DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] The pneumatic feeding type glass safety angle processing device for a double-sided edge grinding machine of the present invention is as follows: Figures 1 to 6 As shown, it includes a longitudinal movement component 1, a transverse movement component 2 and a spindle component 3; the longitudinal movement component 1 is provided with a longitudinal movement cylinder 11 and a longitudinal movement table 12, the longitudinal movement cylinder 11 drives the longitudinal movement table 12 to move in the front and rear direction, specifically, the longitudinal movement component 1 is provided with a base 13, the base 13 is used to be fixedly installed on the frame of the double-sided edge grinding machine, the longitudinal movement table 12 is installed on the base 13 through two sets of corresponding linear guide pairs, so that the longitudinal movement table 12 can move linearly in the front and rear direction; the transverse movement component 2 is provided with a transverse movement driving cylinder 21 and a transverse movement seat 22, the transverse movement seat 22 is slidably connected to the longitudinal movement table 12 through the corresponding linear guide pairs, so that the transverse movement seat 22 can move forward and backward with the longitudinal movement table 12, and the transverse movement seat 22 can move linearly in the left and right direction, the transverse movement driving cylinder 21 drives the transverse movement seat 22 to move in the left and right direction, specifically, as Figure 3 As shown, the transverse drive cylinder 21 can be an "adjustable stroke cylinder" of the prior art. The cylinder body of the transverse drive cylinder 21 is installed with a cylinder support plate 26, and the cylinder support plate 26 is installed on the side of the longitudinal movement table 12 through corresponding screws. The end of the piston rod of the transverse drive cylinder 21 is screwed with the transverse movement seat 22, and the end of the piston rod of the transverse drive cylinder 21 is also screwed with a nut that is in contact with the transverse movement seat 22, so that the piston rod of the transverse drive cylinder 21 and the transverse movement seat 22 are relatively fixed; Figure 3 and Figure 6 The spindle assembly 3 is installed on the transverse shift seat 22, specifically, the spindle assembly 3 includes a spindle housing 32, the spindle housing 32 is adapted to pass through the transverse shift seat 22, the spindle housing 32 is relatively fixed to the transverse shift seat 22 by corresponding screws, the spindle assembly 3 is provided with a grinding wheel 33 for chamfering the glass plate 99, the transverse shift assembly 2 is provided with a motor 23, the motor 23 is installed on the transverse shift seat 22, the motor 23 drives the connected grinding wheel 33, specifically, the spindle assembly 3 is provided with a spindle 31, the motor 23 is connected to the upper end of the spindle 31 through a multi-V belt 24, and the lower end of the spindle 31 is coaxially and relatively fixedly installed with the grinding wheel 33.

[0036] like Figure 6 As shown, the spindle housing 32 is rotatably connected to a swing seat 34, and the swing seat 34 can swing around the axis of the grinding wheel 33, as shown in FIG. Figure 6 , Figure 8 and Fig.10 As shown, the front and rear symmetrical center line of the grinding wheel 33 (i.e. Fig.10 The front and rear sides of the dotted line in the figure) are respectively provided with stoppers 35 for contacting the glass plate 99, and the stoppers 35 are preferably arranged symmetrically front and back, and the stoppers 35 are correspondingly arranged on the swing seat 34; Figure 1 As shown, the glass safety corner processing device of the present invention further includes a buffer component 4, such as Figure 6 and Figure 7 As shown, the buffer assembly 4 is provided with a buffer cylinder 42 and a swing rod 44, and the buffer cylinder 42 is provided with a buffer cylinder piston rod 421. Figure 4 and Figure 7 As shown, the front and rear sides of the rocker arm 44 are respectively provided with buffer cylinders 42, the front part of the rocker arm 44 and the rear part of the rocker arm 44 are respectively connected with the end parts of the corresponding buffer cylinder piston rod 421, and the rocker arm 44 is installed on the rocker seat 34. Specifically, the lower end of the rocker arm 44 is formed with an external threaded portion, and the above-mentioned external threaded portion is installed and connected with the upper part of the rocker seat 34.

