Description

Technical Field

[0001] The invention relates to a milling device, in particular to a carbon felt cylinder outer peripheral surface equal-diameter vertical milling device, belonging to the field of thermal insulation material processing equipment. Background Art

[0002] The carbon felt cylinder used for thermal insulation equipment often has bulges and depressions on its outer circumference due to various reasons such as materials, equipment, and process during production, which not only affects the appearance of the product, but also affects the installation with the thermal insulation equipment in serious cases. The existing technology usually places the carbon felt cylinder horizontally on the frame, rotates the carbon felt cylinder, and uses a milling cutter to mill the outer circumference of the cylinder in order to achieve the effect of cutting it into a perfect circle. This horizontal processing is divided into internal support horizontal processing and wheel pad horizontal processing.

[0003] The internal support type horizontal processing is to use a number of equal diameter support legs installed on the internal support shaft to support the carbon felt cylinder inside the cylinder. For a type of larger and longer cylinder, its weight always causes the internal support shaft to deform. When rotating, the middle part of the cylinder makes a non-concentric rotation, making the cylinder rotate and show swinging and ups and downs. Obviously, it is difficult to obtain ideal processing accuracy.

[0004] The wheel-type horizontal processing is to place the carbon felt cylinder horizontally on two wheel treads arranged side by side, and use the wheel to drive the carbon felt cylinder to rotate on the wheel tread to perform milling of the outer peripheral surface. Since the carbon felt cylinder has convex and concave surfaces, it will cause the carbon felt cylinder to fluctuate when rolling on the wheel tread, making it difficult to obtain ideal processing accuracy.

[0005] At the same time, the large carbon felt cylinder itself is very heavy. When there is no internal support in the cylinder or the support point matrix is ​​sparse, it is difficult for the horizontally placed cylinder to maintain its inherent shape when it rotates. The diameter of the same part will continue to change during continuous rotation, so it is also impossible to obtain the ideal processing effect. Summary of the invention

[0006] The technical problem to be solved by the present invention is mainly: the technical problem to be solved by the present invention is: when horizontal rotation is adopted, the carbon felt cylinder cannot be rotated around the axis center line, and is greatly affected by its own weight, and its own diameter keeps changing during rotation, so it is difficult to obtain the ideal processing effect of milling the outer peripheral surface of the carbon felt cylinder.

[0037] The present invention is described in detail below with reference to the embodiments and accompanying drawings:

[0038] like Figure 1 , 2As shown in Figures 3, 8 and 15, a device 10 for vertically milling the outer circumference of a carbon felt cylinder 1 with equal diameters comprises a self-centering carrier plate 3, a vertical propulsion frame 4 and a vertical sliding tool holder 5; the self-centering carrier plate 3 comprises a rotating chassis 31 arranged on the ground and a self-centering device arranged on the rotating chassis 31; the vertical propulsion frame 4 is arranged outside the self-centering carrier plate 3 and can be horizontally pushed forward toward the self-centering carrier plate 3; the vertical sliding tool holder 5 is arranged on a side of the vertical propulsion frame 4 facing the self-centering carrier plate 3, can slide up and down along the vertical propulsion frame, and is provided with a motor 54 and a milling cutter 55 connected to the output shaft of the motor, and the milling cutter 55 extends from the vertical propulsion frame 4 to the upper area of ​​the edge of the centering carrier plate 3. The application principle is: place the carbon felt cylinder 1 to be processed on the self-centering carrier 3, operate the self-centering carrier 3 to make the axis of the carbon felt cylinder 1 at the center of the self-centering carrier 3 (this is only relative, it is impossible to achieve absolute centering), rotate the self-centering carrier 3 to make the carbon felt cylinder 1 rotate around its own axis; turn on the milling cutter motor to make the milling cutter rotate at high speed; determine the entry height of the milling cutter on the cylinder, and make the milling cutter stop at a certain height by sliding the sliding cutter seat 5 upward or downward on the vertical push frame 4; determine the entry depth, and implement equal-diameter milling on the carbon felt cylinder 1 by appropriately pushing the vertical push frame 4; gradually move the sliding cutter seat 5 upward or downward to achieve equal-diameter milling of the entire cylinder outer surface. The following two points need to be explained here:

[0039] 1. Between the milling cutter 55 and the motor 54 is a tool bar with a certain length. Since the vertical push frame 4 cannot enter the area directly above the self-centering carrier plate 3, a tool bar with a certain length can be inserted, so as to adapt to the change in the size of the carbon felt cylinder 1.

