Abstract

The grinding wheel dressing and propelling mechanism of the H-shaped steel saw blade sharpening machine has the beneficial effect that the provided grinding wheel dressing and propelling mechanism is a fixing mechanism in a grinding wheel dressing device. The mechanism mainly solves the problem of connection and fixation of the repairing mechanism and the propelling mechanism of the grinding wheel trimming machine device. Through the arrangement of the fixing mechanism, threaded transmission can be formed between the propelling mechanism and the threaded sleeve on the fixing mechanism. When a hand wheel on the fixing mechanism is rotated, the pushing rod can be driven to move forwards or backwards, and then the repairing mechanism installed in the pushing rod is driven. In this way, the grinding wheel can be fed according to the change that the diameter of the grinding wheel is gradually decreased, the grinding wheel dressing continuity is guaranteed, the repairing efficiency of the device is improved, and the workload of workers is reduced. And on the other hand, a bearing, a lining and a hand wheel arranged in the fixing mechanism play a role in supporting and fixing the propelling mechanism and provide a transmission source for forward and backward movement of the propelling mechanism, so that the structure of the whole device is more stable.

Description

Technical Field

[0001] The invention belongs to the field of machine tool processing, and more specifically, relates to a grinding wheel dressing and fixing mechanism of an H-shaped steel saw blade grinding machine. Background Art

[0002] In some industrial production lines, H-shaped steel is cut to length using saw blades during the rolling process. After the saw blade has been used for a period of time, the saw blade will gradually become blunt. This will greatly reduce the cutting efficiency and increase the load on the sawing machine, so the saw blade needs to be sharpened. In the work of sharpening the saw blade, after the grinding wheel for sharpening the saw blade has been used for a period of time, the abrasive grains of the grinding wheel become blunt due to long-term use. The grinding efficiency of the blunt grinding wheel is low and the grinding force becomes larger. For this reason, the saw blade sharpening process requires the repair of the blunt grinding wheel. At present, the method of repairing the saw blade grinding wheel is to repair the grinding wheel with a manual handheld grinding wheel repair block. This repair method has great safety hazards and is likely to cause serious consequences such as hand injuries to the operator. In addition, the control of the angle during the manual repair process is not accurate enough, which may cause errors. Summary of the invention

[0022] like Figure 1-3As shown, a grinding wheel dressing fixing mechanism 01 of an H-shaped steel saw blade dresser of the present application is provided, comprising: an arc plate 02 and a fixing sleeve 03, the arc plate 02 and the fixing sleeve 03 are welded as a whole, and the grinding wheel dressing fixing mechanism 01 of the H-shaped steel saw blade dresser is installed on a housing for installing a grinding wheel dressing device of an H-shaped steel saw blade dresser through the arc plate 02. The fixing sleeve 03 is divided into a clearance fitting section at the left end, a support section in the middle, and a feed section at the right end. The clearance fitting section of the fixing sleeve 03 is formed with a first inner hole 04, and the first inner hole 04 is used to load the propulsion mechanism 05, and the propulsion rod of the propulsion mechanism 05 is formed with a propulsion thread 06. The fixing sleeve 03 forms a clearance fit with the outer diameter of the left end of the propulsion mechanism 05 through the first inner hole 04, and the support section of the fixing sleeve 03 is installed with a bushing 07, and the outer periphery of the support section of the fixing sleeve 03 is formed with a threaded through hole (not shown), and a stop screw (not shown) is installed in the threaded through hole (not shown) to axially fix the bushing 07. The feed section of the fixed sleeve 03 is formed with a second inner hole 08, in which a bearing 09 is installed, and a cap 10 is installed on the right side of the bearing 09, and a threaded section is formed on the right end of the cap 10 for installing and axially locking the bearing 09. The inner ring of the bearing 09 is installed with a push nut 11, and the right end threaded section of the push nut 11 is screwed with a hand wheel 12, and the hand wheel 12 locks the push nut 11 on the inner ring of the bearing 09, and the push nut is sleeved on the outer periphery of the push rod. The arc plate 02 is made of 8mm steel plate, the inner arc radius of the arc plate 02 is 208mm, the height of the arc plate 02 is 218mm, and the width of the arc plate 02 is 168mm. The outer diameter of the fixed sleeve 03 is 124mm, the inner diameter of the clearance fitting section of the fixed sleeve 03 is 114mm, and the inner diameter of the support section of the fixed sleeve 03 is 62mm.

