Description

Technical Field

[0001] This utility model relates to the field of water ring vacuum pump technology, specifically a water ring vacuum pump body drilling and positioning machine. Background Technology

[0002] A water ring vacuum pump is a type of vacuum pump that uses water as the working medium and forms a water ring through impeller rotation to draw in and expel gas. The pump body requires a drilling machine for processing. Drilling machines can process materials such as metal or wood using high-speed drill bits and are commonly used mechanical equipment.

[0003] Currently, drilling machines still have some shortcomings, such as the pump body moving when the pressure is high.

[0004] To overcome the problem of pump body instability, a prior art Chinese patent (publication number: CN118253813B) discloses a drilling device for pump body processing. This device includes a drilling machine tool with a base plate. The top of the base plate is equipped with a positioning component and a lifting component for fixing and preventing movement of the corrosion-resistant chemical centrifugal pump body. The positioning component includes a limiting component, and the lifting component has a rotating component for flipping the movable positioning shell relative to the fixed positioning shell. By utilizing the combined use of the limiting component, lifting component, and rotating component, the corrosion-resistant chemical centrifugal pump body can be better fixed, preventing displacement during drilling. This improves drilling accuracy and stability and allows for easier flipping of the pump body, enabling faster drilling and increasing drilling efficiency.

[0005] However, the drilling machines currently in use still have certain shortcomings. In the aforementioned document, the drilling machine improves the stability during drilling through the limiting component. However, the position distribution of this device is relatively limited in its effect on fixing the pump body. The pump body is fixed from top to bottom, and the side positioning is relatively weak, which may also affect the accuracy of drilling. Therefore, the existing structure needs to be improved. Utility Model Content

[0006] The purpose of this utility model is to provide a drilling machine for positioning water ring vacuum pump bodies, so as to solve the problem of unstable fixing of the pump body by the drilling machine mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a water ring vacuum pump body drilling positioning drilling machine, including a base, a driving device installed on the top of the base, and a drill rod connected to the bottom end of the driving device.

[0008] The base has two sets of sliding blocks connected by guide blocks inside, and each set of sliding blocks is symmetrically distributed about the center of the base. The bottom ends of the two sets of sliding blocks are not at the same horizontal position. The base is equipped with a rotating mechanism to improve the positioning stability of the drilling machine.

[0009] Furthermore, the rotating mechanism includes a pressing block connected to the side of the sliding block, and a rotating block is rotatably connected inside the base via a bearing. Rotating blocks one are rotatably connected to both ends of the rotating block, and the two rotating blocks one are rotatably connected to the sides of two symmetrical sliding blocks.

[0010] Furthermore, a worm gear is connected to the bottom end of the rotating block, and a worm is meshed with the side of the worm gear, the worm rotating through the inside of the base.

[0011] Furthermore, the inner side of the extrusion block is symmetrically provided with engagement grooves, the inner side of the sliding block is slidably connected with a push block, and the inner side of the sliding block is provided with a positioning mechanism for replacing the extrusion block.

[0012] Furthermore, the positioning mechanism includes two rotating blocks rotatably connected to both sides of the push block, and two locking blocks are rotatably connected to the sides of the two rotating blocks, wherein the locking blocks and the locking grooves are locked together.

[0013] Furthermore, the engaging block and the sliding block form a sliding connection, and a rubber block is rotatably connected to the end of the push block away from the rotating block two. The rubber block is made of rubber, and the rubber block and the irregular block are positioned together. The irregular block is fixed to the side of the sliding block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This water ring vacuum pump body drilling and positioning machine, when using the drilling machine, first place the pump body on the base, then rotate the two worm gears in sequence. The worm gears rotate in the base, driving the worm wheel to mesh and rotate, which in turn causes the rotating block to rotate in the base through the bearing. The rotating block can drive the extrusion block to press the side of the pump body, first fixing the symmetrical plane, and then rotating another set of worm gears to fix the other two sides of the pump body with the extrusion block. It is suitable for pump bodies of different shapes, prevents drilling deviation, and improves accuracy.

[0016] 2. Equipped with sliding blocks, the four sets of extrusion blocks can be moved by sliding blocks of different lengths, thereby extruding and fixing the pump body in different directions, improving the stability of the pump body during processing.

[0017] 3. It is equipped with a worm gear and a worm. The meshing rotation of the worm gear and the worm has a self-locking effect, which can further improve the stability when the extrusion block is fixed to the pump body and improve the accuracy of the pump body machining.