[0037] The following briefly describes the working process of the glass safety corner processing device of the present invention: Figure 4 As shown, the piston rods 421 of the buffer cylinders on both sides of the swing rod 44 are in an extended state and respectively press against the front and rear parts of the swing rod 44. It is also preferred that the piston rods 421 of the buffer cylinders are in the extended limit position so that the corresponding two stoppers 35 can stop at Fig.10 In the symmetrical position shown; Fig.10As shown, the conveyor belt device of the double edging machine drives the glass plate 99 to move forward. When the glass plate 99 moves forward to a certain position, the reflective photoelectric sensor of the double edging machine is triggered. The control system of the double edging machine (through the corresponding solenoid valve) controls the transverse drive cylinder 21 to push the grinding wheel 33 to the right to the limit position (limited by the limit structure of the transverse drive cylinder 21 of the adjustable stroke cylinder), and then the control system controls the longitudinal cylinder 11 through the proportional valve 5 to drive the grinding wheel 33 to move forward. The speed at which the longitudinal cylinder 11 drives the grinding wheel 33 to move forward is less than the speed at which the glass plate 99 moves forward. Therefore, as shown in FIG. Fig.11 As shown, the front side of the glass plate 99 can move relatively to collide with the stopper 35 located at the rear side of the front and rear symmetrical center line of the grinding wheel 33, and then, as shown in FIG. Fig.12 As shown in the figure, the front corner of the glass plate 99 contacts the grinding wheel 33, so the front corner of the glass plate 99 is processed to form a chamfer 991; in the process from the glass plate 99 contacting the stopper 35 to the front corner of the glass plate 99 being processed to form the chamfer 991, the glass plate 99 pushes the stopper 35 to swing, because the stopper 35 is relatively fixed to the corresponding swing seat 34, and the swing seat 34 can swing around the axis of the corresponding grinding wheel 33, so the swing rod 44 is pushed by the glass plate 99 to overcome the thrust of a buffer cylinder 42, so the swing rod 44 swings with the corresponding swing seat 34; the prior art is that the corner of the glass plate 99 directly collides with the grinding wheel 33, and the feed speed The faster the speed, the easier it is to cause the glass plate 99 to break or the poor processing effect. The present invention sets a stopper 35. During the period from when the glass plate 99 contacts the stopper 35 to when the glass plate 99 contacts the grinding wheel 33, the glass plate 99 will generate a forward thrust on the longitudinal moving table 22 to accelerate the longitudinal moving table 22 forward. Therefore, the forward speed difference of the grinding wheel 33 when contacting the glass plate 99 is reduced, which is equivalent to a reduction in the grinding feed speed. In the process of the grinding wheel 33 grinding the angular position of the glass plate 99, the forward speed difference of the grinding wheel 33 and the glass plate 99 is further reduced. The buffer cylinder 42 buffers the collision between the glass plate 99 and the grinding wheel 3, thereby avoiding a violent collision at the front angular position of the glass plate 99 due to a large speed difference between the grinding wheel 33 and the glass plate 99, thereby avoiding the breakage of the glass plate 99, thereby improving the processing performance of the glass safety angle processing device of the present invention. On the other hand, due to the buffering effect of the buffer cylinder 42, the collision between the glass plate 99 and the stopper 35 is also buffered, thereby preventing the glass plate 99 from being damaged when it collides with the stopper 35. The control system delays the control of the traverse drive cylinder 21, such as Fig.12 and Fig.13 As shown in FIG. 1 , the front corner of the glass plate 99 is processed, and the control system controls the transverse drive cylinder 21 to drive the grinding wheel 33 to reset and move away from the glass plate 99. Since the stopper 35 leaves the glass plate 99, the thrust of the buffer cylinder 42 can reset the swing rod 44, and the control system then controls the longitudinal cylinder 11 to drive the grinding wheel 33 to move backward and reset; Fig.14As shown, the glass plate 99 keeps moving forward. When the reflective photoelectric sensor leaves the glass plate 99, the signal of the reflective photoelectric sensor is transmitted to the control system. The control system controls the transverse drive cylinder 21 to push the grinding wheel 33 to the right to the limit position accordingly, and controls the longitudinal cylinder 11 to drive the grinding wheel 33 to move forward. The control system adjusts the air pressure input to the longitudinal cylinder 11 through the proportional valve 5 so that the grinding wheel 33 can catch up with the glass plate 99. Fig.15 As shown, the stopper 35 on the front side of the front-rear symmetric center line of the grinding wheel 33 contacts the rear side of the glass plate 99. In the same principle, another buffer cylinder 42 plays a buffering role, so that the forward moving speed of the grinding wheel 33 is reduced, so that the speed difference between the grinding wheel 33 and the glass plate 99 is reduced, as shown in FIG. Fig.16 As shown, the rear corner of the glass plate 99 is also processed to form a chamfer 991. The control system controls the lateral drive cylinder 21 to drive the grinding wheel 33 to reset and move away from the glass plate 99. Fig.17 As shown, the control system controls the longitudinal movement cylinder 11 to drive the grinding wheel 33 to move backward and reset.

