Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

Example (b): as shown in fig. 1, a PLC shell lens installation device, including mounting panel 1, install cylinder 2 on mounting panel 1, be equipped with the work piece seat 3 that is used for placing the work piece on mounting panel 1, work piece seat 3 includes bottom plate 31 and integrative smelting tool 32 that sets up on bottom plate 31, and the workman places the PLC casing on smelting tool 32 to place the lens on the casing, fixedly connected with pressure head 4 on cylinder 2's the piston rod, cylinder 2 compresses tightly the lens on the PLC shell through pressure head 4.

As shown in fig. 1, the bottom plate 31 and the tool 32 can be detached from the support plate 1, so that the workpiece seats 3 with different specifications of the tool 32 can be replaced to adapt to different PLC housings.

As shown in fig. 3 and 4, the bottom surface of the bottom plate 31 is integrally provided with an inserting column 5, the support plate 1 is provided with a slot 6 for inserting the inserting column 5, the inserting column 5 is integrally provided with a limit deviation column 7, the support plate 1 is provided with a limit deviation groove 8 for vertically inserting the limit deviation column 7, and the limit deviation groove 8 is communicated with the slot 6. Be provided with rack 9 towards one side of limit inclined to one side groove 8 at limit inclined to one side post 7, rotate on the mounting panel 1 and be connected with pivot 10, pivot 10 towards a gear of limit inclined to one side groove 8's one end tip fixedly connected with, the gear meshes with rack 9 mutually, pivot 10 relative pivoted sets up in mounting panel 1, and mounting panel 1 is stretched out to the one end that the gear was kept away from to pivot 10, and the tip fixedly connected with drawing disk 17 of mounting panel 1 is stretched out to pivot 10.

When the workpiece seat 3 of the support plate 1 is mounted on the support plate 1, a worker longitudinally inserts the deviation limiting column 7 from the upper end of the deviation limiting groove 8, and the rack 9 is meshed with the gear to drive the rotating shaft 10 to rotate clockwise. The peripheral wall of the gear is provided with a sliding block 12, the sliding block 12 is arranged on the support plate 1 in a relatively sliding mode, a one-way bearing 11 is arranged between the sliding block 12 and the peripheral wall of the rotating shaft 10, the outer ring of the one-way bearing 11 is fixedly connected with the sliding block 12, the inner ring of the one-way bearing 11 is fixedly connected with the peripheral wall of the rotating shaft 10, and the rotating shaft can only rotate clockwise through the one-way bearing 11. Due to the one-way bearing 11, when the deviation limiting column 7 is inserted into the deviation limiting groove 8, the rack 9 drives the gear to rotate clockwise; however, when the deviation-limiting column 7 is drawn out from the deviation-limiting groove 8, the one-way bearing 11 cannot rotate anticlockwise, that is, the deviation-limiting column 7 cannot be drawn out vertically upwards from the deviation-limiting groove 8, so that when a worker inserts the workpiece seat 3 into the slot 6 in the slot 6, the position fixation of the workpiece seat 3 is realized through the one-way bearing 11.

In order to enable the workpiece holder 3 to be replaced with a different workpiece holder 3 from the socket 6, the carrier plate 1 is provided with a control mechanism for driving the gear to move, and the control mechanism is used for releasing the gear from a state of meshing with the rack 9, so that the workpiece holder 3 can be freely drawn out from the socket 6.

The control mechanism comprises a sliding groove 13 for sliding the sliding block 12, a first spring 14 is arranged in the sliding groove 13, the first spring 14 is sleeved on the outer side of the rotating shaft 10, and when the first spring 14 is in a normal state, the first spring 14 pushes the gear to a position meshed with the pile inserting through elastic force. When a worker disengages the gear from the rack 9, the worker needs to overcome the elastic force of the first spring 14 to pull the gear until the gear is disengaged from the rack 9, the placement groove 15 is formed in the inner wall of the deviation limiting groove 8 of the support plate 1, and the gear is finally placed in the placement groove 15 after the rotating shaft 10 is pulled.

As shown in fig. 2, after the worker keeps the gear in the receiving groove 15 by overcoming the elastic force of the first spring 14, in order to prevent the first spring 14 from freely returning, a catch 16 is slidably connected to the bracket plate 1, when the catch 16 slides to a position overlapping with the projection of the pull plate 17 and the catch 16 is at the part between the pull plate 17 and the outer wall of the bracket plate 1, the catch 16 is pressed against the outer wall of the bracket plate 1 by the pull plate 17, so that the gear does not freely slide to be engaged with the rack 9 under the action of the first spring 14, and the workpiece holder 3 can be separated from the bracket plate 1.

Besides, the upright post 18 is fixedly connected to the support plate 1, the blocking piece 19 is rotatably connected to the upright post 18, and the blocking piece 19 abuts against the upper surface of the bottom plate 31 after rotation so as to ensure the stability of the workpiece seat 3. The bottom of the slot 6 is provided with a second spring 20, the second spring 20 is compressed when the insert post 5 is inserted into the slot 6, and the workpiece seat 3 can be ejected out of the slot 6 under the elastic force of the second spring 20 after the gear is disengaged from the rack 9.

The above detailed description merely describes the preferred embodiments of the present invention and does not limit the scope of the present invention. Without departing from the design concept and spirit scope of the present invention, the ordinary skilled in the art should belong to the protection scope of the present invention according to the present invention provides the text description and drawings to the various modifications, replacements and improvements made by the technical solution of the present invention. The scope of protection of the present invention is determined by the claims.
