DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] See also Figure 1-6 , the present invention provides a variable cross-section vortex backflow blade grinder, comprising a base 1, on which a waste box is arranged;

[0029] The cylindrical grinding unit 2 includes a support plate 20 fixedly arranged on the base 1, a cylindrical grinding wheel 21 arranged on the support plate 20, cylindrical grinding fixtures 22 symmetrically arranged at both ends of the cylindrical grinding wheel 21, and a first driving device 23 for driving the cylindrical grinding wheel 21 close to the cylindrical grinding fixtures 22 on both sides, and the cylindrical grinding wheel 21 is used to perform the first stage of processing on the blade;

[0030] A plane circular grinding unit 3, the plane circular grinding unit 3 comprises a support seat 30 fixedly arranged on the base 1, a plane circular grinding wheel 31 arranged on the support seat 30, a plane circular grinding feeding device 32 movably arranged on the support seat 30, a plane circular grinding fixture 34 driven by a second driving device 33 to perform linear reciprocating motion between the plane circular grinding wheel 31 and the plane circular grinding feeding device 32, and a blade height detection device 35 fixedly arranged on the plane circular grinding unit 3 and used for detecting the height of the blade, the plane circular grinding feeding device 32 is used to provide the product to the clampable position of the plane circular grinding fixture 34, and the plane circular grinding wheel 31 is used to perform the second stage processing on the blade;

[0031] An air knife unit 4, wherein the air knife unit 4 is arranged on one side of the outer cylindrical grinding unit 2;

[0032] The conveying and detecting device 5 includes a six-joint robot 50 arranged on the side of the external cylindrical grinding unit 2, a SCARA robot 51 arranged on the side of the wind knife unit 4, an axis diameter detection fixture 52 movably arranged in the wind knife unit 4, and an axis diameter detection device 53 fixedly arranged on the side of the wind knife unit 4 and used to detect the axis diameter of the product. The six-joint robot 50 is used to convey the blade to the external cylindrical grinding fixture 22 and to convey the blade from the position of the external cylindrical grinding fixture 22 to the position of the axis diameter detection fixture 52. The SCARA robot 51 is used to convey the blade from the axis diameter detection fixture 52 to the plane cylindrical grinding feeding device 32 or the waste box.

[0033] In the above structure, the six-joint robot grabs the blades to be processed and places them on the cylindrical grinding fixtures set on both sides respectively. The first driving device drives the cylindrical grinding wheel to approach the cylindrical grinding fixtures set on both sides, so as to perform the first stage of preliminary processing on the blades clamped by the cylindrical grinding fixtures on both sides. After the cylindrical grinding wheel completes the preliminary processing, the six-joint robot grabs the blades after the preliminary processing to the shaft diameter detection fixture, and then grabs the unprocessed blades to the cylindrical grinding fixture. The blades that have been placed on the shaft diameter detection fixture and processed in the first stage are blown dry by the wind knife unit. The blades and the debris generated by the cylindrical grinding wheel are then inspected by the shaft diameter detection device set on one side of the shaft diameter detection fixture. The qualified blades are transported to the plane cylindrical grinding feeding device position by the SCARA robot, and the unqualified blades are SCARA robot. The CARA robot carries the blade to the scrap bin, and the plane circular grinding feeding device moves the blade to the clamping position of the plane circular grinding fixture. The plane circular grinding fixture clamps the blade and moves it close to the plane circular grinding wheel. It is then processed in the second radial stage by the plane circular grinding wheel. The processed blades are detected by the blade height detection device. Qualified blades are normally output to the variable cross-section eddy current reverse flow blade grinder, and unqualified blades are thrown into the scrap bin. The overall variable cross-section eddy current reverse flow blade grinder integrates an external cylindrical grinding unit, a plane circular grinding unit and a conveying detection mechanism. It can not only load products through an automated conveying device instead of manually placing products to improve accuracy, but also screen out qualified products through integrated automatic size detection, while preventing the need to use multiple machine tools to occupy too much floor space.

[0034] Specifically, the outer cover of the base 1 is provided with a machine tool sheet metal shell shield 10, which can prevent the flying of debris generated during internal processing and grinding, and at the same time protect the operator from contacting the running machine inside, thereby protecting the personal safety of the operator.

[0035] Specifically, the first driving device 23 includes two symmetrically arranged guide rails 230 laterally arranged between the external cylindrical grinding fixtures 22 on both sides, a slider 231 movably arranged on the guide rails 230, a screw rod 232 arranged between the guide rails 230, a nut 233 rotatably arranged on the screw rod 232, and a servo motor 234 arranged on one side of the screw rod 232 and used for driving the screw rod 232 to rotate. The nut 233 and one side of the slider 231 are fixedly connected to the bottom end of the external cylindrical grinding wheel 21. The cooperation of the guide rail and the slider can ensure the high precision and stability of the external cylindrical grinding wheel during movement, and the cooperation of the screw rod and the nut has extremely high transmission accuracy.

[0036] Specifically, the support plate 20 is provided with a guide hole 200 for the movement of the cylindrical grinding wheel 21 , and the guide hole can play a guiding and limiting role in the movement of the cylindrical grinding wheel.

[0037] Specifically, a channel 100 connected to the interior is opened on one side of the sheet metal shell shield 10 of the machine tool, and the channel 100 is used to place a blank material tray 101 with blades. The channel and the blank material tray allow the operator to directly place the blades to be processed from the outside. The overall operation is convenient and simple, allowing the operator to quickly master the machine tool.

[0038] Specifically, an operation panel 102 is provided on the sheet metal housing shield 10 of the machine tool. The digital display of the operation panel can facilitate the operator to observe the operation of the entire grinder more intuitively, thereby reducing the difficulty of operation and the possibility of operation errors.

[0039] Specifically, a water tank 11 and an oil cooler 12 are provided on one side of the base 1, and the water tank and the oil cooler are integrated to reduce the occupied space.

[0040] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
