DETAILED DESCRIPTION

[0034] The following will be described in detail in combination with the accompanying drawings. Figures 1-6 The application is further described in detail.

[0035] The embodiment of the application discloses an operating mechanism bottom plate assembly clamp.

[0036] Embodiment 1

[0037] Referring to Figure 1 , Figure 2 and Figure 3 , the operating mechanism bottom plate assembly clamp comprises a base 1 which is detachably connected to an assembly table through bolts, and a plurality of positioning holes 2 corresponding to a plurality of shaft columns 03 are formed in the base 1; in the embodiment, the number of the positioning holes 2 is two, the shaft column 03 is in sliding fit with the corresponding positioning hole 2, and a groove 3 is formed in the inner side wall of each positioning hole 2; the axis direction of the groove 3 is perpendicular to the axis direction of the positioning hole 2; a plug-in block 31 in plug-in fit with the avoiding groove 04 is slidably connected in each groove 3; the plug-in block 31 is provided with a pushing slope 311 away from the inner bottom wall of the positioning hole 2; the pushing slope 311 is in sliding fit with the plug-in column; the pushing slope 311 is inclined from top to bottom along the groove 3 towards the avoiding groove 04; and the plug-in block 31 is provided with a flat surface 312 away from the pushing slope 311.

[0038] Referring to Figure 3 and Figure 4 , an abutting spring 32 is arranged in each groove 3; one end of the abutting spring 32 is fixedly connected to the inner side wall of the groove 3 away from the positioning hole 2, and the other end is fixedly connected to the plug-in block 31; when the avoiding groove 04 is connected with the groove 3, the abutting spring 32 abuts the plug-in block 31 in the avoiding groove 04; and the flat surface 312 is tightly attached to the inner bottom wall of the avoiding groove 04.

[0039] In the process of assembling the bottom plate, the worker places the bottom plate on the base 1 and inserts the shaft column 03 into the positioning hole 2. Under the guidance of the pushing slope 311, the shaft column 03 pushes the plug-in block 31 to move towards the inside of the recess 3 during the descending process in the positioning hole 2. At this time, the abutting spring 32 is in a compressed state. When the shaft column 03 moves to the avoidance groove 04 which is communicated with the recess 3, the pressure on the abutting spring 32 disappears. The abutting spring 32 resets to push the plug-in block 31 to insert into the inside of the avoidance groove 04. At this time, under the plug-in cooperation of the plug-in block 31 and the avoidance groove 04, the vertical displacement of the bottom plate cannot be generated. At the same time, under the plug-in cooperation of the positioning hole 2 and the shaft column 03, the horizontal displacement of the bottom plate is limited. Therefore, the fixation of the bottom plate on the base 1 is realized. The position deviation of the bottom plate during the assembling process is avoided. The position of the bottom plate does not need to be adjusted by the worker for many times. The assembling efficiency of the bottom plate is improved. At the same time, through the abutting of the plane 312 and the inner bottom wall of the avoidance groove 04, the vertical loosening or displacement of the bottom plate caused by external force and other factors during the assembling process is effectively avoided. The stability of the connection between the plug-in block 31 and the avoidance groove 04 is further improved.

[0040] With reference to Figure 3 and Figure 4 , in order to facilitate the removal of the bottom plate after assembly, the base 1 is provided with a pushing groove 4 which is communicated with the recess 3. The axis of the pushing groove 4 is perpendicular to the axis of the positioning hole 2. A pushing rod 41 is slidably connected in the pushing groove 4. The pushing rod 41 extends to the end of the pushing groove 4 and is fixedly connected with the plug-in block 31. The end of the pushing rod 41 away from the plug-in block 31 extends to the outside of the pushing groove 4.

[0041] With reference to Figure 3 and Figure 4 , the base 1 is provided with a sliding groove 5 which corresponds to the mounting shaft 02. The axis direction of the sliding groove 5 is parallel to the axis direction of the positioning hole 2. A jacking rod 51 is slidably connected in the sliding groove 5. When the plug-in block 31 is plugged into the inside of the avoidance groove 04, the end face of the mounting shaft 02 abuts against the end face of the jacking rod 51. The base 1 is provided with a driving assembly 6 which drives the jacking rod 51 to move upwards along the sliding groove 5. In this embodiment, the driving assembly 6 includes a gas cylinder (not shown in the figure) which is fixedly installed in the assembling table. The output shaft of the gas cylinder extends to the inside of the base 1 and is connected with the jacking rod 51.

[0042] When the bottom plate needs to be removed after assembly, the worker pushes the push rod 41 towards the positioning hole 2, the push rod 41 moves the push-in block 31 to move towards the direction of the abutting spring 32, the abutting spring 32 is compressed, the push-in block 31 is separated from the avoiding groove 04, thereby releasing the vertical fixing restriction of the bottom plate, then the air cylinder in the assembly table automatically operates, the air cylinder starts to drive the top rod 51 to rise along the length direction of the sliding groove 5, the installation column is pushed to rise in the process of the top rod 51 rising, thereby a gap is generated between the shaft column 03 and the positioning hole 2, the bottom plate gradually separates from the base 1, at this time the worker removes the bottom plate from the base 1, and removes the force acting on the push rod 41 after the removal is completed, so that the bottom plate is conveniently removed from the base 1, and the difficulty in disassembly caused by the close fit between the insertion column and the inner wall of the positioning hole 2 is avoided, thereby improving the disassembly efficiency of the bottom plate from the base 1, and further improving the assembly efficiency of the bottom plate.

