is T-shaped. Correspondingly, the second guide rail 201 is in a groove shape, and the cross-section of the second guide rail 201 is concave; when the first guide rail 101 is in a groove shape, the cross-section of the first guide rail 101 is T-shaped. Correspondingly, the second guide rail 201 is in a convex shape, and the cross-section of the second guide rail 201 is T-shaped.

[0042] In the installation device of the fixture, as an embodiment, please continue to refer to Figure 2 , the positioning pin 102 is connected to one end of the movable rod 103 at the bottom end inside the first guide rail 101. The other end of the movable rod 103 extends outward from the first guide rail 101, and the extension length is greater than the width or length of the fixture 30. An elastic member 104 is nested on the movable rod 103. Under the elastic force of the elastic member 104, the movable rod 103 can push the positioning pin 102 to move along the elastic force direction of the elastic member 104. The elastic member 104 can specifically be a spring or other elastic members.

[0043] When the fixture is installed, under the action of an external force, the second guide rail 201 provided on the fixture 30 slides into the first guide rail 101. When it reaches the specified position, the positioning pin 102 can move along the unfolding direction of the elastic member 104 and be embedded into the positioning hole 202 located on the second guide rail 201, so that the fixture 30 is locked on the working surface of the workbench. When the fixture is disassembled, the movable rod 103 causes the positioning pin 102 to move along the compression direction of the elastic member 104 under the action of an external force, and the positioning pin 102 disengages from the positioning hole 202, so that the fixture 30 is in an unlocked state with the working surface of the workbench. Under the action of an external force, during the sliding of the second guide rail 201 along the first guide rail 101, the positioning pin 102 moves out of the positioning hole 202, and the fixture 30 is separated from the working surface of the workbench.

[0044] It should be noted that when the fixture is installed, the fixture 30 is slid into the first guide rail 101. Specifically, the second guide rail 201 on the fixture 30 cooperates with the first guide rail 101. Under the action of an external force, as the fixture 30 slides into the first guide rail 101, when the position of the positioning pin 102 corresponds to the position of the positioning hole 202, the positioning pin 102 can be embedded into the positioning hole 202. At this time, the fixture 30 is locked on the working surface of the workbench, and the fixture installation process is completed. When the fixture is disassembled, the movable rod 103 causes the positioning pin 102 to move along the compression direction of the elastic member 104 under the action of an external force, the positioning pin 102 moves out of the positioning hole 202, and the fixture 30 is in an unlocked state with the working surface of the workbench. Under the action of an external force, during the sliding of the second guide rail 201 along the first guide rail 101, the positioning pin 102 moves out of the positioning hole 202, and the fixture 30 is separated from the working surface of the workbench, and the fixture disassembly process is completed.

[0045] In specific implementation, the first guiding and positioning mechanism 10 further includes a sliding base 105. The sliding base 105 is installed on the working surface of the workbench, and the first guide rail 101 is installed on the sliding base 105; a receiving groove 106 is provided on the sliding base 105, and the movable rod 103 is received in the receiving groove 106. The height of the receiving groove 106 is equal to or greater than the diameter of the movable rod 103; under the push of the movable rod 103, the positioning pin 102 can horizontally move in a moving groove opened on the first guide rail 101, and the direction of the horizontal movement is perpendicular to the direction in which the second guide rail 201 slides along the first guide rail 101.

[0046] The length of the movable rod 103 is greater than the length of the receiving groove 106. A first stopper 107 is provided above the receiving groove 106 at the edge of the operating surface of the workbench. A second stopper 108 is provided at the other end of the movable rod 103. The elastic member 104 is located between the first stopper 107 and the second stopper 108. It should be noted that the first stopper 107 and the second stopper 108 are used to limit the elastic member 104 in the direction of the elastic force. In specific implementation, of course, holes can also be provided at one end of the movable rod 103, and pins can be provided in the holes to cooperate with the first stopper 107 to prevent the elastic member from popping out of the movable rod 103 under the action of external force.

