Detailed Description

The present invention will be described in detail with reference to the following embodiments and drawings.

Referring to fig. 1 and fig. 2, a rotating disc type workbench abrasive belt grinding machine 100 provided by an embodiment of the present invention is shown, including a grinding tool 10 for mounting a workpiece 60, a grinding tool 20, a fixed support 30 and a mobile control assembly 40, where the grinding tool 20 includes a grinding part 21 mounted on the fixed support 30, the grinding tool 10 includes a rotating disc 11, the rotating disc 11 is mounted on the mobile control assembly 40 to be controlled by the mobile control assembly 40, a plurality of grinding stations are circumferentially arranged on the rotating disc 11 for placing the workpiece 60, and the workpiece 60 is sent to a grinding position of the grinding part 21 one by one to be ground by rotating the rotating disc 11.

Specifically, as shown in fig. 3, the plurality of grinding stations of the turntable 11 are a plurality of workpiece support structures arranged along the circumferential direction from the edge of the turntable, each of the workpiece support structures has a profiled groove 12, and the profiled groove 12 has a profile 121 corresponding to the workpiece 60 to support the workpiece 60 and make the workpiece 60 present a surface to be ground to grind the grinding member 21. In the figure, a single blade 61 is shown as an example of a pair of scissors, which lie in the groove 12, with the cutting plane of the scissors facing obliquely upwards, in order to facilitate the cutting of the edges of the scissors.

Further, the groove 12 is a V-groove 12 or a cavity having at least two profiles, for example, both profiles are inclined planes, and the blade plane can be ground regardless of which profile the blade 61 is placed on. Preferably, the two V-shaped profiles facilitate the respective grinding of the respective blade faces of the pair of blades 61, since the scissors are formed by the intersection of two opposing blades 61.

Preferably, the depth of the groove 12 or the cavity is configured to expose the workpiece 60 to the surface to be machined, so that the grinding element 21 can be ground. The grinding member 21 is a sanding belt 21, and a workpiece 60 is ground through the sanding belt 21. The length of the profiled groove 12 or the mould cavity extends in the radial direction of the turntable 11. The grinding action direction (or rotation direction) of the abrasive belt 21 coincides with the tangential direction of the machining point of the turntable 11, i.e. the axial direction of the abrasive belt 21 is parallel to the radial direction of the turntable 11. Through the discovery, when the workpiece 60 on the turntable 11 rotates to the processing station through the rotation of the turntable 11, the extension direction of the surface to be processed of the workpiece 60 is just consistent with the axial direction of the abrasive belt 2, the grinding effect can be fully exerted, and the grinding efficiency is improved.

Further, the fixed bracket 30 includes a support plate 31, a vertical plate 32 and a sliding member 33, the support plate 31 is supported on the sliding member 33 and is provided with a motor 34, the motor 34 is used for driving the grinding tool 20, the sliding member 33 slides up and down along the vertical plate 32, the sliding member 33 includes a sliding plate 35, two sides of the sliding plate 35 are provided with a plurality of sliding ledges 36, and the plurality of sliding ledges 36 are clamped at edges of the vertical plate 32 to guide the sliding member 33 to slide up and down on the vertical plate 32.

As shown in fig. 1 and 2, the grinding tool 20 is connected to the sliding member 33 through a transmission mechanism, the transmission mechanism includes a driving shaft 22 and a driven shaft 23, the abrasive belt 21 is sleeved on the driving shaft and the driven shaft 23, the driving shaft 22 and the driven shaft 23 are respectively installed at the upper end and the lower end of the sliding member 33, the driving shaft 22 is connected to a motor 34, the driving shaft 22 is driven by the motor 34 to rotate so as to drive the grinding member 21 to rotate, the grinding member 21 includes an abrasive belt 21, and the abrasive belt 21 is sleeved on the driving shaft 22 and the driven shaft 23.

In addition, the turntable type workbench abrasive belt grinding machine 100 further comprises a vertical moving part, the vertical moving part comprises a vertical connecting shaft 51, the vertical connecting shaft 51 is installed on the vertical plate 32 and connected with the sliding part 33, and the vertical connecting shaft drives the sliding part 33 to vertically move. The bottom end of the vertical connecting shaft 51 is controlled to extend up and down through a driving piece such as a motor and the like so as to control the up-and-down adjustment of the grinding position of the abrasive belt.

Referring to fig. 4 in conjunction with fig. 1 and 2, the movement control assembly 40 includes left and right moving members including a left and right moving motor 42, a left and right moving guide rail 43, and a left and right moving plate 44, and the left and right moving plate 44 is mounted on the left and right moving guide rail 43 and controlled by the left and right moving motor 42. The left-right moving rail 43 preferably has two sliders or sliding mechanisms 431 below, which are slidably mounted on the two left-right moving rails 43, respectively. The right-left moving plate 44 is controlled by the right-left moving motor 42 to move right and left as indicated by an arrow 401, and the turntable 11 is driven to move right and left. The left and right movement direction is the axis direction of the driven shaft 23 which is the installation axis of the abrasive belt 21.

Further, the turntable 11 is mounted to the left and right moving plate 44 through a rotating shaft, and the rotating shaft is connected to a driving member (e.g., a motor) to drive the turntable 11 to rotate.

Further, for example, the scissor element 61 is disposed with its tip end facing the outside of the turntable 11, and the link end of the scissor element 61 is close to the inside of the turntable 11. Thus, when the tip of the scissor element 61 needs to be deeply machined, the turntable 11 can be moved outward (in a direction away from the sanding belt 21) by the left and right moving members, and the sanding belt 21 grinds only the tip of the scissor element 61. Or in another grinding mode, cutting blade 61 is ground gradually during the outward slow movement, so that the cutting edge of cutting blade 61 becomes thinner gradually from the link end to the tip end. When the front-back position (front-back relative to the feed direction) needs to be adjusted, the adjustment is controlled by moving the motor 46 back and forth in the direction of arrow 402.

Therefore, the above-mentioned rotary table abrasive belt grinding machine 100 can perform machining while rotating by mounting the plurality of workpieces 60 on the rotary table 11, and since the rotary table 11 rotates cyclically, the subsequent workpiece 60 rotates in place immediately after the previous workpiece 60 is machined, and grinding machining is performed between the previous and subsequent workpieces 60 substantially without a break and a gap, the non-machining operation time is shortened greatly, and the machining efficiency is improved greatly. Moreover, the turntable 11 of the turntable-type workbench abrasive belt grinding machine 100 is easy to install, simple and convenient in structure, convenient to operate and control, and capable of providing great convenience for rapid machining, and the machining yield is kept consistent.

It should be noted that the present invention is not limited to the above embodiments, and other changes can be made by those skilled in the art according to the spirit of the present invention, and all the changes made according to the spirit of the present invention should be included in the scope of the present invention.