[0023] The fixing mechanism is connected to the housing of the H-shaped steel saw blade grinding machine grinding wheel dressing fixing mechanism 01 by an arc plate. The first inner hole 04 and the bushing 07 of the support section support the propulsion mechanism 05 in the fixing sleeve 03. The second inner hole 08 is equipped with a bearing and a cap is used.

[0024] 10 is axially fixed, a propulsion nut 11 is installed on the inner ring of the bearing 09, and the propulsion nut 11 is locked on the inner ring of the bearing 09 by a hand wheel 12. The propulsion nut 11 on the fixed frame and the propulsion thread 06 form a thread transmission chain. The hand wheel 12 connected to the propulsion nut 11 is rotated, because the bearing 09 is axially fixed, the propulsion nut 11 installed on the bearing 09 is axially fixed, and the rotating propulsion nut 11 will push the propulsion rod of the propulsion mechanism 05 to move forward or backward, achieving the function of fixing and pushing the propulsion mechanism 05. The benefit of the present invention lies in that the fixing mechanism 01 of the designed and manufactured grinding wheel dressing device can better connect and fix the propulsion mechanism 05 of the grinding wheel dressing device, and provide propulsion power for the propulsion processing, meeting the design requirements.

[0025] The outer diameter of the propulsion rod of the propulsion mechanism 05 is 114mm. The length of the bushing 07 is 75mm, and the outer diameter of the bushing 07 is 62mm. The outer diameter of the bearing 09 is 110mm, the inner diameter of the bearing 09 is 60mm, and the length of the bearing 09 is 22mm. The bearing 09 is installed in the second inner hole formed in the feed section to form a transition fit. The outer diameter of the cap 10 is 112mm, the inner diameter of the cap 10 is 100mm, and the length of the cap 10 is 15mm. The inner diameter of the handwheel 12 is 60mm, the outer diameter of the handwheel 12 is 130mm, and the length of the handwheel 12 is 26mm.

[0026] As a further solution, the main function of the fixed sleeve 03 is to be welded as a whole with the arc plate 02 and installed on the cover of the grinding wheel repair. The radius of the inner arc of the arc plate 02 of the H-shaped steel saw blade grinder grinding wheel dressing and fixing mechanism 01 is 208mm, which is the same as the arc plate of the cover, and can fit tightly during welding. The diameter of the middle hole of the arc plate 02 is 114mm, and the size of the first inner hole 04 is 114mm. The arc plate 02 and the first inner hole 04 are of the same size, which can provide radial support to the propulsion mechanism 05 to ensure the stability of the propulsion mechanism 05 when repairing the grinding wheel.

[0027] As a further solution, the first inner hole 04 at the left end of the fixing sleeve 03 and the outer diameter of the left end of the propulsion mechanism 05 form a clearance fit, the maximum clearance is 0.4mm, and the minimum clearance is 0.2mm, so as to support and fix the propulsion mechanism 05 for grinding wheel repair.

[0028] As a further solution, the inner diameter of the support section of the fixed sleeve 03 and the outer diameter of the bushing 07 form a transition fit, the maximum clearance is 0.04mm, and the minimum interference is 0mm. The purpose of installing the bushing 07 in the support section of the fixed sleeve 03 is to provide radial support for the propulsion mechanism 05, restricting the movement and swinging so that the propulsion mechanism 05 can only move axially.

[0029] As a further solution, the outer diameter of the propulsion nut 11 is 60mm, and it is installed in the inner ring of the bearing 09, with a maximum clearance of 0.015mm and a maximum interference of 0mm, forming a transition fit. The axial movement of the bearing 09 is restricted, and the axial movement of the propulsion nut 11 locked in the inner ring of the bearing 09 is also restricted. The bearing 09 also radially restricts the propulsion nut 11. The propulsion nut 11 and the propulsion thread 06 on the propulsion rod of the propulsion mechanism 05 form a threaded transmission chain.

[0030] As a further solution, the handwheel 12 is screwed onto the threaded section at the right end of the propulsion nut 11, and the inner ring of the bearing 09 is locked by the handwheel 12 and the propulsion nut 11 that are screwed together. The propulsion thread 06 on the propulsion nut 11 and the propulsion rod of the propulsion mechanism 05 forms a threaded transmission chain. Rotating the handwheel 12 drives the propulsion nut 06 to rotate together, pushing the propulsion rod of the propulsion mechanism 05 to move, thereby achieving the feeding purpose of the propulsion mechanism 05.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
