Description

Technical field:

[0001] The present application relates to the technical field of machine tool auxiliary tools, and in particular to a machine tool taper pin lifting device. Background technology:

[0002] In today's production workshops, especially in machine tool assembly sites, the installation and removal of tapered pins is a frequent and critical operation.

[0003] Chinese utility model patent application with application number 201020689189.7 - a tool for extracting an internally threaded tapered pin, which includes a pulling rod, a gripping portion and a pulling head; the pulling head is provided with a thread at least on one end, which is connected to the tapered pin via the thread, and the other end is connected to the bottom of the pulling rod. Pulling heads of different specifications are provided according to the specifications of the tapered pin to be extracted; the gripping portion is sleeved on the pulling rod and slides back and forth, and a limit block is provided at the top of the pulling rod to limit the further sliding of the gripping portion.

[0004] This patent uses a gripping part to hit a limit block and uses inertial force to pull out the internal threaded conical pin. However, in a relatively compact and complex environment such as machine tool assembly, the operating space is limited and the pulling tool is difficult to use, which greatly increases the difficulty and operation time of removing the locating pin. Utility model content:

[0005] In order to solve the above technical problems, the present invention provides a machine tool taper pin lifting device, which solves the technical problem that it is difficult to lift the taper pin in the narrow space of the machine tool. In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A machine tool taper pin lifting device, characterized by comprising:

[0007] A pry plate with a slot;

[0008] The base is connected to the pry plate in a hinged structure, and the base is provided with a through hole in the vertical direction, and the through hole is provided below the card slot;

[0009] Bolt, the nut of the bolt is located on the upper part of the pry plate, the screw rod of the bolt passes through the slot and the through hole and extends downward, and a limiting groove is provided on the peripheral wall of the screw rod, the limiting groove and the through hole are clearance-matched, and the height of the limiting groove is greater than the thickness of the base;

[0010] The pressure rod is connected to the skid plate in a fixed structure.

[0011] Furthermore, the horizontal cross-sections of the slots are all arranged in a U-shaped structure.

[0012] Furthermore, horizontal rods are provided on both sides of the nut of the bolt in a fixed structure manner.

[0013] Furthermore, the bolt is a hexagon socket bolt.

[0014] Furthermore, the hinge structure includes a hinge seat A, a hinge seat B and a positioning pin, and the hinge seat A and the hinge seat B are connected by the positioning pin;

[0015] The hinged seat A is connected to the base in a fixed structure;

[0016] The articulated seat B is connected to the skid plate in a fixed structure.

[0017] Furthermore, a retaining spring is provided at the end of the positioning pin.

[0018] Furthermore, the pressure rod is provided with an extension rod in a plug-in structure.

[0019] Furthermore, the included angle between the pressure rod and the skid plate is in the range of 120°-150°.

[0020] The beneficial effect of the utility model is that the patent utilizes a bolt to connect the tapered pin, and then uses a lever structure to remove the tapered pin from the pin hole, which can meet the pin removal work in a narrow space and greatly improve the efficiency of related work such as machine tool assembly.

[0021] The cooperation between the limiting groove and the through hole ensures that the bolt and the base are connected as an integral structure, thus preventing the bolt from falling off and affecting use, and improving convenience. Description of the drawings:

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will now be described in further detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the present invention. The specific implementation scheme of the present invention is as follows:

[0027] A machine tool taper pin lifting device includes a pry plate 4 with a slot 3, a pressure rod 7 is provided on one side of the pry plate 4 by a fixed structure, a base 2 is provided on the upper part of the pry plate 4 by a hinged structure, and a through hole 1 is provided in the vertical direction of the base 2, and the through hole 1 is provided below the slot 3; the nut of the bolt 6 is located on the upper part of the pry plate 4, and the screw rod of the bolt 6 extends downward through the slot 3 and the through hole 1. This patent utilizes a bolt to connect the taper pin, and then uses a lever structure to remove the taper pin from the pin hole, which can meet the pin lifting work in a narrow space and greatly improves the efficiency of machine tool assembly and other related work.

[0028] A limiting groove 5 is provided on the peripheral wall of the screw rod of the bolt 6, and the limiting groove 5 is clearance-matched with the through hole 1. The height of the limiting groove 5 is greater than the thickness of the base 2, ensuring that the bolt 5 can move up and down relative to the base 2, and also ensuring that the bolt and the base are connected as an integral structure, avoiding the bolt from falling off and affecting use, thereby improving convenience.

[0029] The horizontal cross-section of the clamping slot 3 is arranged in a U-shaped structure, and the opening is connected to the side wall, which can ensure that the bolt is clamped and the pry plate 4 can rotate around the intersection.

[0030] Specifically, the articulated structure includes an articulated seat A9, an articulated seat B10 and a positioning pin 11. The articulated seat A9 is connected to the articulated seat B10 through the positioning pin 11. The articulated seat A9 is connected to the base 2 in a fixed structure manner, and the articulated seat B10 is connected to the skid plate 4 in a fixed structure manner.

[0031] A retaining ring is provided at the end of the positioning pin 11. After the retaining ring is removed, the positioning pin 11 can be removed from the hinge seat A9 and the hinge seat B10 for replacement.

[0032] A washer can be installed on the outside of the bolt on the upper part of the base to prevent the pry plate at the slot 3 from damaging the bolt.

[0033] It should be noted that the pressure rod 7 is provided with an extension rod 12 in a plug-in structure, and the angle between the pressure rod 7 and the pry plate 4 is in the range of 120°-150°, which is more labor-saving. In this embodiment, it is 140°, and other embodiments can also be 120°, 130° and 150°.

[0034] It should be explained that, in one embodiment, horizontal rods 8 are provided on both sides of the nut of the bolt 6 in a fixed structure, so that the bolt 6 can be easily rotated by hand to connect with the tapered pin without the need for other tools.

[0035] In another embodiment, the bolt 6 is a hexagon socket bolt, which is convenient for connection using tools.

[0036] The working principle and working process of this utility model are as follows:

[0037] When the tapered pin needs to be removed, the base 2 is placed on the tapered hole, the lower part of the bolt 6 is inserted into the tapered hole, the bolt 6 is rotated to engage with the tapered pin thread until the nut of the bolt contacts the upper end surface of the pry plate 4, and then one end of the extension rod 12 is inserted into the outside of the pressure rod 7, and the other end of the extension rod 12 is pressed down. The nut is applied with the lever action, and the pry plate 4 rotates around the positioning pin 11. The other end of the pry plate 4 moves obliquely upward and contacts the lower part of the nut. The bolt 6 drives the tapered pin to be pulled out of the tapered hole, and the operation is completed.
