Technical Field
[0001] This utility model relates to the field of cement pipe production technology, and in particular to a cement pipe production end grinding equipment. Background Technology
[0002] During the production of cement pipes, grinding equipment is required to grind the ends of the cement pipes. The grinding quality of the cement pipe ends directly affects their installation sealing, connection strength and service life, and is an indispensable key link in the production process.
[0003] Existing grinding equipment grinds the ends of cement pipes by using a flat grinder to grind the end face of the cement pipe, removing burrs and uneven parts to achieve the required flatness and smoothness for installation. However, this type of grinding equipment is only suitable for grinding the horizontal end face of the cement pipe. The circumferential side and inner circumferential surface of the cement pipe end are curved, and the grinding disc on the flat grinder is not suitable for grinding the curved surface. Furthermore, the grinding roller designed for curved surfaces cannot effectively treat the horizontal end face of the cement pipe. When grinding curved or horizontal surfaces, it is necessary to change the grinding tools, which is quite troublesome.
[0004] Therefore, based on the above situation, it is necessary to design a cement pipe production port grinding equipment to solve the above problems. Utility Model Content
[0005] This invention provides a cement pipe production end grinding device to solve the problems in the prior art.
[0006] The technical problem solved by this utility model is achieved by the following technical solution:
[0007] A cement pipe production end grinding device includes a grinding unit, a drive unit, a handheld operating unit, and a connecting assembly. The grinding unit includes a plate-shaped grinding component for grinding the horizontal end face of the cement pipe and a columnar grinding component for grinding the circumferential sidewall of the cement pipe. The output end of the drive unit is connected to the columnar grinding component and is used to drive the columnar grinding component to rotate along its axial direction. The plate-shaped grinding component is rotatably connected to one end of the handheld operating unit. The drive unit is slidably connected inside the handheld operating unit. The handheld operating unit is provided with an adjusting component for adjusting the sliding position of the drive unit. When the adjusting component drives the columnar grinding component to connect with the plate-shaped grinding component through the connecting assembly, the drive unit can drive the columnar grinding component and the plate-shaped grinding component to rotate synchronously, thereby achieving grinding of the cement pipe end.
[0008] Preferably, the connecting assembly includes a connecting strip disposed on the inner wall of the plate-shaped grinding part and a connecting groove formed on the columnar grinding part, wherein the connecting strip and the connecting groove are adapted to each other.
[0009] Preferably, the adjusting component is an adjusting screw, one end of which is rotatably connected to the driving component, and the other end of which extends to the outside of the handheld operating unit and is threadedly connected to the handheld operating unit.
[0010] Preferably, the handheld operating unit is threaded with a dustproof component, the inner wall of which is threadedly connected to the plate-shaped grinding component, for protecting the gap between the plate-shaped grinding component and the handheld operating unit.
[0011] Preferably, the end face of the columnar grinding component away from the handheld operating unit is provided with a flat grinding surface. When the flat grinding surface of the columnar grinding component is aligned with the grinding surface on the plate-shaped grinding component, it is used to increase the grinding area of the plate-shaped grinding component.
[0012] Preferably, the handheld operating unit is provided with an elastic protective cover.
[0013] The beneficial effects of this utility model are as follows: By setting up a grinding unit, when grinding the circumferential sidewall of the cement pipe, the adjusting component drives the driving component and the columnar grinding component to push out. The driving component drives the columnar grinding component to grind the circumferential sidewall of the cement pipe. When grinding the end face of the cement pipe, the adjusting component drives the columnar grinding component and the plate-shaped grinding component to connect through the connecting component and drive the two to rotate synchronously to grind the end face of the cement pipe. The circumferential sidewall and end face of the port are fully ground. Grinding tools can be quickly switched for different grinding surfaces, improving work efficiency. Attached Figure Description

Detailed Implementation
[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0022] Reference Figures 1-5 As shown, a cement pipe production end grinding device includes a handheld operating unit 3 and a grinding unit 1. The handheld operating unit 3 includes a handheld part 31 for easy gripping and a main body receiving part 32. The grinding unit 1 includes a plate-shaped grinding part 11 for grinding the horizontal end face of the cement pipe and a columnar grinding part 12 for grinding the circumferential sidewall of the cement pipe. In use, for example, grinding the circumferential sidewall of the cement pipe end first requires the use of the columnar grinding part 12. To drive the columnar grinding part 12 to rotate along its axial direction, a driving member 2 is slidably connected inside the main body receiving part 32. The output end of the driving member 2 is connected to the columnar grinding part 12. The driving member 2 can be a motor, which drives the columnar grinding part 12 to rotate. The sidewall of the columnar grinding part 12 contacts and grinds the circumferential sidewall of the cement pipe. To facilitate adjustment of the grinding range of the columnar grinding part 12, the main body receiving part 3... The device 2 is equipped with an adjusting component 4. The adjusting component 4 adjusts the driving component 2 to slide to a suitable position, driving the columnar grinding component 12 to move and thoroughly grind the burrs on the side wall of the cement pipe. Then, the horizontal end face of the cement pipe is ground. To facilitate the grinding of the horizontal end face, a plate-shaped grinding component 11 is used. The plate-shaped grinding component 11 is rotatably connected to the main body receiving part 32. Then, the adjusting component 4 drives the columnar grinding component 12 to move into the main body receiving part 32. When the columnar grinding component 12 contacts the plate-shaped grinding component 11, the two are connected by the connecting component 5. At this time, the driving component 2 drives the columnar grinding component 12 to rotate and simultaneously drives the plate-shaped grinding component 11 to rotate synchronously, thereby achieving the grinding of the horizontal end face of the cement pipe. In the overall operation, both the end face of the cement pipe port and the circumferential side wall of the cement pipe port can be ground, achieving comprehensive grinding of the port and thus improving the quality of the cement pipe.