[0040] 2. The lower end of the carbon felt cylinder 1 that needs to be milled has a perfect circular steel liner 8 (also called an inner mold in the industry), and the bottom end of the steel liner 8 has a flange-shaped gasket 81. The outer diameter of the flange-shaped gasket 81 is larger than the inner diameter of the carbon felt cylinder 1 but smaller than the outer diameter of the carbon felt cylinder 1. The flange-shaped gasket 81 has a certain thickness, so that the bottom edge of the carbon felt cylinder 1 placed on the self-centering carrier 3 is actually a certain distance away from the disk surface of the self-centering carrier 3. Therefore, the milling cutter 55 can completely mill the bottom edge of the carbon felt cylinder 1 without worrying about damaging the self-centering carrier 3.

[0041] It can be seen from the above-mentioned settings and their application principles that the carbon felt cylinder 1 placed on the self-centering carrier plate 3 will not be affected by gravity and will not change its inherent diameter size at all; by setting the self-centering carrier plate 3, the axis line of the carbon felt cylinder 1 can be accurately placed at the center of the self-centering carrier plate 3, so that the carbon felt cylinder 1 can rotate around the common axis line of itself and the self-centering carrier plate 3 when rotating with the self-centering carrier plate 3, and the outer surface of the carbon felt cylinder 1 can be accurately milled, thereby obtaining a carbon felt cylinder 1 product with a perfect circle as the outer circumference.

[0042] Here are some further improvements:

[0043] like Figure 2 , 3 As shown in , 4, the upper surface of the rotating chassis 31 of the self-centering carrier 3 is set as a horizontal plane; the self-centering device includes a cross-shaped sliding disk 32 that can slide on the rotating chassis 31 and a centering seat 33 that is arranged on the rotating chassis 31 and can slide radially; the cross-shaped sliding disk 32 has four petals 321 distributed in a cross shape, and there is a spacing between the petals 321, forming four petal gaps 322 distributed in a cross shape; as a preferred sliding method, a sliding ball that can slide in any direction is arranged under the petal 321. There are four centering seats 33, which are respectively located in the four petal notches 322 of the self-centering carrier 3. The centering seats 33 located in the petal notches 322 are spaced apart from the cross-shaped sliding plate 32, and this spacing is the maximum sliding distance of the cross-shaped sliding plate 32 on the rotating chassis 31; the centering seats 33 include vertically arranged enclosures 331, the height of the enclosures is higher than the height of the petals 321, and the raised parts thereof are used to contact, push and restrict the carbon felt cylinder 1; the upper surface of the cross-shaped sliding plate 32 is flat and always remains in a horizontal state. Obviously, this is to keep the carbon felt cylinder 1 placed on the cross-shaped sliding plate 32 in a vertical state.

[0044] The self-centering carrier 3 also includes a centripetal slide rail 34 arranged on the rotating chassis 31 below the four petals 322 of the cross-shaped slide plate 32, and a centripetal screw 35 is arranged in the centripetal slide rail 34. Each centripetal screw 35 is coupled through a conical tooth 352 arranged at the end in the center area of ​​the self-centering carrier 3, so that each centripetal screw 35 can rotate synchronously and with equal propulsion. The four centripetal seats 33 are respectively mounted on these four centripetal screws 35 and are always on the same circle with the center of the self-centering carrier 3 as the center. A centripetal crank 351 is arranged at the outer end of any centripetal screw 35, and the crank on the centripetal crank 351 can be retracted to prevent the crank from hitting the vertical propulsion frame 4 when the self-centering carrier 3 rotates.

