Description

Technical Field

[0001] The present application relates to the technical field of mechanical processing equipment, and in particular to a drilling tool suitable for drilling a flip plate on a mine-proof seat. Background Art

[0002] The mine-proof seat is equipped with a flip plate, which has a mounting hole for matching with the spring. The opening angle and processing accuracy of the mounting hole will affect the rebound of the seat. Currently, common equipment for drilling holes in the flip plate on the mine-proof seat includes a drilling machine and a drilling fixture. The drilling machine is generally composed of a drill bit, a spindle, a transmission system and a control system. The drilling fixture can clamp and position the flip plate. The drilling fixture generally includes a clamping claw for fixing the workpiece and preventing it from moving or shaking, and a positioning pin or positioning block for ensuring the position of the workpiece. When clamping and positioning the workpiece, it is necessary to adjust the placement of the workpiece relative to the clamping claw and the positioning block, which makes the clamping and positioning operation of the drilling fixture cumbersome during use, affecting the processing efficiency of the parts. After long-term use, the wear of the fixture will bring certain errors and deviations, reducing the processing accuracy of the parts.

[0003] Therefore, it is necessary to propose a new technical solution to solve the problems existing in the prior art. Utility Model Content

[0004] The present application provides a drilling tool for a flip plate, so as to solve the problem that the drilling fixture is inconvenient to operate and use during the processing of the flip plate on the mine-proof seat, resulting in low processing efficiency.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] The present application provides a flip plate drilling tool, comprising a fixed base, a processing table formed on the fixed base, a plurality of positioning columns arranged at intervals on the processing table, the positioning columns and the fixed holes on the flip plate are adapted to each other, and an installation groove for installing a clamping device is arranged between any two adjacent positioning columns, the clamping device comprising an expansion clamping block and two sliding clamping blocks relatively arranged on both sides of the expansion clamping block, the expansion clamping block is an inverted cone-shaped block, and the expansion clamping block moves downward relative to the processing table under the drive of the driving member and forces the two sliding clamping blocks to slide in opposite directions, so that the sliding clamping block and the positioning columns adjacent to it cooperate to lock the flip plate; the expansion clamping block moves upward relative to the processing table under the drive of the driving member, and the sliding clamping block releases the locking state of the flip plate abutting against it.

[0007] Further in the above technical solution, the mounting groove is a long strip groove opened on the processing table, the expansion clamping block is arranged in the middle of the mounting groove, and the two sliding clamping blocks are respectively slidably connected to the mounting groove, and the sliding clamping block slides along the mounting groove under the action of the expansion clamping block.

[0008] Furthermore, two inclined surfaces arranged opposite to each other are formed on the expansion clamping block, one inclined surface is slidably matched with a sliding clamping block, a sliding contact surface matching the inclined surface is formed on the sliding clamping block, and the positioning surface on the sliding clamping block for abutting against the flip plate is a vertical plane.

[0009] Furthermore, a screw is vertically installed at the center of the expansion clamping block, one end of the screw passes through the expansion clamping block and is connected and fixed with a nut, and the other end of the screw is connected to a driving member, which includes a cylinder, and a piston rod of the cylinder is connected to the screw.

[0010] Furthermore, the positioning posts are cylinders perpendicular to the processing table, and a plurality of positioning posts are arranged in one or more rows at equal intervals on the processing table.

[0011] Furthermore, the fixed base includes a horizontally arranged processing table and two vertical plates for supporting the processing table. The two vertical plates are arranged opposite to each other, and a base is arranged at the bottom center of each vertical plate.

[0012] Compared with the prior art, this application has at least the following beneficial effects:

[0013] 1. The flip plate drilling tool provided by the present application comprises a fixed base, a positioning column for mounting a flip plate (the flip plate is the workpiece to be processed) is arranged on the fixed base, and a mounting groove for mounting a clamping device is arranged between two adjacent positioning columns, and the clamping device comprises an expansion clamping block in the shape of an inverted cone, and when the expansion clamping block is driven to move downward, it will gradually squeeze into the middle of the two sliding clamping blocks, forcing the two sliding clamping blocks to slide in opposite directions, and finally the two sliding clamping blocks will move toward the positioning columns opposite to them respectively, and cooperate with the positioning columns to lock the flip plate, complete the clamping and fixing of the workpiece, and ensure the drilling accuracy. After the processing is completed, the expansion clamping block is driven upward by the driving member to release the locking state of the workpiece to remove the workpiece; therefore, the flip plate drilling tool provided by the present application positions and installs the flip plate through the positioning column, and then clamps it by controlling the expansion clamping block to move downward, which is easy to operate and use, and can improve the processing efficiency; in addition, the present application realizes the adjustment of the clamping spacing through the expansion clamping block in the shape of an inverted cone, so it can adapt to flip plates of various sizes, and the tooling has strong adaptability.