[0023] Reference Figure 5As shown, furthermore, to achieve the connection between the plate-shaped grinding part 11 and the cylindrical grinding part 12, the connecting assembly 5 includes a connecting strip 51 provided on the inner wall of the plate-shaped grinding part 11 and a connecting groove 52 opened on the cylindrical grinding part 12. The connecting strip 51 and the connecting groove 52 are adapted to each other, wherein the connecting strip 51 is parallel to the central axis of the plate-shaped grinding part 11. When the adjusting member 4 drives the cylindrical grinding part 12 to move into the interior of the main body receiving part 32, the connecting strip 51 enters the interior of the connecting groove 52. In order not to hinder the use of the plate-shaped grinding part 11, the end face of the cylindrical grinding part 12 can be flush with the end face of the plate-shaped grinding part 11. At this time, the driving member 2 can drive the cylindrical grinding part 12 to grind while driving the plate-shaped grinding part 11 to rotate synchronously. This is to perform grinding of the horizontal end face.
[0024] In order to increase the grinding area, the end face of the columnar grinding part 12 is provided with a flat grinding surface. When the flat grinding surface of the columnar grinding part 12 is aligned with the grinding surface on the plate-shaped grinding part 11, it is used to increase the grinding area of the plate-shaped grinding part 11. A larger grinding area means that more areas to be ground can be covered per unit time, reducing the time and number of times required to grind the same area, thereby improving the overall grinding efficiency. Especially for grinding large areas of cement pipe ends, the operation time can be significantly shortened. At this time, the plate-shaped grinding surface can be driven to fit with the end face of the cement pipe to be ground by the hand-held operating unit to carry out the grinding work.
[0025] Reference Figure 3 , Figure 4 As shown, furthermore, to facilitate the adjustment of the sliding position of the drive component 2 within the handheld operating unit 3, the adjusting component 4 is an adjusting screw. One end of the adjusting screw is rotatably connected to the drive component 2, and the other end extends to the outside of the handheld operating unit 3 and is threadedly connected to the handheld operating unit 3. When it is necessary to adjust the position of the cylindrical grinding part 12, the adjusting screw is rotated, and then the adjusting screw drives the drive component 2 to slide, thereby adjusting the position of the cylindrical grinding part 12. The operation is simple and convenient, and the threaded connection has good self-locking performance. After being adjusted to the appropriate position, the adjusting screw can stably maintain the position of the drive component 2, and it is not easy to be displaced due to external force vibration or other factors, ensuring the stability of the position of the cylindrical grinding part 12 during the grinding process, which is beneficial to improving the grinding quality.
[0026] Reference Figures 3-4As shown, furthermore, in order to prevent dust from entering between the plate-shaped grinding part 11 and the handheld operating unit 3 during grinding and affecting the rotation of the plate-shaped grinding part 11, a dustproof part 6 is threadedly connected to the handheld operating unit 3. The inner wall of the dustproof part 6 is threadedly connected to the plate-shaped grinding part 11 to protect the gap between the plate-shaped grinding part 11 and the handheld operating unit 3. When grinding with the columnar grinding part 12, the gap between the plate-shaped grinding part 11 and the handheld operating unit 3 is sealed by the dustproof part 6, thereby preventing dust interference. When grinding with the plate-shaped grinding part 11, the dustproof part 6 can be rotated away from the plate-shaped grinding part 11 to avoid interference with the plate-shaped grinding part 11. Furthermore, the threaded connection between the dustproof part 6 and the plate-shaped grinding part 11 can fix the plate-shaped grinding part 11, preventing the plate-shaped grinding part from rotating arbitrarily when grinding curved surfaces with the columnar grinding part 12.
[0027] Reference Figures 1-4 As shown, in order to reduce the splashing of dust, burrs and other debris during grinding, the handheld operating unit 3 is provided with an elastic protective cover 7 whose inner diameter gradually increases towards the grinding unit 1. The elastic protective cover 7 can be made of materials such as rubber or silicone. When it is inserted into the cement pipe deeply, the elastic protective part may come into contact with the end of the cement pipe or enter the interior of the cement pipe. At this time, the elastic protective part can deform to a certain extent according to the usage conditions to adapt to the usage requirements.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
