[0029] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0030] Please refer to Figures 1-4 The utility model discloses a lock head hydraulic drilling machine clamp device, including the bottom plate 1:

[0031] The top end of bottom plate 1 is fixedly connected with clamping structure 2;

[0032] Clamping structure 2 includes fixed column one 201, and fixed column one 201 is fixedly connected to the top end of bottom plate 1, and the top end of fixed column one 201 is fixedly connected with connecting column one 202, and the outer side of connecting column one 202 is hinged with hinge 203, and one end of hinge 203 is fixedly connected with cylinder 204, and the right end of cylinder 204 is fixedly connected with piston rod 205, and the right end of piston rod 205 is fixedly connected with connecting column two 206;

[0033] Cylinder 204 is used as power source, when cylinder 204 works, piston rod 205 telescopes, and when piston rod 205 extends to the right, connecting column two 206 rotates around connecting column one 202, and this structural design provides power basis for subsequent clamping action, so that the whole clamping structure 2 can be flexibly opened and closed, and it is convenient to clamp and loosen the lock head workpiece.

[0034] Clamping structure 2 further includes fixed column two 207, and fixed column two 207 is fixedly connected to the top end of bottom plate 1, and the upper end of fixed column two 207 is hinged with connecting column three 208, and connecting column three 208 and connecting column two 206 are hinged;

[0035] Fixed column two 207 and connecting column three 208 are arranged, and are matched with connecting column two 206, form stable triangle connection structure, when cylinder 204 drives connecting column two 206 to move, connecting column three 208 can play the role of auxiliary support and guide, guarantee the stability of the movement of connecting column two 206, and then ensure the reliability of clamping structure 2 in the clamping process, prevent shaking or deviation in the clamping process.

[0036] Clamping structure 2 further includes connecting column four 209, and connecting column four 209, connecting column two 206 and connecting column three 208 are hinged, and the top end of connecting column four 209 is hinged with clamping arm 210, and the right end of clamping arm 210 is fixedly connected with clamping head 212;

[0037] The connecting column four 209 transmits the movement of the connecting column two 206 and the connecting column three 208 to the clamping arm 210, when the relative position of the connecting column two 206 and the connecting column three 208 changes due to the action of the air cylinder 204, the connecting column four 209 drives the clamping arm 210 to rotate around the hinge point of the connecting column four 209 and the fixed column three 211, so that the clamping head 212 can approach or move away from the workpiece, and the clamping and loosening actions of the lock head are realized, and the clamping position and force are accurately controlled,

[0038] The clamping structure 2 further comprises a fixed column three 211 fixedly connected to the top end of the bottom plate 1, and the fixed column three 211 and the clamping arm 210 are hinged;

[0039] The fixed column three 211 provides a stable support point for the clamping arm 210, so that the clamping arm 210 can stably rotate around this point during clamping, ensuring that the clamping head 212 maintains a stable posture when clamping the lock head, improving the clamping accuracy, and avoiding affecting the machining accuracy due to the shaking of the clamping arm 210.

[0040] The top end of the bottom plate 1 is fixedly connected with a drilling machine assembly 3;

[0041] The drilling machine assembly 3 comprises a fixed column four 301 fixedly connected to the top end of the bottom plate 1, and the top end of the fixed column four 301 is fixedly connected with a drilling machine main body 302, and the drilling machine main body 302 is located below the clamping head 212;

[0042] The drilling machine assembly 3 is fixed on the bottom plate 1 through the fixed column four 301, ensuring the stability of the drilling machine main body 302, and the drilling machine main body 302 is located below the clamping head 212, so that the clamped lock head workpiece and the drill bit of the drilling machine are in precise relative position, ensuring the accuracy of drilling processing, and enabling efficient drilling operation of the lock head.

[0043] The bottom end of the bottom plate 1 is provided with a shock pad made of rubber material, which is used to reduce the vibration transmission during drilling machine operation;

[0044] During the operation of the drilling machine, vibration will be generated, and the shock pad made of rubber material has good elasticity and damping characteristics, which can absorb the vibration energy generated during the operation of the drilling machine, reduce the vibration transmission from the drilling machine to the bottom plate 1, and then to the work platform or the ground, avoiding the influence of vibration on the machining accuracy, and also reducing the noise generated during the operation of the equipment, prolonging the service life of the equipment.

[0045] The inner side of the clamping head 212 is provided with anti-skid lines in a sawtooth structure, which is used to enhance the clamping stability of the workpiece;

[0046] The sawtooth anti-skid lines increase the friction between the clamping head 212 and the lock head workpiece, which can effectively prevent the lock head from slipping during clamping, even if the surface of the lock head is smooth, ensuring that the lock head remains in a fixed position during drilling processing, improving the accuracy and safety of processing.

[0047] The outer side of the cylinder 204 is provided with a protective cover, which is a detachable metal shell for preventing external debris from interfering with the operation of the cylinder 204.

[0048] In an industrial production environment, there are various dust, debris and other debris. The protective cover of the detachable metal shell can block these debris from entering the interior of the cylinder 204, preventing the debris from causing wear or damage to the piston, seal and other components of the cylinder 204, ensuring that the cylinder 204 can work normally and stably, prolonging the service life of the cylinder 204, and reducing the equipment downtime caused by cylinder 204 failure.

[0049] Working principle: when the lock head needs to be drilled, the cylinder 204 is started, the piston rod 205 of the cylinder 204 is extended, the connecting column two 206 is pushed to rotate clockwise (assuming the direction) around the connecting column one 202, the connecting column two 206 drives the connecting column three 208 and the connecting column four 209 connected thereto to move, the connecting column three 208 assists the connecting column two 206 to move stably under the support of the fixed column two 207, and the connecting column four 209 drives the clamping arm 210 to rotate counterclockwise around the fixed column three 211, so that the clamping head 212 gradually approaches the lock head workpiece. When the clamping head 212 contacts the lock head, the sawtooth anti-skid lines on the inner side of the clamping head 212 can tightly bite the lock head and provide stable clamping force. At this time, the drill bed body 302 of the drill bed assembly 3 is started, and the drill bit of the drill bed body 302 starts drilling the lock head. In the drilling process, the rubber shock pad at the bottom end of the bottom plate 1 can absorb the vibration generated by the drill bed, preventing the vibration from affecting the processing accuracy and equipment stability. At the same time, the protective cover on the outer side of the cylinder 204 can protect the cylinder 204 from external debris, ensuring the normal operation of the cylinder 204 and maintaining the stable clamping state of the clamping structure 2. After drilling is completed, the piston rod 205 of the cylinder 204 is retracted, driving the connecting column two 206 to rotate in the opposite direction, the clamping arm 210 rotates clockwise around the fixed column three 211 under the drive of the connecting column four 209, the clamping head 212 releases the lock head, and the entire processing flow is completed.

[0050] In this step, when the clamping head 212 contacts the lock head, the sawtooth anti-skid lines on the inner side of the clamping head 212 can tightly bite the lock head and provide stable clamping force.