[0014] 2. The clamping device in the present application is arranged between two positioning columns, and an expansion clamping block is configured with two sliding clamping blocks. Therefore, driving an expansion clamping block downward can achieve the clamping of two workpieces. Compared with the traditional structure in which one clamping claw fixes one workpiece, the tooling provided in the present application can use fewer clamping devices to achieve effective clamping of more workpieces, thereby improving the utilization rate of the device and saving equipment costs.

[0015] 3. Two inclined surfaces arranged opposite to each other are formed on the expansion clamping block in the present application. The inclination angles of the two inclined surfaces can be the same or different. Each inclined surface is slidably matched with a sliding clamping block. When the expansion clamping block moves downward, the expansion clamping block is slidably matched with the sliding clamping block through the inclined surface thereon and moves downward along the sliding clamping block, forcing the sliding clamping block to slide along the installation groove toward the positioning column, thereby locking the flip plate on the positioning column. This clamping method can avoid clamping errors caused by structural wear. Therefore, the tooling has strong tolerance, long service life and high clamping and positioning accuracy.

[0016] 4. In the present application, the positioning surface on the sliding clamping block used to abut against the flip plate is a vertical plane. The surface contact positioning is not easy to slip, and the pressure at the abutment is evenly dispersed, which is beneficial to improve the reliability of the locking state and ensure the processing accuracy.

[0017] 5. The driving member used to drive the expansion clamping block in the present application may be a hydraulic rod, that is, the present application realizes clamping drive through a hydraulic transmission system to ensure reliable transmission.

[0018] 6. The positioning column in the present application is a cylinder perpendicular to the processing table, and the positioning column is adapted to the fixed hole on the flip plate. When the clamping device presses against the side surface of the workpiece through the end face of the sliding clamping block, even if the workpiece is not installed on the positioning column in the optimal posture, since the positioning column is a cylinder, the sliding clamping block can align the workpiece during the sliding clamping process (the workpiece rotates along the positioning column and is aligned under the action of the sliding clamping block) so that the surface of the workpiece is in contact with the end face of the sliding clamping block. Therefore, when the flip plate drilling tool provided in the present application is used, it is only necessary to install the workpiece on the positioning column, and there is no need to deliberately align the workpiece. The workpiece can be automatically aligned during the clamping process. Therefore, the flip plate drilling tool provided in the present application is easy to operate and use.

[0019] 7. A base is provided at the bottom of the vertical plate of the fixed base in the present application, which not only plays a supporting role, but also can play a role in limiting installation. For example, when the flip plate drilling tooling provided by the present application is installed on a drilling machine and other processing equipment, the base can realize auxiliary positioning installation.

[0029] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0030] In the description of this application: unless otherwise stated, "plurality" means two or more. The terms "including", "comprising", "having" and other expressions in this application also mean "not limited to" (certain units, components, materials, steps, etc.). The terms such as "upper", "lower", "left", "right", "middle" and the like cited in this application are usually for the convenience of intuitive understanding by comparing with the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product. Without departing from the technical concept disclosed in this application, changes in these relative positional relationships should also be regarded as the scope of the description of this application.

[0031] The present application provides a flip plate drilling tool, which is particularly suitable for processing the mounting holes on the flip plate for mounting springs. Figure 1 The flip plate drilling tool includes a fixed base 1, which includes a horizontally arranged processing table 2. A plurality of positioning columns 5 are arranged at intervals on the processing table 2. The positioning columns 5 are used to install the flip plate 9. Therefore, the positioning columns 5 are adapted to the fixing holes at the center of the flip plate 9. An installation groove 6 is arranged between any two adjacent positioning columns 5. A clamping device is installed in the installation groove 6. The clamping device cooperates with the positioning columns 5 to achieve clamping and releasing of the flip plate.