[0047] As another implementation manner, a wedge-shaped slider is further provided in the first guide rail 101. One end of the wedge-shaped slider abuts against the bottom end of the positioning pin 102 located in the first guide rail 101, and the other end of the wedge-shaped slider abuts against one end of the movable rod 103. Under the action of the movable rod 103, the wedge-shaped slider can move the positioning pin 102 up and down in the axial direction. Please refer to Figure 4 and Figure 5 , Figure 4 which are schematic structural diagrams of a wedge-shaped slider provided in the first guide rail according to the present application, Figure 5 and which are schematic structural diagrams of another wedge-shaped slider provided in the first guide rail according to the present application. It should be noted that how the fixture installation device realizes the installation and disassembly of the fixture will be introduced later, and will not be elaborated here.

[0048] The above is the overall introduction of the fixture installation device provided by the present application.

When the fixture is installed, under the action of external force, the second guide rail provided on the fixture slides into the first guide rail, and when it reaches the specified position, the positioning pin can move along the unfolding direction of the elastic member and be embedded into the positioning hole located in the second guide rail, so that the fixture is locked on the operating surface of the workbench; when the fixture is disassembled, the movable rod moves the positioning pin along the compression direction of the elastic member under the action of external force and disengages from the positioning hole, so that the fixture is in an unlocked state with the operating surface of the workbench. Under the action of external force, and during the sliding of the second guide rail along the first guide rail, the positioning pin moves out of the positioning hole, so that the fixture is separated from the operating surface of the workbench. The fixture installation device can conveniently install and disassemble the fixture.

[0049] The present application further provides a fixture 30, which includes a second guiding and positioning mechanism 20 adapted to the first guiding and positioning mechanism 10 in the above-mentioned mounting device; the second guiding and positioning mechanism 20 includes a second guide rail 201 and a positioning hole 202. The second guide rail 201 is located on the relative mounting surface of the fixture 30 and the first guide rail 101 and can be adapted to the first guide rail 101. When the first guide rail 101 is in a convex shape, the second guide rail 201 is in a groove shape, and the positioning hole 202 is located in the groove of the second guide rail 201; when the first guide rail 101 is in a groove shape, the second guide rail 201 is in a convex shape, and the positioning hole 202 is located in the convex of the second guide rail 201; the positioning hole 202 is adapted to the positioning pin 102.

[0050] When the fixture is installed, under the action of an external force, the fixture 30 makes the second guide rail 201 slide along the first guide rail 101. When reaching the specified position, the positioning pin 102 can move along the unfolding direction of the elastic member 104 and be embedded into the positioning hole 202, so that the fixture 30 is locked on the working surface of the workbench; when the fixture is disassembled, the positioning pin 102 moves along the compression direction of the elastic member under the action of the movable rod and disengages from the positioning hole, so that the fixture 30 is in an unlocked state with the working surface of the workbench. During the sliding of the second guide rail 201 along the first guide rail 101, the positioning pin 102 moves out of the positioning hole 202, and the fixture 30 is separated from the working surface of the workbench.

[0051] As an embodiment, please continue to refer to Figure 2 , Figure 2 In, a guiding groove 203 for guiding the positioning pin 102 to be embedded into the positioning hole 202 is provided on the second guide rail 201.

When the fixture is installed, under the action of an external force, as the second guide rail 201 slides along the first guide rail 102, the positioning pin 102 slides into the guiding groove 203 from the entrance of the guiding groove 203, and when reaching the position of the positioning hole 202, the positioning pin 102 is embedded into the positioning hole 202; when the fixture is disassembled, the positioning pin 102 moves along the elastic force direction to the guiding groove 203 under the action of an external force and separates from the positioning hole 202. Under the action of an external force, during the sliding of the first guide rail 102 along the second guide rail 201, the positioning pin 102 moves out of the guiding groove 203, and the fixture 30 is separated from the working surface of the workbench.