[0038] Furthermore, if Figure 7 As shown, the buffer assembly 4 is provided with a support 41, as shown in FIG. Figure 6 As shown, the support 41 is installed on the traverse seat 22, as shown in FIG. Figure 7 As shown, the support 41 is threaded with a travel limit rod 43. Figure 4 As shown, the front and rear sides of the swing rod 44 are respectively provided with travel limit rods 43. In other words, the number of the supports 41 can be set to two, and the swing rod 44 can contact the travel limit rod 43. Specifically, when the front corner of the glass plate 99 is processed, the swing rod 44 will contact the end of a travel limit rod 43 located on the rear side of the swing rod 44, and when the rear corner of the glass plate 99 is processed, the swing rod 44 will contact the end of a travel limit rod 43 located on the front side of the swing rod 44. By rotating the travel limit rod 43, the swing stroke of the stopper 35 can be adjusted. When the swing rod 44 contacts the corresponding travel limit rod 43, the travel limit rod 43 blocks the swing rod 44 from swinging further, so that the relative position of the glass plate 99 and the grinding wheel 33 is limited, thereby limiting the size of the chamfer 991. In other words, through the above-mentioned arrangement, the processing accuracy of the chamfer 991 is high and the size of the chamfer 991 is adjustable.

[0039] like Fig.10 As shown, the above description is for a set of glass safety corner processing devices of the present invention arranged on the left side of the glass plate 99. In actual applications, the glass safety corner processing devices of the present invention are symmetrically arranged on both sides of the glass plate 99, so that the corners on the left and right sides of the glass plate 99 can be processed simultaneously.

[0040] Furthermore, if Figure 7As shown, the travel limit rod 43 is correspondingly threaded with a locking nut 45, and the locking nut 45 is closely connected to the corresponding support 41. Therefore, when the travel limit rod 43 is rotated to adjust the travel of the rocker arm 44, the locking nut 45 is rotated to abut against the side of the support 41 and the locking nut 45 is tightened, so that the swing travel range of the rocker arm 44 can be conveniently locked.

[0041] Furthermore, if Figure 5 and Figure 8 As shown, the swing seat 34 includes a swing ring 341, a connecting shell 342 and a support arm 343. The swing ring 341 is sleeved on the main shaft housing 32. The upper end of the connecting shell 342 is installed and connected to the swing ring 341. The support arm 343 is installed at the lower end of the connecting shell 342. Figure 6 As shown, the support arm 343 and the connecting shell 342 are arranged on the outer side of the grinding wheel 33. Figure 6 and Figure 8 As shown, the stopper 35 is arranged on the upper side of the support arm 343, and the connecting shell 342 is formed with a notch 3421 for exposing the grinding wheel 33. Through the above arrangement, since both the stopper 35 and the grinding wheel 33 can contact the glass plate 99, and the stopper 35 is arranged on the upper side of the support arm 343, the contact between the glass plate 99 and the support arm 343 can be avoided. The connecting shell 342 is arranged on the outer side of the grinding wheel 33, so that the swing seat 34 can bypass the grinding wheel 33 and support the stopper 35. By setting the notch 3421, the grinding wheel 33 can contact the glass plate 99. The above structure is reasonably arranged and easy to manufacture and install.

