Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b):

as shown in fig. 1 to 5, the drilling device for the yellow oil hole of the excavator movable arm rear support comprises: a base plate 1; and a side plate 2 arranged on the bottom plate 1. A connecting component 4 is arranged between the bottom plate 1 and the side plate 2. The connecting assembly 4 comprises a fixing plate 41, the fixing plate 41 is fixed on the top of the bottom plate 1, and the bottom of the side plate 2 is hinged with one end edge of the fixing plate 41. When the support is placed between the bottom plate 1 and the side plate 2, the bottom of the support is in contact with the fixing plate 41, and the right side of the support is in contact with the side plate 2. In order to bring the side plate 2 into full contact with the right side of the seat of different specifications. An arc-shaped sleeve 42 is arranged on the bottom plate 1, an arc-shaped rod 43 is arranged on one side of the side plate 2 away from the fixed plate 41, one end of the arc-shaped rod 43 extends into the arc-shaped sleeve 42, and the arc-shaped rod 43 is connected with the arc-shaped sleeve 42 in a sliding manner; the arc-shaped lever 43 rotates around the hinge of the side plate 2 and the fixed plate 41.

In the present embodiment, the angle between the side plate 2 and the fixing plate 41 is adjusted to meet the different specifications of the mount. So that the side plate 2 is completely attached to the side surface of the support.

As shown in fig. 1 and 5, the arc-shaped sleeve 42 is provided with the fixing component 5, the fixing component 5 includes a threaded pipe 51, the outer side of the arc-shaped sleeve 42 is provided with a second through hole 421, the threaded pipe 51 is arranged at the second through hole 421, a first screw 52 is arranged on the threaded pipe 51 in a penetrating manner, and one end of the first screw 52 located at the second through hole 421 is processed with an anti-skid thread. A knob 53 is fixed to one end of the first screw 52 located outside the arc-shaped sleeve 42. When the position of the side plate 2 is determined, the operator rotates the knob 53, the knob 53 drives the first screw 52 to rotate, so that one end of the first screw 52 touches the arc-shaped rod 43, and the dead end presses the arc-shaped rod 43, thereby preventing the arc-shaped rod 43 from moving. It is noted that, since the second through hole 421 is located close to the side plate 2, the first screw 52 will contact the arc rod 43 after moving a certain distance without the arc rod 43 being out of contact with the arc sleeve 42.

Wherein, one side of bottom plate 1 is fixed with limiting plate 7, and limiting plate 7 is vertical setting. The purpose of the limiting plate 7 is to ensure that the support is placed at the correct position in the device and to make positioning preparation for subsequent punching. T shape spout 6T has been seted up to the one end that bottom plate 1 was kept away from to curb plate 2, and the one end of T shape spout 6T extends to the outside of curb plate 2, and the one end processing that the arc 3 and curb plate 2 contacted has T shape sliding block 61T, T shape sliding block 61T and T shape spout 6T sliding connection. Through sliding connection's mode, when the device does not use, can unpack the arc 3 apart and store alone, avoid receiving external force to disturb and damage.

In view of the above, it is desirable to provide,

the operator places the stand on the fixing plate 41 with one side of the stand touching the limiting plate 7.

Then, the operator releases the knob 53 to prevent the first screw 52 from contacting the arc rod 43, and then the operator rotates the side plate 2 to make one side of the side plate 2 completely contact with the right side surface of the support.

Next, the operator rotates the knob 53 in a reverse direction, the knob 53 drives the first screw 52 to rotate, the first screw 52 moves along the direction of the operator, so that one end of the first screw 52 contacts the surface of the arc rod 43, the arc rod 43 is firmly fixed, and the relative position between the arc rod 43 and the arc sleeve 42 is fixed. And the operator takes up the arc-shaped plate 3, inserts the T-shaped sliding block 61T into the corresponding T-shaped sliding groove 6T, and stops moving the arc-shaped plate 3 when one side of the T-shaped sliding block 61T touches one side of the inner wall of the T-shaped sliding groove 6T. At this time, the inner side surface of the arc plate 3 is attached to the arc surface of the top of the support. Finally, the operator uses a tool to extend the drill into the through tube 32, which limits the drilling direction during drilling due to the limiting effect of the through tube 32. Finally, the manufacture of the yellow oil hole is finished.
