Description

Technical Field

[0001] This utility model relates to the field of valve gate casting processing technology, specifically a drilling device for processing valve gate castings with good fixing effect. Background Technology

[0002] Gate valves are among the most commonly used shut-off valves, primarily used to connect or disconnect the medium in a pipeline, but not for regulating the flow rate. They are applicable to a wide range of pressures, temperatures, and diameters, and are especially suitable for medium and large diameter pipelines.

[0003] When drilling holes in valve gate castings, a drilling device is required. However, the drilling device does not effectively fix the valve gate casting, causing it to shake during drilling and resulting in poor drilling results. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drilling device for processing valve gate castings with good fixing effect, which has the advantages of good fixing effect on valve gate castings and solves the problem of poor fixing effect of valve gate castings.

[0005] This utility model discloses a drilling device for machining valve gate castings with good fixing effect, comprising a base, with fixing components on both sides of the top of the base, each fixing component including a movable plate located above the base, sliders on both sides of the bottom of the base, and grooves adapted to the sliders at both ends of the top of the base, toothed plates on both sides of the top of the movable plate, a frame fitted on the surface of the movable plate, the bottom of the frame being fixedly connected to the base, a rotating rod rotatably connected to the inner cavity of the frame, gears fixedly fitted on both sides of the rotating rod, the surfaces of the gears meshing with the toothed plates, a turntable fixedly connected to one end of the rotating rod, a connecting plate fixedly connected to the outer side of the frame, a threaded sleeve fixedly fitted in the inner cavity of the connecting plate, a screw threadedly connected to the inner cavity of the threaded sleeve, a rotating plate on the top of the screw, three equidistant locking holes adapted to the screw being opened on the outer side of the top of the movable plate, and a rotating plate on the inner side of the movable plate. The present invention first places the valve gate casting on the base. Then, rotating the rotating plate causes the screw to rotate, and the screw moves upward through the screw sleeve. When the screw moves out of the locking hole, the turntable can be rotated, causing the rotating rod to rotate. The rotating rod then drives the gear to rotate, which in turn drives the gear plate to move. The gear plate then drives the moving plate to move, which in turn drives the sliding plate on the base to move. The moving plate then drives the clamping plate to move. After the two clamping plates fix the valve gate casting, the rotating plate is reversed. The screw sleeve drives the screw downward, and when the screw moves into the locking hole on the moving plate, it fixes the moving plate. This method provides better fixation of the valve gate casting by the clamping plates on the moving plate, preventing the moving plate from shifting during use and thus ensuring a better fixation effect, which would otherwise result in poor drilling of the valve gate casting.

[0006] This utility model discloses a drilling device for processing valve gate castings with good fixing effect, wherein the other end of the rotating rod is rotatably connected to a movable shaft, and one side of the movable shaft is fixedly connected to the frame.

[0007] The present invention relates to a drilling device for processing valve gate castings with good fixing effect, wherein the surface of the rotating plate is provided with anti-slip threads, and the number of anti-slip threads is not less than fifteen.

[0008] This utility model discloses a drilling device for processing valve gate castings with good fixing effect. One end of the base has an L-plate, and the top of the L-plate has an electric push rod. The output end of the electric push rod passes through and extends into the inner cavity of the L-plate. The output end of the electric push rod has a motor, and the output end of the motor has a drill bit. When drilling is required on the valve gate casting, the electric push rod first operates, driving the motor downwards. The motor then drives the drill bit downwards. When the drill bit contacts the valve gate casting, the valve gate casting can be opened.

[0009] This utility model discloses a drilling device for processing valve gate castings with good fixing effect. The device has support rods fixedly connected to both sides of the inner cavity of the L-plate, and the two support rods are arranged symmetrically about the center of the L-plate. The support rods can increase the support force of the L-plate, thus avoiding the L-plate from shaking during use and thus preventing the components on the L-plate from becoming unstable.

[0010] This utility model discloses a drilling device for processing valve gate castings with good fixing effect. The bottom of the base is provided with an anti-slip pad, and the bottom of the anti-slip pad is provided with anti-slip particles. The anti-slip pad can fix the base, thus making the base more effective in use and avoiding the base from moving during use, which would lead to the instability of the components on the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model first places the valve gate casting on the base. Then, rotating the rotating plate causes the screw to rotate, and the screw moves upward through the screw sleeve. When the screw moves out of the locking hole, the turntable can be rotated, causing the rotating rod to rotate. The rotating rod then drives the gear to rotate, which in turn drives the gear plate to move. The gear plate then drives the moving plate to move, and the sliding groove and slider on the base work together to move the moving plate. The moving plate then drives the clamping plate to move. After the two clamping plates fix the valve gate casting, the rotating plate is reversed. The screw sleeve causes the screw to move downward. When the screw moves into the locking hole on the moving plate, it fixes the moving plate. This method provides better fixation of the valve gate casting by the clamping plate on the moving plate, preventing the moving plate from shifting during use and thus ensuring a better fixation effect, which would otherwise result in poor drilling of the valve gate casting.

[0013] 2. When it is necessary to drill holes in the valve gate casting, the electric push rod first runs, which drives the motor to move downward. At this time, the motor runs and drives the drill bit to move downward. When the drill bit contacts the valve gate casting, the valve gate casting can be opened.

[0014] The support rods can increase the support force on the L-plate, preventing it from shaking during use and thus ensuring the stability of the components on the L-plate.

