Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an anti-detachment conversion head structure for a floor grinding machine. Background Technology

[0002] In the field of floor decoration and maintenance, floor grinding machines are the core equipment for achieving fine processing such as floor leveling, polishing, and grinding. As a key intermediary component connecting the main unit of the grinding machine and the grinding disc, the structural stability of the adapter head directly determines the efficiency, accuracy, and safety of the grinding operation. Traditional floor grinding machine adapter heads are mostly installed using adhesive or bolt structures, which have relatively poor reliability and are prone to falling off during construction.

[0003] An existing conversion head structure for a floor grinding robot, such as Chinese patent application number CN202222652232.8, includes a grinding disc, a connecting disc, a fixing disc, and a connector. First, the grinding disc is used to install on the grinding drive part of the floor grinding robot. Unlike the traditional method of fixing the connector with glue, this conversion head structure of the floor grinding robot fixes the connector between the fixing disc and the connecting disc through a mechanical fixing structure, preventing the connector from easily detaching due to heat during grinding. By changing the fixing structure, the probability of detachment due to heat is reduced.

[0004] However, the existing floor grinding machine conversion head structure uses bolts and other structures for installation, and the overall operation requires the use of tools, making it relatively inconvenient to operate.

[0005] Therefore, we propose an anti-detachment conversion head structure for floor grinders to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an anti-detachment conversion head structure for floor grinders, so as to solve the problems mentioned in the background art that the existing floor grinder conversion head structures are relatively complicated to install and operate, and have poor ease of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment conversion head structure for a floor grinder, comprising a conversion head body:

[0008] The upper end of the converter head body has a groove, and a grinding disc is set inside the groove. The lower end of the converter head body has a fixed connector, and the lower end of the grinding disc has a limiting groove. A limiting plate is connected inside the converter head body, and the inner end of the limiting plate extends into the limiting groove.

[0009] The converter head body is equipped with a transmission plate, a transmission block is fixed at the upper end of the transmission plate, a guide groove is opened at the upper end of the transmission block, and a guide connecting rod is fixed on the outside of the limiting plate, the guide connecting rod passes through the guide groove.

[0010] Preferably, a magnet is connected to the inner wall of the groove, the lower end of the grinding disc is attracted to the lower end of the magnet, a positioning groove is provided on the upper end of the conversion head body, and a positioning plate is connected to the lower end of the grinding disc, with the positioning plate engaging with the positioning groove.

[0011] Using the above technical solution, the groove can engage with the grinding disc, and the positioning groove and positioning plate can engage to keep the conversion head body and the grinding disc coaxially rotating. In addition, the design of the magnet can ensure that the grinding disc does not fall off after it is engaged in the groove.

[0012] Preferably, the inner side of the limiting plate is designed with an inclined surface, and the limiting plates are distributed in an equidistant array. The inner end of the limiting plate extends into the groove, and the inner end of the limiting plate is engaged with the limiting groove.

[0013] By adopting the above technical solution, the limiting plate extends into the limiting groove, which can prevent the grinding disc from detaching from the groove, thereby improving the installation stability and reliability of the grinding disc and the conversion head body.

[0014] Preferably, the transmission plate is slidably connected to the inner wall of the conversion head body, and the guide rod is slidably engaged with the guide groove.

[0015] Preferably, the transmission block and the limiting plate are arranged in a ring array with the center of the transmission plate as the axis, and the guide groove is designed with an inclination.

[0016] By adopting the above technical solution, through the cooperation of the guide rod and the guide groove, when the transmission plate and the transmission block are raised and lowered, the guide groove and the guide rod cooperate to drive the limit plate to move horizontally, thereby controlling the engagement state of the limit plate and the limit groove.

[0017] Preferably, the lower end of the converter head body (1) is connected to a first strong magnet (13), and a transmission groove (14) is opened at the bottom of the lower end of the converter head body (1). A three-jaw disk (15) for assembly is provided at the lower end of the converter head body (1). A second strong magnet that matches the first strong magnet (13) is installed at the corresponding position of the three-jaw disk (15).