[0045] With the above arrangement, the centering clamp 33 can gradually push the misaligned carbon felt cylinder 1 together with the cross-shaped sliding disk 32 toward the center of the disk by simply shaking the centering crank handle 351; when the centering crank handle 351 cannot be shaken, the four centering clamps 33 have already contacted and enclosed the carbon felt cylinder 1, proving that the carbon felt cylinder 1 has been aligned with the self-centering carrier 3.

[0046] like Figure 5 , 6As shown in Figures 7 and 8, the centering socket 33 also includes a push sleeve 36, and the outer peripheral surface of the push sleeve 36 is provided with an annular groove 361; an arc surface groove 332 matching the outer peripheral arc surface of the push sleeve 36 is provided below the centering socket 33, and pins 333 that can be inserted into the annular grooves 361 on both sides of the outer periphery of the push sleeve 36 are provided on both sides of the arc surface groove 332, and the outer surface of the pin 333 is matched with the inner groove surface of the annular groove 361, and a screw through hole 334 is provided on the pin 333, and the centering socket 33 is fastened to the matching push sleeve 36 by screwing a screw into the screw through hole 334.

[0047] Due to the restriction of the centripetal slide rail 34, the centering seat 33 cannot rotate around the centripetal screw 35. Therefore, when a centering seat 33 is not on the same circle as other centering seats 33 and needs to be slightly adjusted forward or backward, the above setting is needed to solve it, that is, unscrew the screw, pull the pin 333 of the centering seat 33 upward from the annular groove 361 of the push sleeve 36, then rotate the push sleeve 36 forward or backward to make radial fine adjustment, and then install the centering seat 33.

[0048] like Figure 8 As shown, the vertical propulsion frame 4 includes an upper seat plate 41, a lower seat plate 42, a sliding column 43, a left vertical screw 44 and a right vertical screw 45; the upper seat plate 41 and the lower seat plate 42 are both triangular, the left vertical screw 44 is fixed at the left front corner between the upper seat plate 41 and the lower seat plate 42, the right vertical screw 45 is fixed at the right front corner between the upper seat plate 41 and the lower seat plate 42, and a horizontal coupling rod 46 is provided between the left vertical screw 44 and the right vertical screw 45 on the lower seat plate 42, and the left vertical screw 44 and the right vertical screw 45 are synchronously and equally coupled and rotated by the conical teeth at both ends of the horizontal coupling rod 46 and the conical teeth at the lower ends of the left vertical screw 44 and the right vertical screw 45, and a lifting motor 47 coupled to the right vertical screw 45 is provided at the upper end of the right vertical screw 45. The slide post 43 is fixed at a rear angle between the upper seat plate 41 and the lower seat plate 42 .

[0049] In the above arrangement, the left vertical screw rod 44 and the right vertical screw rod 45 are used to push the vertical sliding knife seat 5 upward or downward. The provision of two such screw rods is more conducive to lifting and lowering the vertical sliding knife seat 5 in a balanced manner. The function of the slide column 43 is also to balance and stabilize the vertical sliding knife seat 5. In the above arrangement, the lifting motor 47 can also be arranged at the upper end of the left vertical screw rod 44, and the horizontal coupling rod 46 can also be arranged on the lower bottom surface of the upper seat plate 41 and coupled to the upper ends of the left vertical screw rod 44 and the right vertical screw rod 45. Through the above arrangement, the left vertical screw rod 44 and the right vertical screw rod 45 can be rotated synchronously by simply starting the lifting motor 47, so as to control the lifting or lowering of the sliding knife seat 5 and the lifting or lowering speed of the sliding knife seat 5.

[0050] like Figure 8 , 9 As shown, the vertical milling device 10 also includes a base frame 2 for installing a vertical propulsion frame 4, which has a top side 21, a bottom side 22, and a column 23 arranged between the rear ends of the top side 21 and the rear ends of the bottom side 22. The top side 21, the column 23, and the bottom side 22 form a propulsion space 24 for the vertical propulsion frame 4 that opens forward; the vertical propulsion frame 4 is installed in the propulsion space 24 and can slide back and forth in the propulsion space 24. The base frame 2 needs to be very stable and cannot shake beyond the design range in the working state. Therefore, a diagonal brace 213 is also provided at the rear of the vertical propulsion frame 4, and a reinforcing plate 211 and a ground-mounted diagonal brace plate 212 fixed to the reinforcing plate 211 are provided on one side of the top side 21.