[0032] In this embodiment, see Figure 1 , 5 The clamping device includes an expansion clamping block 7 and two sliding clamping blocks 8 arranged on both sides of the expansion clamping block 7. The expansion clamping block 7 is an inverted cone-shaped block. The expansion clamping block 7 can move downward relative to the processing table 2 under the drive of the driving member and force the two sliding clamping blocks 8 to slide in opposite directions, so that the sliding clamping block 8 and the positioning column 5 adjacent to it cooperate to achieve the locking of the flip plate; when the expansion clamping block 7 moves upward relative to the processing table 2 under the drive of the driving member, the sliding clamping block 8 releases the locking state of the flip plate abutting against it. Therefore, the flip plate drilling tool provided by the present application positions and installs the flip plate through the positioning column 5, and then drives the sliding clamping block 8 to slide horizontally to clamp the workpiece by controlling the expansion clamping block 7 to move downward. It is easy to operate and use. After the processing is completed, the locking state of the workpiece can be released by driving the expansion clamping block 7 to move upward. At this time, the workpiece can be taken out manually or by the clamping device. Therefore, the flip plate drilling tool provided by the present application is easy to operate and use, and can improve the processing efficiency.

[0033] In one embodiment of the present application, see Figure 1 , 4 The mounting groove 6 is a long strip groove formed on the processing table 2, and the two ends of the long strip groove extend toward the two adjacent positioning columns 5, respectively. The mounting groove 6 is centrally arranged between the two adjacent positioning columns 5. Figure 4The expansion clamping block 7 is arranged in the middle of the mounting groove 6, and the two sliding clamping blocks 8 are relatively arranged on both sides of the expansion clamping block 7. The two sliding clamping blocks 8 are respectively slidably connected to the mounting groove 6. The sliding clamping block 8 slides along the mounting groove 6 under the action of the expansion clamping block 7.

[0034] In order to achieve the sliding connection between the sliding clamping block 8 and the mounting groove 6 , a sliding groove adapted to the sliding clamping block 8 may be provided on the bottom or side wall of the mounting groove 6 .

[0035] In practical applications, elastic members may be provided on the sliding clamping block 8 according to requirements, such as a spring being provided horizontally at the bottom of the sliding clamping block 8. When the sliding clamping block 8 is forced to move toward the positioning column 5 to clamp the workpiece, the spring is compressed. When the processing is completed and the expansion clamping block 7 is driven to move upward, the sliding clamping block 8 may move in a direction away from the positioning column 5 under the action of the spring. Of course, when no elastic member is provided, the expansion clamping block 7 is driven to move upward, and the force loaded on the sliding clamping block 8 is also unloaded. At this time, the sliding clamping block 8 does not need to be ejected by the elastic member, and the workpiece can be taken out manually or by a clamping device.

[0036] The clamping device in the present application is arranged between two positioning columns 5, and an expansion clamping block 7 is configured with two sliding clamping blocks 8. Driving an expansion clamping block 7 to move downward can achieve clamping of two workpieces. Compared with the traditional structure in which one clamping claw fixes one workpiece, the tooling provided by the present application can use fewer clamping devices to achieve effective clamping of more workpieces, thereby improving the utilization rate of the device and saving equipment costs. In addition, the present application realizes the adjustment of the clamping spacing through the inverted cone-shaped expansion clamping block 7, so the tooling can adapt to flip plates of various sizes, and the tooling has strong adaptability.

[0037] In one embodiment of the present application, two inclined surfaces arranged opposite to each other are formed on the expansion clamping block 7, one inclined surface is slidably matched with a sliding clamping block 8, and a sliding contact surface matching the inclined surface is formed on the sliding clamping block 8. In the present application, even if wear occurs between the sliding clamping block 8 and the expansion clamping block 7, it will not cause the clamping force of the sliding clamping block 8 on the workpiece to decrease, and it will not cause the sliding clamping block 8 to be difficult to reliably lock the workpiece.