[0042] Furthermore, if Figure 8 As shown, the spindle housing 32 is formed with an annular groove 321 and a limiting shoulder portion 322. The annular groove 321 is arranged below the limiting shoulder portion 322. Figure 5 As shown, a retaining ring 38 is installed in the annular groove 321, and the swing ring 341 is adapted to be arranged between the retaining ring 38 and the limiting shoulder 322, so that the swing ring 341 is relatively positioned with the spindle housing 32 in the axial direction of the grinding wheel 33. During the installation of the swing seat 34, the swing seat 34 can be upwardly sleeved onto the spindle housing 32, and then the retaining ring 38 can be installed. The retaining ring 38 can be divided into two halves. After the two halves of the retaining ring 38 are respectively inserted into the annular groove 321, the retaining ring 38 is fixed to the spindle housing 32 by corresponding screws. The above structure is reasonably arranged and easy to install.

[0043] Furthermore, if Figure 5 As shown, a gasket ring 37 is provided between the swing ring 341 and the spindle housing 32. The gasket ring 37 can be made of wear-resistant materials in the prior art, such as nylon or tin bronze. The gasket ring 37 acts as a sliding bearing, so that the swing ring 341 can swing flexibly and avoid wear.

[0044] Furthermore, if Figure 8As shown, the gasket 37 is formed with a disconnection seam 371. Since the swing speed of the swing ring 341 is slow and the precision requirement is low, the disconnection seam 371 is provided so that the gasket 37 can be opened when the gasket 37 is put on the spindle housing 32, thereby reducing the precision requirement of the gasket 37 and facilitating installation.

[0045] Furthermore, if Fig. 9 As shown, the support arm 343 is provided with a core shaft 351, and the stopper 35 is cylindrical. The stopper 35 is sleeved outside the corresponding core shaft 351, and the stopper 35 can rotate around the axis of the corresponding core shaft 351, as shown in FIG. Fig.11 As shown, after the stopper 35 contacts the glass plate 99, since the glass plate 99 moves forward in a straight line and the stopper 35 swings around the axis of the grinding wheel 33, the stopper 35 moves in the left and right direction relative to the glass plate 99. By setting the stopper 35 to be able to rotate around the axis of the corresponding core shaft 351, the stopper 35 and the side of the glass plate 99 are in rolling friction, so that the stopper 35 can swing flexibly to avoid affecting the angular position of the grinding wheel 33 when grinding the glass plate 99.

[0046] Further, as described above, since the spindle housing 32 passes through the traverse seat 22, Figure 5 and Figure 6 As shown, the rocker arm 44 is arranged through the transverse seat 22, and the upper part of the rocker arm 44 is located above the transverse seat 22, so that the buffer cylinder piston rod 421 and the stroke limit rod 43 can be arranged on the upper side of the transverse seat 22, which can facilitate the operator to observe and operate during debugging.

[0047] Furthermore, if Figure 6 As shown, the longitudinal cylinder 11 is configured as a rodless cylinder, which is a prior art. Specifically, the front and rear ends of the cylinder body of the longitudinal cylinder 11 are mounted on the base 13 through ears, and the slider of the longitudinal cylinder 11 is sleeved outside the cylinder body of the longitudinal cylinder 11. The slider of the longitudinal cylinder 11 is coupled with the piston of the longitudinal cylinder 11, and the slider of the longitudinal cylinder 11 is connected to the bottom of the longitudinal table 12. The longitudinal cylinder 11 is arranged in the middle of the two corresponding sets of linear guide rails. Since the rodless cylinder outputs the slider at the corresponding part of the piston, it can save layout space when the cylinder stroke is large. Figure 6 As shown, the longitudinal moving assembly 1 is provided with two proximity switches 14 arranged in the front-to-back direction, and the transverse moving assembly 2 is provided with a sensor 25, which can be installed on the lower side of the cylinder body of the transverse moving driving cylinder 21, as shown in FIG. Figure 3 As shown, in the process that the longitudinal cylinder 11 drives the longitudinal platen 12 to move forward and backward, the sensor 25 can trigger the corresponding proximity switch 14. The proximity switch 14 is electrically connected to the control system of the double-sided edge grinding machine. The proximity switch 14 serves as a stroke limiter for the longitudinal cylinder 11, thereby preventing the piston of the longitudinal cylinder 11, which is a rodless cylinder, from frequently colliding with the inner end of the longitudinal cylinder 11 and being easily damaged.

[0048] In summary, the glass safety corner processing device of the present invention has high processing performance and good processing effect.
