Description

Technical Field

[0001] The invention belongs to the technical field of curved saw processing grinders, in particular to a fixed arc curved saw processing grinder. Background Art

[0002] The structure of a processing grinder for fixed arc curved saws is as follows: it includes a bed, a platform capable of horizontal movement is arranged on the bed, and a curved saw clamping mechanism is arranged on the platform. A grinding wheel mechanism is arranged in front of the horizontal movement platform, and the grinding wheel mechanism can be rotated and adjusted in the horizontal plane, and can also be adjusted horizontally in the front and rear directions. Here, each adjustment direction is defined, wherein the direction that drives the curved saw clamping mechanism to move horizontally is the X-axis direction, the direction that drives the grinding wheel mechanism to rotate and adjust in the horizontal plane is the A-axis direction, the swing of the grinding wheel mechanism in the longitudinal space is the Y-axis direction, and the overall front and rear direction adjustment of the grinding wheel mechanism is the Z-axis direction.

[0003] Since the grinding wheel will also move when the A-axis swings to the corresponding saw blade rake angle, on the other hand, the saw blade circle will change its center as the X-axis moves. The problem with existing processing grinders is that when the A-axis and the Y-axis are set to the corresponding angles, the relative positions of the X-axis and the Z-axis need to be calculated, which involves the addition and subtraction of two trigonometric function values. Such calculations need to be performed when processing each saw tooth, which requires a large amount of calculations, puts higher requirements on software programming, and increases the difficulty of later debugging.

[0023] The present invention is further described below in conjunction with specific embodiments.

[0024] like Figure 1-Figure 3 As shown, the present invention discloses a fixed arc curved saw processing grinder, comprising a bed 1, on which a grinding head mechanism 9 and a curved saw clamping mechanism are arranged. The curved saw clamping mechanism is driven by a driving mechanism and can move along a circular arc on the bed, and the grinding head mechanism 9 can swing in the longitudinal space to adjust the angle.

[0025] In one embodiment, a circular arc guide rail 2 is provided on the bed, a swing seat 3 is mounted on the circular arc guide rail 2, and the inner end of the swing seat 3 is connected to the first driving rotary motor 13. The swing seat is mainly driven by the first driving rotary motor to move along the circular arc guide rail, and cooperates with the grinding wheel mechanism to process each saw tooth of the curved saw.

[0026] In one embodiment, a first transverse guide rail 4 arranged in the front-to-back direction is provided at the upper end of the swing seat 3, and the first transverse guide rail 4 is connected to the bending saw clamping mechanism through a slider 5 and a bracket 6. The front-to-back position can be moved and adjusted, which is convenient for manually adjusting the calibration center of saw blades with different radii before processing.

[0027] In one embodiment, a base 18 is further provided on the bed, a combined adjustment block 12 is provided on the base, a second transverse guide rail is provided on the combined adjustment block, a slider driven by a transverse motor is connected to the second transverse guide rail, and the slider is connected to the grinding wheel mechanism mounting seat 11. The front and rear positions of the grinding wheel mechanism mounting seat can also be adjusted to cooperate with different saw blades for processing.

[0028] Specifically, the grinding wheel mechanism mounting seat 11 is connected to the grinding wheel 10 via a swing mechanism. The grinding wheel can be driven by the swing mechanism to swing and adjust the angle in the longitudinal space, that is, in the Y-axis direction.

[0029] In one embodiment, the combined adjustment block includes a bottom block 17, on which a middle block 16 is arranged, and the left and right positions of the middle block 16 can be adjusted by the side adjustment screws 14. The middle block has a limit slot at the bottom of the center position, and a limit block is arranged at the corresponding limit slot of the bottom block. The left and right positions of the middle block are adjusted by adjusting the screws 14, so as to manually adjust the offset compensation of the grinding head caused by different radii when swinging the forward tilt angle.

[0030] Specifically, a top block 15 is arranged on the upper part of the middle block, and an arc groove 19 is provided on the top block. A positioning hole 20 is provided on the middle block 16 at a position corresponding to the arc groove 19, and a fastener is inserted into the arc groove to position the top block. This structure can adjust the offset angle of the top block relative to the middle block, so as to manually adjust the forward inclination angle of different saw blades.

[0031] In one embodiment, the curved saw clamping mechanism includes a base 21, a saw blade positioning platform 7 is disposed on the base 21, and a pressing mechanism 8 is disposed outside the saw blade positioning platform 7. After the saw blade is placed on the positioning platform, the pressing mechanism presses the entire surface and positions it in the longitudinal direction.

[0032] Specifically, a plurality of adjustable positioning push blocks 23 are arranged in the front-rear direction on the saw blade positioning platform 7. A plurality of empty slots are opened on the saw blade positioning platform, and limit blocks are installed in the empty slots. The rear of the limit blocks is slotted, and the push-out position of the limit blocks is limited by fasteners in the slots so as to match the arc at the rear end of the saw blade.

[0033] Specifically, the saw blade positioning platform 7 is provided with a side positioning block 24 on the side. According to the length of the saw blade, the position of the side positioning block is adjusted so as to reliably position the side of the saw blade.

[0034] The processing process of the present invention is as follows: before processing, the saw blade 22 is placed on the saw blade positioning platform, the positioning push block and the side positioning block are adjusted to match the saw blade, and then the pressing mechanism is started to reliably press and fix the saw blade. After that, the front and rear positions of the grinding wheel mechanism mounting seat and the bending saw clamping mechanism are adjusted to facilitate manual adjustment of the calibration center of saw blades with different radii before processing. The position of the combined adjustment block can also be adjusted as needed, and the saw blade rake angle can be manually adjusted, and the offset compensation of the grinding head caused by different radii when swinging the rake angle can also be manually adjusted.

[0035] During formal processing, the grinding wheel mechanism swings to the appropriate Y-axis angle to process the positive and negative teeth. The swing seat only needs to rotate one tooth position according to the circular arc guide to process the second tooth.

[0036] In the present invention, the bending saw clamping mechanism is arranged on a section of circular arc guide rail, so that the workpiece to be processed can move along a predetermined circular arc track, and the workpiece is cocentric with the clamping mechanism that drives it to swing, which is convenient for the grinding head to process the saw blade, simplifying the programming difficulty and the work of later debugging.