A strong magnetic block is connected to the top of the stop rod (16), and the strong magnetic block is magnetically connected to the transmission plate (9). A hole is opened at the upper end of the three-jaw disk (15), and the connector (4) engages with the hole.

[0018] Using the above technical solution, the magnetic connection between the converter head body and the three-jaw disk is achieved by the cooperation of the first strong magnet and the second strong magnet. During the connection, the abutment 16 cooperates with the transmission groove, which can limit the change of the connection angle between the three-jaw disk and the converter head body. At the same time, the abutment extends into the transmission groove to push the transmission plate to move.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the anti-detachment conversion head structure for floor grinding machines;

[0020] 1. The adapter head and the grinding disc can be snapped together and installed together with the limiting structure, which can improve the stability and reliability of the installation.

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.

[0031] Please see Figure 1-6 This utility model provides a technical solution: an anti-detachment conversion head structure for a floor grinder, comprising a conversion head body 1, a groove 2 at the upper end of the conversion head body 1, a grinding disc 3 inside the groove 2, a connecting head 4 fixed at the lower end of the conversion head body 1, a magnet connected to the inner wall of the groove 2, the lower end of the grinding disc 3 adsorbing with the lower end face of the magnet, a positioning groove 5 at the upper end of the conversion head body 1, a positioning plate 6 connected to the lower end of the grinding disc 3, and the positioning plate 6 engaging with the positioning groove 5. The connecting head 4 fixed at the lower end of the conversion head body 1 can be used for connecting a drive source. During grinding operations, the grinding disc 3 is engaged inside the groove 2. During connection, the positioning plate 6 engages with the positioning groove 5, maintaining the coaxial rotation of the conversion head body 1 and the grinding disc 3. After the grinding disc 3 engages with the groove 2, the magnet inside the groove 2 magnetically attracts the bottom of the grinding disc 3, preventing the grinding disc 3 from falling off when the conversion head body 1 is connected to the grinding structure.

[0032] A limiting groove 7 is opened at the lower end of the grinding disc 3. A limiting plate 8 is connected inside the conversion head body 1. The inner end of the limiting plate 8 extends into the limiting groove 7. A transmission plate 9 is set inside the conversion head body 1. A transmission block 10 is fixed at the upper end of the transmission plate 9. A guide groove 11 is opened at the upper end of the transmission block 10. A guide connecting rod 12 is fixed on the outer side of the limiting plate 8. The guide connecting rod 12 passes through the guide groove 11. The inner side of the limiting plate 8 is designed with a slope, and the limiting plates 8 are distributed in an equidistant array.

When the grinding disc 3 is engaged and installed in the groove 2, a limiting structure is set to prevent it from falling off during high-speed rotation grinding. The limiting structure is achieved by the engagement of multiple sets of limiting plates 8 with the limiting groove 7. The outer end of the limiting plate 8 is fixed with a guide rod 12, which passes through the inside of the guide groove 11. The inclination of the guide groove 11 can limit the horizontal position of the guide rod 12 and the limiting plate 8. When the position of the guide groove 11 changes, it can synchronously drive the limiting plate 8 to move horizontally, thereby achieving the positioning control of the grinding disc 3.

[0033] The lower end of the converter head body 1 is connected to a first strong magnet 13, and a transmission groove 14 is opened at the bottom of the lower end of the converter head body 1. A three-jaw disk 15 for assembly is set at the lower end of the converter head body 1. A second strong magnet is installed at the corresponding position of the three-jaw disk 15 and the first strong magnet 13. A stop rod 16 is fixed at the upper end of the three-jaw disk 15. The upper end of the stop rod 16 extends into the transmission groove 14. A strong magnetic block is connected to the top of the stop rod 16, and the strong magnetic block is magnetically connected to the transmission plate 9. A hole is opened at the upper end of the three-jaw disk 15, and the connector 4 is engaged with the hole. When it is necessary to install the converter head body 1, the connector 4 is engaged with the hole opened in the three-jaw disk 15. During installation, ensure that the first strong magnet 13 and the second strong magnet are aligned and magnetically attracted to each other.
