Description

Technical Field

[0001] This utility model relates to the field of finger joint grinding, and in particular to a finger joint grinding device. Background Technology

[0002] The finger joint cutters currently available on the market are flat rotary cutting tools. These tools have a small number of teeth, with 2-6 alloy teeth on each finger joint cutter. However, these tools wear out quickly and need to be sharpened in a timely manner to maintain their sharpness. We have found that most of the existing grinding equipment is horizontal, which has very high requirements for waterproofing. The spindle is easily damaged by water ingress, and grinding is very inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a finger-joint knife grinding device to solve the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A finger joint grinding device includes a base housing, a grinding assembly, and a finger joint tooth-picking assembly. A support plate is fixedly installed on the upper surface of the base housing, and an mounting plate is fixedly installed on the upper surface of the support plate. A slide table is slidably installed on the front end surface of the mounting plate, and an extension fixing arm is fixedly installed on the front end surface of the slide table. A cylinder is fixedly installed on the extension fixing arm, and a pressure plate is fixedly installed on the telescopic end of the cylinder. The pressure plate fixes the finger joint on the finger joint tooth-picking assembly close to the grinding assembly for grinding.

[0006] Preferably, a guide rail is fixedly mounted on the front end face of the mounting plate, the slide is connected to the guide rail via the slide, a fixing block is fixedly mounted on the slide, a servo motor is fixedly mounted on the upper end face of the mounting plate, and the output end of the servo motor is connected to the fixing block via a lead screw thread.

[0007] Preferably, the bottom of the base box is provided with an inner cavity, in which a mobile collection vehicle is slidably installed.

[0008] Preferably, a universal cooling pipe is installed on the upper surface of the base box, and a waste liquid hole is provided on the upper surface of the base box, which is connected to the empty tank cavity.

[0009] Preferably, a top cover is fixedly installed on the upper surface of the base housing.

[0010] The advantages and positive effects of this utility model are:

[0011] This invention reverses the grinding wheel spindle, resulting in minimal grinding fluid residue on the cutting tool after grinding. The reversed spindle also prevents water ingress during grinding, extending its lifespan. Waste fluid and impurities are collected directly in a collection cart at the bottom, making it very convenient to use. Attached Figure Description

[0024] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0025] Please see Figure 1-6This utility model provides an embodiment of a finger joint grinding device, comprising a base housing 10, a grinding assembly 3, and a finger joint tooth-grinding assembly 4, all covered by a top cover 12. A support plate 13 is fixedly mounted on the upper surface of the base housing 10, and an mounting plate 14 is fixedly mounted on the upper surface of the support plate 13. A slide table 15 is slidably mounted on the front end face of the mounting plate 14, and an extension fixing arm 19 is fixedly mounted on the front end face of the slide table 15. A cylinder 20 is fixedly mounted on the extension fixing arm 19, and a pressure plate 21 is fixedly mounted on the telescopic end of the cylinder 20. The entire finger joint tooth-grinding assembly 4 is fixedly mounted on the slide table 15, and the front end face of the mounting plate 14 is fixedly mounted on... The slide table 15 is connected to the guide rail 16 via the slide table 16. A fixing block 17 is fixedly installed on the slide table 15. A servo motor 18 is fixedly installed on the upper end face of the mounting plate 14. The output end of the servo motor 18 is connected to the fixing block 17 via a lead screw. The finger joint knife 5 to be ground is installed on the fixing plate 41 in the finger joint knife tooth-grinding assembly 4. The pressure plate 21 is positioned directly opposite the fixing plate 41. The pressure plate 21 is pressed onto the finger joint knife 5 for fixing by the drive of the cylinder 20. The servo motor 18 drives the slide table 15 to move up and down for adjustment, bringing the finger joint knife 5 closer to the grinding wheel 32 in the grinding assembly 3 for grinding.

[0026] It should be noted that, in this embodiment, the bottom of the base box 10 is provided with an inner cavity, in which a mobile collection vehicle 11 is slidably installed. At the same time, a universal cooling pipe 22 is installed on the upper surface of the base box 10. The universal cooling pipe 22 is directly connected to the grinding fluid and continuously sprays the grinding fluid onto the grinding area. The upper surface of the base box 10 is provided with a waste liquid hole, which is connected to the cavity. At the same time, the grinding fluid and impurities containing grinding waste fall into the mobile collection vehicle 11 through the waste liquid hole for collection.

[0027] The grinding assembly 3 includes a tool setting rotating seat 34, a locking handle 33, and a tool setting seat 31. When grinding the finger joint tool, the tool setting seat 31 is first rotated out, and the servo motor 18 drives the slide table 15 to move up and down for adjustment. The finger joint tool 5 is brought close to the tool setting seat 31 so that the alloy surface can contact the end faces of the two positioning screw pressure plates 21 at the same time. This position of the alloy surface can be defined as the grinding tooth position. At this time, the locking handle 33 is then turned to lock it, and the tool setting is completed. After the tool setting is completed, the grinding assembly 3 is controlled to move left and right in the horizontal direction to grind the finger joint tool 5.

[0028] The finger joint knife tooth-picking assembly 4 includes a fixed plate 41 and a tooth-picking needle 42, which mainly loads the finger joint knife and performs tooth picking. Each time an alloy tooth is picked, it is ground by a grinding wheel. After grinding an alloy tooth, the cylinder 20 is driven to release the pressure plate 21, and the tooth-picking needle 42 rotates to make the finger joint knife 5 rotate, so that the next alloy tooth moves to the grinding position. The pressure plate 21 then presses down again to continue grinding until all alloy teeth are ground.

[0029] In actual operation, the finger joint 5 to be ground is first installed on the fixed plate 41. After the tool is set by the tool holder 31, the grinding assembly 3 is controlled to move left and right in the horizontal direction to grind the finger joint 5. After grinding one alloy tooth, the cylinder 20 is driven to release the pressure plate 21, and the tooth-pulling pin 42 rotates to move the finger joint 5 to the grinding position, so that the next alloy tooth moves to the grinding position. The pressure plate 21 then presses down to continue grinding until all alloy teeth are ground. During the grinding process, the universal cooling pipe 22 continuously sprays grinding fluid at the grinding area. The grinding fluid and impurities containing grinding waste fall into the mobile collection vehicle 11 through the waste fluid hole for collection. The whole process is very convenient to use, and very little grinding fluid remains on the tool. The grinding wheel spindle is used upside down, which makes it less likely for water to enter and can extend the life of the grinding wheel spindle.

[0030] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