[0015] The anti-slip pads help to fix the base in place, making it more effective during use and preventing it from shifting, which could lead to instability of the components on the base. Attached Figure Description

[0021] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0022] Please see Figure 1-3This utility model discloses a drilling device for machining valve gate castings with good fixing effect. It includes a base 1, with fixing components 2 on both sides of the top of the base 1. Each fixing component 2 includes a movable plate 201 located above the base 1. Slider blocks 203 are provided on both sides of the bottom of the base 1. Sliding grooves 9, adapted to the sliders 203, are provided at both ends of the top of the base 1. Toothed plates 204 are provided on both sides of the top of the movable plate 201. A frame 205 is fitted onto the surface of the movable plate 201, and the bottom of the frame 205 is fixedly connected to the base 1. A rotating rod 2013 is rotatably connected to the inner cavity of the frame 205. Gears 208 are fixedly fitted on both sides of the surface 3, and the surface of the gears 208 meshes with the toothed plate 204. One end of the rotating rod 2013 is fixedly connected to the turntable 2012. A connecting plate 209 is fixedly connected to the outer side of the frame 205. A threaded sleeve 2011 is fixedly fitted inside the cavity of the connecting plate 209. A screw rod 2014 is threadedly connected to the inner cavity of the threaded sleeve 2011. A rotating plate 2010 is provided on the top of the screw rod 2014. Three locking holes 202 that are adapted to the screw rod 2014 are equally spaced on the outer side of the top of the moving plate 201. A clamping plate 206 is provided on the inner side of the moving plate 201. This utility model first places the valve gate casting... Placed on base 1, rotating the rotating plate 2010 causes the screw 2014 to rotate, which in turn moves the screw sleeve 2011 upwards. When the screw 2014 moves out of the retaining hole 202, the turntable 2012 can be rotated, causing the rotating rod 2013 to rotate. The rotating rod 2013 then drives the gear 208 to rotate, which in turn moves the gear plate 204. The gear plate 204 then moves the moving plate 201, which moves the moving plate 201. The moving plate 201 moves through the sliding groove 9 and the slider 203 on base 1. 1. Move the clamping plate 206. After the two clamping plates 206 fix the valve gate casting, reverse the rotating plate 2010. The screw 2014 can be moved downward through the screw sleeve 2011. When the screw 2014 moves to the locking hole 202 on the moving plate 201, it can fix the moving plate 201. In this way, the clamping plate 206 on the moving plate 201 has a better effect in fixing the valve gate casting, avoiding the movement of the moving plate 201 during use, which would lead to poor fixing effect of the clamping plate 206 on the moving plate 201 on the valve gate casting and poor drilling effect of the valve gate casting.

[0023] The other end of the rotating rod 2013 is rotatably connected to a movable shaft 207, and one side of the movable shaft 207 is fixedly connected to the frame 205.

[0024] The surface of the rotating plate 2010 is provided with anti-slip threads, and the number of anti-slip threads is not less than fifteen.

[0025] An L-plate 5 is provided at one end of the top of the base 1. An electric push rod 6 is provided at the top of the L-plate 5. The output end of the electric push rod 6 passes through and extends into the inner cavity of the L-plate 5. A motor 7 is provided at the output end of the electric push rod 6. A drill bit 8 is provided at the output end of the motor 7. When it is necessary to drill a hole in the valve gate casting, the electric push rod 6 first runs, which drives the motor 7 to move downward. At this time, the motor 7 runs, which drives the drill bit 8 to move downward. When the drill bit 8 contacts the valve gate casting, the valve gate casting can be opened.

[0026] Support rods 4 are fixedly connected to both sides of the inner cavity of L plate 5, and the two support rods 4 are arranged symmetrically about L plate 5. The support rods 4 can increase the support force of L plate 5, and prevent L plate 5 from shaking during use, which would lead to instability of the components on L plate 5.

[0027] The base 1 is provided with an anti-slip pad 3 at the bottom, and the bottom of the anti-slip pad 3 is provided with anti-slip particles. The anti-slip pad 3 can fix the base 1, so that the base 1 is more effective in use and avoids the base 1 from moving during use, which would lead to the instability of the parts on the base 1.

[0028] When using this utility model: First, place the valve gate casting on the base 1. Then, rotate the rotating plate 2010, which drives the screw 2014 to rotate. The screw sleeve 2011 moves upward in cooperation with the screw 2014. When the screw 2014 moves out of the locking hole 202, the turntable 2012 can be rotated. The turntable 2012 drives the rotating rod 2013 to rotate, which in turn drives the gear 208 to rotate. The gear 208 drives the toothed plate 204 to move, which in turn drives the moving plate 201 to move. The sliding groove 9 and the slider 203 on the base 1 cooperate with the moving plate 201 to move. The movement is achieved by moving the clamping plate 206 via the moving plate 201. After the two clamping plates 206 fix the valve gate casting, the rotating plate 2010 is reversed. The screw 2014 is moved downwards via the screw sleeve 2011. When the screw 2014 moves to the locking hole 202 on the moving plate 201, it can fix the moving plate 201. In this way, the clamping plate 206 on the moving plate 201 is more effective in fixing the valve gate casting, avoiding the movement of the moving plate 201 during use, which would lead to poor fixing effect of the clamping plate 206 on the moving plate 201 on the valve gate casting and result in poor drilling effect of the valve gate casting.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