[0051] The base frame 2 also has a base plate 26 fixed on the ground, and the lower ends of the above-mentioned columns 23, bottom 22, diagonal braces 213 and ground-mounted diagonal brace plates 212 are all fixed on the base plate 26; the base plate 26 is also provided with waist-shaped bolt holes 261, whose function is to change the fixed position of the base frame 2 forward or backward according to the size of the carbon felt cylinder 1.

[0052] The bottom surface of the top square 21 of the base frame 2 is provided with a concave arc track groove 25 opening downward, and the top surface of the bottom square 22 is provided with a concave arc track groove 25 opening upward; the top surface of the upper seat plate 41 of the vertical propulsion frame 4 and the bottom surface of the lower seat plate 42 are provided with a tubular slide 48, and the outer peripheral surface of the tubular slide 48 cooperates with the concave arc surface of the concave arc track groove 25. The vertical propulsion frame 4 installed in the propulsion space 24 can slide back and forth in the propulsion space 24 by the tubular slides 48 on the top and bottom of the frame respectively cooperating with the concave arc track grooves 25 on the upper and lower parts of the base frame.

[0053] like Figure 8 As shown in FIG. 12, a forward screw rod 62 is provided below the top 21 and above the bottom 22 of the base frame 2, and a forward propulsion tube 63 is sleeved on the upper and lower forward screw rods 62, and the upper forward propulsion tube 63 and the lower forward propulsion tube 63 are respectively connected to the tubular slide 48 above and the tubular slide 48 below the vertical propulsion frame 4; a vertical coupling rod 6 is provided in the column 23 of the base frame 2, and the upper and lower ends of the vertical coupling rod 6 are respectively coupled with the upper and lower forward screw rods 62 through conical teeth, so that the upper and lower forward screw rods 62 can rotate synchronously and with equal propulsion; the vertical coupling rod 6 is provided with a coupling crank 61 coupled through conical teeth. Through the above arrangement, the vertical propulsion frame 4 can be smoothly pushed forward or backward by just shaking the coupling crank 61.

[0054] The tubular slide 48 has a tubular cavity 481, and the front end of the forward screw 62 extends into the tubular cavity 481; the outer peripheral surface of the forward propulsion tube 63 is provided with an annular fixing groove 631, and the left and right sides of the rear end of the tubular slide 48 are provided with connecting pieces 482, and the connecting pieces 482 are provided with threaded through holes 483. The connecting pieces 482 on both sides of the tubular slide 48 are clamped on the tubular slide 48, and the screws 484 screwed in through the threaded through holes 483 are just inserted into the annular fixing groove 631. This arrangement is also to enable the forward propulsion tube 63 to be adjusted forward or backward alone after the screws 484 are removed, so as to ensure that the left vertical screw 44 and the right vertical screw 45 of the vertical propulsion frame 4 are always perpendicular to the horizontal plane.

[0055] The annular fixing groove 631 is a trapezoidal groove, and the end surface of the screw 484 is a conical surface that matches the inner groove surface of the annular fixing groove 631. This makes it easier for the screw 484 to be screwed into the annular fixing groove 631.

[0056] like Figure 8 , 13 As shown, the sliding knife seat 5 has two triangular wing-shaped guide holes 51, which are fixed by two left and right side plates 52. The upper and lower guide holes 51 and the left and right side plates 52 enclose a motor installation space 53; the left front corners of the upper and lower guide holes 51 are respectively provided with left thrust holes 511 sleeved on the left vertical screw rod 44, the right front corners of the upper and lower guide holes 51 are respectively provided with right thrust holes 512 sleeved on the right vertical screw rod 45, and the rear parts of the upper and lower guide holes 51 are respectively provided with stabilizing holes 513 sleeved on the sliding column 43. Such a setting is stable and simple, and can more effectively reduce the weight of the sliding knife seat 5.