[0018] 4. It is equipped with rubber blocks, which can be squeezed into the irregularly shaped blocks by their own material, thereby driving the locking blocks to efficiently disassemble and assemble the extrusion blocks, improving the practicality of the drilling machine.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1, such as Figures 1-5The present invention provides the following technical solution to address the problem of unstable pump body fixation in drilling machines: a rotating mechanism is disclosed, comprising a base 1, a drive device 2 mounted on the top of the base 1, and a drill rod 3 connected to the bottom of the drive device 2. Two sets of sliding blocks 101 are slidably connected inside the base 1 via guide blocks, and each set of sliding blocks 101 is symmetrically distributed about the center of the base 1, with the bottom ends of the two sets of sliding blocks 101 not at the same horizontal position. A rotating mechanism to improve the positioning stability of the drilling machine is provided inside the base 1. The rotating mechanism includes a pressing block 102 connected to the side of the sliding block 101. A rotating block 103 is rotatably connected inside the base 1 via bearings. Rotating blocks 104 are rotatably connected to both ends of the rotating block 103, and the two rotating blocks 104 are rotatably connected to the sides of the two symmetrical sliding blocks 101. A worm gear 105 is connected to the bottom of the rotating block 103, and a worm 106 is meshed with the side of the worm gear 105, rotating through the base 1.

[0030] When using the drilling machine, place the pump body on the upper surface of the base 1, and then rotate the two worm gears 106 sequentially. The worm gears 106 rotate within the base 1, driving the worm wheel 105 to mesh and rotate. The worm wheel 105, in turn, drives the rotating block 103 to rotate. The rotating block 103 rotates within the base 1 via bearings. This rotation of the rotating block 103 moves two sets of rotating blocks 104, which in turn pull the sliding block 101. The sliding block 101, in turn, allows for... The guide block guides the sliding block 101 inside the base 1. During the sliding process of the sliding block 101, the rotating block 104 can rotate with the sliding block 101 through the rotating block 103. When the sliding block 101 slides, it can drive the extrusion block 102 to move to the side of the pump body for extrusion. When the pump body is extruded, the symmetrical plane is fixed. Then, another set of worm gears 106 is rotated. The other set of worm gears 106 can drive the extrusion block 102 to extrude on the other two sides of the pump body. This can fix and extrude pump bodies of different shapes, prevent the pump body from shifting during drilling, and improve the drilling accuracy.

[0031] Example 2, as follows Figures 6-8The present invention provides the following technical solution to address the problem of inconvenient replacement of the extrusion block 102 of the drilling machine. Based on Embodiment 1, a positioning mechanism is disclosed: symmetrical engagement grooves 201 are provided on the inner side of the extrusion block 102; a push block 202 is slidably connected through the inner side of the sliding block 101; a positioning mechanism for replacing the extrusion block 102 is provided on the inner side of the sliding block 101; the positioning mechanism includes rotating blocks 203 rotatably connected to both sides of the push block 202; engagement blocks 204 are rotatably connected to the sides of the two rotating blocks 203; the engagement blocks 204 are engaged with the engagement grooves 201; the engagement blocks 204 and the sliding block 101 are slidably connected; and a rubber block 205 is rotatably connected to the end of the push block 202 away from the rotating blocks 203; the rubber block 205 is made of rubber; the rubber block 205 is positioned with the irregular block 206; and the irregular block 206 is fixed to the side of the sliding block 101.

[0032] When the extrusion block 102 of the drilling machine wears out, the rubber block 205 can be rotated. When the rubber block 205 rotates, it can rotate at the end of the push block 202. The rotation of the rubber block 205 can extrude into the inner wall of the shaped block 206. During extrusion, the rubber block 205 deforms due to its own rubber material. When deformed, the rubber block 205 can rotate out of the shaped block 206, at which point the push block 202 can be pulled. When the push block 202 is pulled, it can slide inside the sliding block 101. The sliding of the push block 202 can pull the two rotating blocks 203 to move. When the rotating block 203 moves, it can drive the two locking blocks 204 to move. During the process, the rotating block 203 can rotate with the locking block 204 through the push block 202. When the locking block 204 moves, it can slide inside the locking groove 201 and the sliding block 101. When the locking block 204 slides out of the locking groove 201, the pressing block 102 moves. When the pressing block 102 moves, it can move out of the side of the sliding block 101, thereby realizing the disassembly of the pressing block 102. After the pressing block 102 is disassembled, it can be replaced with a new one, which improves the replacement efficiency of worn parts of the drilling machine and improves the practicality of the device.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
