[0016] The present invention will be described in detail below with reference to the accompanying drawings.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] See Figures 1 to 5The utility model provides a drilling device for the piston hole of a cylinder seat, which includes a base 1 and a vertical block 2 vertically fixed to the upper end of the base 1. A positioning platform 3 with an avoidance hole is provided on the upper end of the base 1. The piston seat of the cylinder seat is placed flat on the positioning platform. The front end of the vertical block 2 is triangularly distributed with abutments 4. The three legs of the cylinder seat fitly rest against the abutments. A guide hole is longitudinally opened in the middle of the vertical block 2. The guide hole is elastically and slidably equipped with a guide column 7 driven by a cylinder 6. The crankshaft hole of the cylinder seat can be inserted into the guide column to guide the cylinder seat. A loosening clamp assembly 8 is connected to the guide column 7. A drilling rig 5 is provided downwardly above the positioning platform 3, and a support frame is provided on the rear side of the base 1. The drilling rig 5 and the cylinder 6 are arranged on the support frame. The cylinder releases the guide pin, and the guide pin moves backward while driving the clamping assembly to clamp the cylinder seat. The guide pin is separated from the crankshaft hole of the cylinder seat to prevent vibration from affecting the guide pin during drilling. The drilling rig drills the positioned piston hole of the cylinder seat, and then the cylinder pushes the guide pin forward. The guide pin moves forward while driving the clamping assembly to release the cylinder seat. At the same time, the guide pin penetrates the crankshaft hole of the cylinder seat so that the staff can remove the cylinder seat.

[0019] See Figure 1 、 Figure 3 、 Figure 4 The loosening assembly 8 includes a connecting plate 8.1 connected to the end of the guide post 7. Slide rods 8.2 are symmetrically provided on the left and right sides of the connecting plate 8.1. A clamping piece 8.3 is hinged to the front end of the slide rod 8.2. A torsion spring is connected between the slide rod 8.2 and the clamping piece 8.3. A sliding hole is longitudinally opened on the vertical block 2 to accommodate the sliding rod 8.2 and the clamping piece 8.3. The cylinder releases the connecting plate, the connecting plate, guide post, and sliding rod move backward, the sliding rod pulls the clamping piece into the sliding hole, the clamping piece clamps the cylinder block, and the guide post is separated from the crankshaft hole of the cylinder block to prevent vibration during drilling from affecting the guide post. After the piston hole is drilled, the cylinder pushes forward to push the connecting plate, the connecting plate, guide post, sliding rod, and clamping piece move forward. After the clamping piece is separated from the sliding hole, it expands to both sides under the action of the torsion spring. At the same time, the guide post penetrates the crankshaft hole of the cylinder block, allowing the staff to remove the cylinder block.

[0020] The connecting plate 8.1 is composed of a central disc connecting long strips on the left and right sides, and the guide column 7 is provided with an elastic member connecting the disc and the vertical block 2.

[0021] Clamp 8.3 consists of a hinged rod at the rear connected to a clamping strip at the front, with a sliding hole allowing the hinged rod to slide into place. The clamp is made of plastic, and the clamping strip is perpendicular to the hinged rod. When the hinged rod is pulled into the sliding hole, it remains longitudinally aligned, and the clamping strip rests against the crankshaft seat of the cylinder block, clamping the cylinder block securely.

[0022] The edge at the rear end of the articulated rod and the edge at the front end of the guide post 7 are all provided with rounded corners. The rounded corners of the guide post can facilitate the cylinder seat to penetrate, and the rounded corners of the articulated rod can facilitate the articulated rod to enter the sliding hole.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