[0043] The embodiment of the operation mechanism bottom plate assembly clamp is: when the bottom plate is assembled, the worker places the bottom plate on the base 1 and inserts the shaft column 03 into the positioning hole 2, under the guidance of the push-in inclined surface 311, the shaft column 03 pushes the push-in block 31 to move towards the inside of the recess 3 in the process of descending in the positioning hole 2, at this time the abutting spring 32 is in a compressed state, when the shaft column 03 moves to the avoiding groove 04 and the recess 3 are communicated, the pressure on the abutting spring 32 disappears, the abutting spring 32 resets to push the push-in block 31 into the avoiding groove 04, at this time the bottom plate cannot be vertically displaced under the insertion and cooperation of the push-in block 31 and the avoiding groove 04, and the horizontal displacement of the bottom plate is limited under the insertion and cooperation of the positioning hole 2 and the shaft column 03, thereby the fixation of the bottom plate on the base 1 is realized, the position deviation of the bottom plate in the assembly process is avoided, the worker does not need to adjust the position of the bottom plate multiple times, and the assembly efficiency of the bottom plate is improved.

[0044] Embodiment 2

[0045] Reference Figure 5 and Figure 6The difference between the embodiment and embodiment 1 is that the driving assembly 6 comprises a guide block 61 slidably connected in the base 1, the base 1 is provided with a guide groove 7 slidably matched with the guide block 61, the guide groove 7 is arranged in communication with the sliding groove 5 and has an axis perpendicular to the axis of the sliding groove 5, the guide block 61 is provided with a guide inclined surface 611, the guide inclined surface 611 is arranged in an inclined manner from top to bottom along the direction from the sliding groove 5 to the guide groove 7, the guide inclined surface 611 is provided with a limiting groove 8 along the inclined direction, the limiting groove 8 is slidably connected with a limiting block 81, the end of the top rod 51 close to the sliding groove 5 is fixedly connected with the limiting block 81, under the limiting and guiding of the limiting groove and the limiting block 81, the top rod 51 can only move along the inclined direction of the guide inclined surface 611, the end of the guide block 61 is fixedly connected with a connecting rod 62, the connecting rod 62 is slidably connected in the guide groove 7, and the connecting rod 62 is connected with the two push rods 41 through a cross rod (not shown in the figure).

[0046] With reference to Figure 5 and Figure 6 , the end of the guide block 61 away from the connecting rod 62 is provided with a flat section 612, the length direction of the flat section 612 is parallel to the length direction of the guide groove 7, the limiting block 81 is slidably matched with the flat section 612, in the initial state, the limiting block 81 is arranged at the end of the flat section 612 away from the guide inclined surface 611, when the plug-in block 31 is separated from the avoiding groove 04, the limiting block 81 moves to the position where the flat section 612 is in communication with the guide inclined surface 611, the arrangement of the flat section 612 provides a transition displacement amount for the movement of the top rod 51, and avoids time delay or mechanical failure caused by the uncoordinated action of the top rod 51 and the plug-in block 31.

[0047] With reference to Figure 5 and Figure 6 , the top of the top rod 51 is detachably connected with a rubber buffer pad 511 through a magic tape, the rubber buffer pad 511 can effectively buffer the impact force between the top rod 51 and the bottom plate, so that the surface of the bottom plate is prevented from being scratched, worn or even locally deformed due to the direct contact between the hard material of the top rod 51 and the bottom plate.

[0048] The implementation principle of the operation mechanism bottom plate assembly clamp is as follows: in the process that the push rod 41 pushes the plug-in block 31 to separate from the avoiding groove 04, the push rod 41 moves to drive the guide block 61 to move, because the sliding groove 5 limits the top rod 51 to only move vertically, the movement of the guide block 61 causes the relative displacement between the limiting block 81 and the flat section 612, so that the vertical movement of the top rod 51 does not cause the movement of the plug-in block 31 to be stuck when the plug-in block 31 has not separated from the avoiding groove 04, and when the plug-in block 31 separates from the avoiding groove 04, the limiting block 81 moves to the position where the guide inclined surface 611 is in communication with the flat section 612.

[0049] Subsequently, the worker continues to push the push rod 41 inward, the push rod 41 drives the guide block 61 to continue to slide inward along the guide groove 7, in the process of moving the guide block 61, the top rod 51 moves from low to high along the inclined direction of the guide inclined surface 611, the transverse movement of the guide block 61 is converted into the vertical rising of the top rod 51 in the sliding groove 5, the top rod 51 moves upward to push the push plate to move upward, thereby facilitating the worker to take out the push plate;

[0050] After the bottom plate is taken out, the worker cancels the force on the push rod 41, the abutting spring 32 resets to push the push rod 41 to reset, thereby realizing the reset of the top rod 51 and the plug-in block 31. The synchronous operation of the unlocking of the plug-in block 31 and the ejection operation of the top rod 51 is realized by such setting, without the need to set an external driving source to drive the top rod 51 to rise and fall, effectively simplifying the overall structure of the clamp.

[0051] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
