[0027] In an embodiment of the present utility model, as Figures 1 - 5 shown, a fixture for machining a workpiece housing is provided, including: a main board 1, a detachable clamping rod 2 is provided on the top of the main board 1; a clamping assembly, the clamping assembly is arranged on the top of the clamping rod 2 and is used for quickly clamping and fixing the workpiece, and a lapping assembly, the lapping assembly is arranged between the bottom of the clamping rod 2 and the main board 1 and is used for quickly fixing and installing the clamping rod 2. During use, the clamping assembly on the top of the clamping rod 2 can clamp and fix the edges of various housings, and at the same time, the lapping assembly can distribute and install a plurality of clamping rods 2 on the surface of the main board 1, so as to construct corresponding different specifications of fixtures for different models of housings, thereby making the device have better practicability.

[0028] Further, the clamping assembly includes: an upper sleeve rod 3 arranged on the top of the clamping rod 2, a clamping table 302 is provided on the top of the upper sleeve rod 3; a clamping groove 303 is opened on the top of the clamping table 302, electric push rods 304 are arranged on both inner walls of the clamping groove 303, the end of the electric push rod 304 is connected with a clamping plate 305, and the clamping plate 305 is slidably connected with the clamping groove 303. During use, the electric push rod 304 is started by pressing the switch 104. At this time, the electric push rod 304 on the clamping plate 305 will push the clamping plate 305 to move closer inside the clamping groove 303, and thereby clamp and fix the edge of the housing workpiece.

[0029] Further, a sliding rod 204 is provided at the top of the clamping rod 2, a sliding groove 301 is opened at the bottom of the upper sleeve rod 3, and the sliding rod 204 is slidably connected to the sliding groove 301. Anti-slip pads 205 are provided at the connecting parts of the clamping rod 2 and the upper sleeve rod 3. During use, by means of the sliding connection between the sliding rod 204 and the sliding groove 301, the user can lift the upper sleeve rod 3, rotate it and then put it down, enabling the upper sleeve rod 3 to rotate relative to the clamping rod 2. During the rotation process, the upper sleeve rod 3 can change the direction and drive the clamping table 302 and the clamping plate 305 to change the direction, so that it can adapt to the edge of the housing to achieve variable-direction clamping, making the clamping plate 305 more adaptable to various specifications of the housing for clamping, improving the practicability of the device. At the same time, when the upper sleeve rod 3 falls back to the top of the clamping rod 2, the anti-slip pads 205 can be padded together to increase the friction force, and under the action of the large friction force, prevent the upper sleeve rod 3 from rotating and causing the clamping to become unstable.

[0030] Further, magnets 206 are provided at the bottom of the upper sleeve rod 3 and the top of the clamping rod 2, and the magnetic poles of the two magnets 206 attract each other. During use, the magnets 206 can further increase the friction force between the upper sleeve rod 3 and the clamping rod 2, further prevent the upper sleeve rod 3 from rotating, make the placement and clamping of the device more stable, and improve the practicability of the device.

[0031] Further, a clamping pad 306 is covered on the surface of the clamping plate 305, and a plurality of grooves are opened on the clamping pad 306. The clamping pad 306 is made of rubber material as a whole. During use, the user can place the clamping pad 306 between the clamping plate 305 and the workpiece. The plurality of grooves can provide an adsorption effect similar to that of a suction cup, increasing the clamping stability during clamping, and at the same time, the clamping pad 306 can also reduce the damage of the clamping plate 305 to the workpiece during the clamping process.

[0032] Further, a push button switch 104 is provided on one side of the surface of the main board 1, and the push button switch 104 is electrically connected to the electric push rod 304. During use, the push button switch 104 is used to quickly start the device to achieve conduction and clamping, improving the practicability of the device.

[0033] In another embodiment of the present invention, as Figures 1 - 4 shown, the lapping assembly includes: a plurality of mounting openings 101 opened on the top of the main board 1; a mounting block 201 provided at the bottom of the clamping rod 2, and the mounting opening 101 is slidably connected to the mounting block 201. During use, by inserting the mounting block 201 into the mounting opening 101, the mounting block 201 can be quickly taken out of the mounting opening 101, and in this way, the mounting block 201 can be quickly inserted and fixed to the mounting opening 101, improving the use stability of the device.

[0034] Furthermore, a limiting groove 102 is formed on the inner wall of the installation opening 101. Limiting blocks 202 are provided on both sides of the installation block 201, and the limiting blocks 202 are slidably connected to the limiting groove 102. During use, by means of the sliding connection between the limiting blocks 202 and the limiting groove 102, the limiting blocks 202 can cooperate with the limiting groove 102 to guide the installation of the installation block 201, and at the same time, the insertion stability of the installation block 201 is improved by increasing the contact surface between the installation block 201 and the installation opening 101.

[0035] Furthermore, contact points 203 are provided on one side of the two limiting blocks 202 away from the installation block 201 and on the top of the sliding rod 204. Contact pieces 103 are provided on the inner walls of the limiting groove 102 and the sliding groove 301, and the contact points 203 are in contact with the contact pieces 103. During use, power supply is realized by the mutual contact between the contact pieces 103 and the contact points 203. When the user inserts the installation block 201 into the installation opening 101 and then adjusts the upper sleeve rod 3 to a suitable position, the contact points 203 on the limiting blocks 202 at the top of the sliding rod 204 will be connected to the contact pieces 103 inside the limiting groove 102 and the sliding groove 301, and power conduction and power supply between multiple separated structures are realized in this way, so that the electric push rod 304 can obtain power supply.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