[0038] Two inclined surfaces arranged opposite to each other are formed on the expansion clamping block 7 in the present application. The inclination angles of the two inclined surfaces can be the same or different. Each inclined surface is slidably matched with a sliding clamping block 8. When the expansion clamping block 7 moves downward, the expansion clamping block 7 is slidably matched with the sliding clamping block 8 through the inclined surface thereon and moves downward along the sliding clamping block 8, forcing the sliding clamping block 8 to slide along the mounting groove 6 toward the positioning column 5, thereby locking the flip plate on the positioning column 5. This clamping method can avoid clamping errors caused by structural wear. Therefore, the tooling has strong tolerance, long service life and high clamping and positioning accuracy.

[0039] In one embodiment of the present application, the positioning surface on the sliding clamping block 8 used to abut against the flip plate is a vertical plane. The surface contact positioning is not easy to slip, and the pressure at the abutment is evenly dispersed, which is beneficial to improving the reliability of the locking state and ensuring the processing accuracy.

[0040] In one embodiment of the present application, a screw is vertically installed at the center of the expansion clamping block 7, one end of the screw passes through the expansion clamping block 7 and is connected and fixed with a nut, and the other end of the screw is connected to a driving member, which is a cylinder. The piston rod of the cylinder is connected to the screw, and the screw moves back and forth up and down relative to the processing table under the action of the cylinder.

[0041] In other embodiments, the driving member in the present application may also be a hydraulic rod, and the clamping drive is realized through a hydraulic transmission system to ensure reliable transmission. In practice, the moving speed of the expansion clamping block 7 can be controlled by controlling the speed of the hydraulic rod. Of course, in other specific application examples, the linear driving component used to drive the expansion clamping block 7 to move up and down in the present application may also be other mechanisms, such as a driving electric cylinder, a push rod motor, etc.

[0042] In one embodiment of the present application, the positioning column 5 is a cylinder perpendicular to the processing table 2. When the clamping device presses against the side surface of the workpiece through the end face of the sliding clamping block 8, even if the workpiece is not installed on the positioning column 5 in the optimal posture, since the positioning column 5 is a cylinder, the sliding clamping block 8 can align the workpiece during the sliding clamping process (the workpiece rotates along the positioning column 5 and is aligned under the action of the sliding clamping block 8), so that the surface of the workpiece abuts against the end face of the sliding clamping block 8. Therefore, when the flip plate drilling tool provided by the present application is used, it is only necessary to install the workpiece on the positioning column 5, and there is no need to deliberately align the workpiece. The workpiece can be automatically aligned during the clamping process. Therefore, the flip plate drilling tool provided by the present application is easy to operate and use, and has high positioning accuracy.

[0043] In one embodiment of the present application, a plurality of positioning posts 5 are arranged in one or more rows at equal intervals on the processing table 2. Figure 4 , two rows of positioning columns 5 are arranged on the processing table 2. In a specific application example, the location and quantity of the positioning columns 5 and the clamping devices can be reasonably arranged according to the actual situation of the processing machine tool.

[0044] In one embodiment of the present application, see Figure 1The fixed base 1 includes a horizontally arranged processing table 2 and two vertical plates 3 for supporting the processing table 2. The two vertical plates 3 are arranged opposite to each other. A base 4 is arranged at the bottom center of each vertical plate 3. The base 4 not only plays a supporting role, but also plays a role in limiting installation. For example, when the flip plate drilling tool provided by the present application is installed on a processing equipment such as a drilling machine, the base 4 can realize auxiliary positioning installation. Of course, in a specific application example, in order to install and position the tool and the processing equipment, an extended positioning table or other positioning column 5 pins and other structures can also be set on the column according to actual conditions.

[0045] In summary, the present application provides a flip plate drilling tool. When drilling operation is required on the flip plate, the positioning column 5 and the fixed hole on the flip plate are first used to fit and plug in, so as to fix the flip plate on the fixed base 1, and then the driving member (such as a hydraulic rod) is started to drive the expansion clamping block 7 to move downward. Since the expansion clamping block 7 is in an inverted cone shape, it will gradually squeeze the two sliding clamping blocks 8 on both sides of it, and at the same time force the two sliding clamping blocks 8 to move away from each other, and finally make the two sliding clamping blocks 8 and the adjacent positioning column 5 cooperate to achieve locking of the flip plate. The whole process is simple to operate, which greatly improves the work efficiency and ensures the processing accuracy.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0047] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
