Description

Technical Field

[0001] The utility model relates to the technical field of automatic processing devices for rock drilling tools, in particular to an automatic rotating indexing column pressure device. Background Art

[0002] At present, the domestic rock drilling tool industry adopts interference fit cold pressing method or hot setting method to install the alloy column of the drill body. The method is to first knock the fixed tooth to the alloy hole, and then press it into the bottom of the hole with a press. Since the fit tolerance and pressure are difficult to control, the column teeth will be squeezed and cut and damage the hole wall, and the ball teeth will also be damaged by external force knocking. When the hot setting fixed tooth method is used, the drill body needs to be heated to a certain temperature. The operator uses tweezers or other tools to align the fixed tooth with the alloy hole on the drill body, and then uses a copper hammer to quickly knock the fixed tooth into the hole, using the thermal expansion and contraction characteristics of the steel body to achieve the purpose of fixing the tooth. The tooth fixing operation process must be fast and the time must be strictly controlled. The hot setting fixed tooth process is prone to thermal deformation of the alloy hole due to the force of the copper hammer knocking, which affects the strength of the fixed tooth. In addition, the tooth installation operation requires a certain amount of time, and the ideal fixed tooth temperature and uniformity of the drill body cannot be guaranteed, which affects the quality of the product fixed teeth. Although there are devices for pressing fixed teeth, such as patent announcement number CN 210587941U, a device for hot-inserting and fixing teeth of a column tooth drill is proposed. The four-bar structure composed of a fixed bracket, a movable bracket, the right short side of the pressure column connecting rod and a short connecting plate is used to press the column tooth alloy into the column tooth alloy in a lever-type force manner, which effectively avoids squeezing and cutting the alloy hole wall during hot-inserting the column tooth alloy and avoids damage to the column tooth alloy due to external force. However, since the pressure head performs a circular motion during use, it is not easy to align with the column tooth, and the force generated on the tooth is a force along the tangent direction of the pressure head running trajectory, so the force generated by the pressure head on the tooth is not completely aligned with the tooth groove. Therefore, it is necessary to adjust the angle of the drill body for multiple times for repeated pressing to ensure the tooth fixing effect. In addition, the four-bar structure is more laborious during use due to the large number of hinged positions. Utility Model Content

[0003] The utility model provides an automatic rotating indexing pressure column device, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problem that the prior indexing pressure column device needs to adjust the position of the drill bit for many times to perform repeated pressure setting, which is time-consuming and laborious.

[0004] In order to solve the above problems, the utility model discloses an automatic rotating indexing pressure column device, comprising a base, a pressure column device and a indexing device;

[0005] The pressure column device includes a support, a hydraulic rod and a pressure head. The support is provided on the left side above the base, the upper end of the support is provided with a hydraulic rod, and the lower end of the hydraulic rod is provided with a pressure head;

[0007] The indexing device includes a fixing part, a motor, a pulley, a indexing shaft, a indexing rod and a rotating sleeve. A fixing part is provided on the upper right side of the base.

DETAILED DESCRIPTION

[0018] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0019] like Figure 1-5 As shown, an automatic rotating indexing pressure column device comprises a base 1, a pressure column device and a indexing device;

[0020] The pressure column device includes a support member 2, a hydraulic rod 10 and a pressure head 11. The support member 2 is provided on the left side above the base 1, the hydraulic rod 10 is provided on the upper end of the support member 2, and the pressure head 11 is provided on the lower end of the hydraulic rod 10;

[0021] A bearing platform 4 is provided in the center above the base 1, and a working turntable 6 is movably connected above the bearing platform 4. A plurality of indexing platforms 7 are evenly distributed along the circumference above the working turntable 6, and a drill body 9 is provided on each indexing platform 7, and the drill body 9 can be located directly below the pressure head 11 when the working turntable 6 rotates;

[0022] The indexing device includes a fixing part 3, a motor 12, a pulley 13, a indexing shaft 14, a indexing rod 15 and a rotating sleeve 16. A fixing part 3 is provided on the upper right side of the base 1, and a motor 12 is provided above the base 1 at the right side of the fixing part 3. The output shaft of the motor 12 is fixedly connected with the pulley 13, and the pulley 13 is connected with the indexing shaft 14 through a belt. The lower end of the indexing shaft 14 passes through the fixing part 3 and is connected with the indexing rod 15. A rotating sleeve 16 capable of driving the indexing table 7 to rotate is fixedly connected below the indexing rod 15.

[0023] The indexing table 7 may be in a cone shape, with the smaller end of the cone facing the center of the working turntable 6 . When the rotating sleeve 16 rotates, it can contact two adjacent indexing tables 7 respectively.

[0024] Among them, the working pressure of the hydraulic rod 10 can be 0.2MPa-1.0Mpa, which can be adjusted according to the size of the pressed alloy column; the speed ratio of the pulley 13 and the indexing shaft 14 is 1:5-1:1, and the speed ratio of the indexing shaft 14 and the pulley 13 is changed by adjusting the position of the belt on the wheel.

[0025] Among them, the number of indexing tables 7 is 10-20, which is determined according to the size of the workpiece. The indexing shaft 14 rotates one circle, driving the indexing rod 15 and the rotating sleeve 16 to rotate one circle, and the turntable rotates 36°-8°. This makes it easier for the rotating sleeve 16 to move the indexing table 7 and drive the working turntable 6 to rotate.

[0026] like Figure 1-5 As shown, a workpiece base 8 is provided above each indexing table 7, and a drill body 9 is fixedly installed inside the workpiece base 8. Thus, the installation of the drill body 9 is convenient.

[0027] like Figure 1-5 As shown, a mounting hole with an opening facing upward is provided at the center above the carrier 4, a bearing 5 is fixedly installed in the mounting hole, a rotating shaft 17 is fixedly sleeved on the inner ring of the bearing 5, and the upper end of the rotating shaft 17 is fixedly connected to the center of the lower side of the work turntable 6. Thus, the work turntable 6 can be easily rotated above the carrier 4.

[0028] When in use, the drill body 9 is placed on the workpiece base 8, and the motor 12 is turned on. The motor 12 drives the pulley 13 to rotate, thereby driving the indexing shaft 14 connected to the pulley 13 by a belt to rotate, and the indexing shaft 14 drives the indexing rod 15 to rotate, so that the rotating sleeve 16 follows the rotation, and the indexing table 7 is turned to drive the working turntable 6 to rotate, so as to adjust the position of the drill body 9. After the drill body 9 is located directly below the pressure head 11, the column teeth and the pressure head 11 installed at the front end of the hydraulic rod 10 are in the same vertical line. Then the hydraulic rod 10 is started, and the column teeth are pressed into the alloy hole of the drill body 9 to complete a tooth installation operation. Through such a cycle, the tooth installation operation of all alloy columns is completed.

[0029] In summary, the device cooperates with the column pressing device and the dividing device. The dividing device drives the working turntable 6 to rotate through the dividing table 7, so that the drill body 9 on the dividing table 7 is located below the drill bit, and the alloy column tooth installation operation is performed. Therefore, there is no need to repeatedly adjust the drill bit position, which avoids the time-consuming and labor-intensive problems in the pressing process and ensures the tooth fixing effect.
