Description

Hydraulic bolt dismounting device

Technical Field

The utility model relates to a dismounting device for dismantling the bolt in box or the machine because oil or other liquid dip connecting piece, can't normally take out.

Background

The main shaft on the existing oil press is wrapped by two shells, the shells are fixed together through bolts, hereinafter referred to as main shaft shells for short, the bolt arrangement mode is up-down single-row type fixation, oil is pressed from the inside of the main shaft of the oil press shaft, after long-time work, oil in the main shaft shell is immersed into the space between the bolt and the connected piece, and the bolt and the connected piece are slowly solidified, so that the binding power of the bolt and the connected piece is increased. The connection of the bolt on the main shaft shell is detachable, the original detaching method is that after the nut is detached, a top shaft with the outer diameter smaller than the diameter of the bolt is manually used by a hammer to prop the nut, the bolt head is hit from the nut, the labor is wasted, the bolt is very dangerous, the bolt is damaged by vibration and deviation generated to the bolt or the shell, and the sealing performance of the shell is also damaged.

Disclosure of Invention

In order to achieve the above purpose, the utility model discloses a technical scheme is:

the utility model provides a bolt hydraulic pressure dismounting device, includes that L shape main part supports, the horizontal plate that the main part supported be located the top of vertical board, its characterized in that: a hydraulic cylinder is fixed on the outer wall of the vertical plate supported by the main body, a connecting hole is formed in the vertical plate, a screw sleeve is fixed on the inner wall of the vertical plate at the position corresponding to the connecting hole, the screw sleeve is used for inserting a screw of a bolt to be disassembled, and a push rod of the hydraulic cylinder arranged along the horizontal direction can penetrate through the connecting hole to enter the screw sleeve;

a right-angle groove is formed in the outer wall of the horizontal plate supported by the main body and faces towards the inside of the horizontal plate, a threaded hole is formed in the vertical side wall of the right-angle groove and faces towards the inside of the horizontal plate, the axis of the threaded hole is arranged along the horizontal direction, a spring rod is fixed at the corner of the right-angle groove above the threaded connecting hole along the horizontal direction, a spring is sleeved on the spring rod, the inner side rod section of a guide rod arranged along the horizontal direction sequentially penetrates through a locking nut and an opening in the upper part of a clamping plate arranged along the vertical direction and is in threaded connection with the threaded hole, the clamping plate is tightly pressed with the outer end of the spring rod through the locking nut and tightly presses the spring between the clamping plate and the vertical side wall of the;

the lower part of the clamping plate is provided with a screw head sleeve which is used for installing the head of a bolt to be disassembled; the horizontal axes of the screw head sleeve, the screw rod sleeve and the connecting hole are positioned on the same horizontal straight line.

The utility model has the advantages that: the installation is convenient, the operation is simple, and the dismounting device is small. The clamping plate and the main body support are installed simultaneously, the size of the dismounting device is reduced, so that the dismounting device is suitable for narrow spaces, the support force of the spring rod is used as support, the guide rod enables the screw head sleeve and the screw rod sleeve to clamp the main shaft shell through the pretightening of the locking nut on the clamping plate, and the dismounting of the bolt can be completed once through the hydraulic cylinder.

Detailed Description

The present invention will be described in detail with reference to the following embodiments.

As shown in fig. 1 and 3 the utility model discloses a bolt hydraulic pressure dismounting device, support 4 including L shape main part, the main part support 4 the horizontal plate be located the top of vertical board the main part support 4 the outer wall of vertical board on be fixed with a pneumatic cylinder 8 vertical board on open and to have a connecting hole, with the inner wall of the vertical board of the corresponding position of connecting hole on be fixed with a screw rod cover 7, screw rod cover 7 be used for inserting the screw rod of the bolt of treating the dismantlement, set up along the horizontal direction the push rod of pneumatic cylinder 8 can pass the connecting hole and get into screw rod cover 7.

The outer wall of the horizontal plate of the main body support 4 is provided with a right-angle groove towards the inside of the horizontal plate, a vertical side wall of the right-angle groove is provided with a threaded hole with an axis arranged along the horizontal direction, a corner of the right-angle groove above the threaded connecting hole is fixed with a spring rod 3 along the horizontal direction, the spring rod 3 is sleeved with a spring, an inner side rod section of a guide rod 1 arranged along the horizontal direction sequentially penetrates through a locking nut 2, an opening on the upper part of a clamping plate 6 arranged along the vertical direction and is in threaded connection with the threaded hole, the clamping plate 6 is tightly pressed and arranged through the locking nut 2 and the outer end of the spring rod 3, and the spring is tightly pressed and arranged between the clamping plate and the vertical side wall of the right-angle groove.
