New description: [New technical field] This is a cutting device, especially a cutting device suitable for display substrates. ..... [Previous technology] With the advent of the information age, not only desktop computers and notebook computers • # Multimedia products are becoming more and more popular, and the size of various video or video devices is becoming thinner and lighter: traditional Although the cathode ray display still has its advantages, due to the internal electronic robbing structure, its volume is extremely large and heavy, and there are still radiation damage to the user's eyes in use; therefore, In recent years, liquid crystal displays (Liquid Dispw LCDs), which have the advantages of lightness, high brightness, low power consumption and pure shot, have gradually replaced traditional cathode ray displays as mainstream products in the consumer market. The liquid crystal display panel generally needs to be cut and cut to a desired size > size by using a cutting device such as a knife wheel cutting device during the manufacturing process. In the conventional cutting device, if the driving method involving rotation is used, it is necessary to install a bearing 7 pieces. The creator of the present invention found that due to the actual production of the bearing: a roller 93 is interposed between the inner ring 91 and the outer ring 92, and there is a gap t between the roller 93 and the outer portion 92 in the radial direction, as shown in the figure. As shown in Fig. 1, this gap is one of the factors that cause impact noise and vibration during the operation of the second bearing. In the case of the second, the vibration of the cutting lead ('4) will have a large negative impact on the cutting result. Therefore, it is necessary to propose an M413554 improvement scheme for the radial clearance problem of the above bearing, thereby improving the cutting effect and the life of the device. . [New content] The cutting device of the present invention comprises a knife seat, a bearing shaft, a proximal bearing, a distal bearing, an inner spacer, an outer spacer and a pressing member. The bearing shaft is protruded from the seat. a proximal bearing includes a proximal bearing inner ring and a proximal bearing outer ring and is secured to the carrier shaft by a proximal bearing inner ring. The distal bearing includes a distal bearing inner ring and a distal bearing outer ring and is secured to the carrier shaft by a distal bearing inner ring. The proximal bearing (four) end bearing is adjacent to the seat 1 ring axially against the top seat. ^ The above-mentioned pressing member axially abuts the inner end of the distal bearing. In addition, the inner spacer is interposed between the inner ring of the proximal bearing and the inner ring of the distal bearing. The outer spacer is sandwiched between the outer ring of the proximal bearing and the outer ring of the distal bearing, and the outer degree is greater than the inner interval. Sheet thickness. By the above cutting device design, the radial clearance problem between the distal bearing and the proximal bearing is eliminated, and a vibration factor is reduced. Due to the lateral force of the cutter wheel, the 捃 „ 认 人 人 人 八 八 : : : : : : : : : 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 The screw is locked on the bearing shaft. The above-mentioned tool holder can hold the cutter wheel. The cutting device can further comprise at least one spacer sandwiched between the inner rings of the forced end bearing, and the suitable component is transmitted through the spacer shaft:: ring, The urging force of the average pressing member is the inside of the damaging bearing M413554. [Embodiment] Referring to Figures 2 to 4, respectively, the exploded view of the cutting device of the preferred embodiment is a plan view and a cross-sectional view. The utility model mainly comprises a knife seat U, a bearing shaft 12, two bearing 13 M, an inner spacer 15 and an outer spacing; the W6, the pressing member and the second pressing knife hold a cutter wheel 20 at the front end, The workpiece 12 is protruded from the rear end of the holder U, and the end surface of the bearing shaft 2 is axially recessed with a central hole m, and a thread is formed in the hole wall. , U respectively refers to a proximal bearing 13 and a distal bearing 14, both of which are sleeved on the carrier shaft 12, and the proximal end The bearing 13 is relatively close to the seat u. The inner spacer 15 and the outer spacer 16 are sandwiched between the two bearings 1314, and specifically, the inner spacer 15 is sandwiched between the inner end inner ring 131 and Between the distal bearing inner rings 141, the outer spacer 16 is interposed between the proximal bearing outer ring 132 and the distal bearing outer ring 142. Further, the outer spacer 16 has a thickness greater than the inner spacer thickness, as shown in FIG. The thickness difference between the two is... The inner portion of the embodiment 15 is separated from the outer spacer 16 by a separate piece. The piece 17 is strict:; the η, " and the two spacers 15, 16 are positioned after the ' In order to force the back end bearing, the pressing member 17 of the present embodiment uses the _ thread. The column portion 171 of the screw is aligned with the center hole 121 and the head 172 of the 〇Ρ 171 end is pressed. Abutting the inner ring U1 of the distal bearing. - As described above, the locking force is tight. #17' per inner ring 13 of the bearing 13 (14) is relatively moved with the outer ring 1 3 2 (1 42), so that the bearings 1 3 (14) Touch "Change 30%" =; This: Ring 131 ((4) is the inner % - roller - outer ring does contact and eliminates the radial 5 M413554 gap state, as shown in Figure 4. From the above, this is known Invasive By using only two different thicknesses of the spacer Μ π, the conventional radial gap in the bearing is eliminated, the vibration of the bearing operation is effectively reduced, and the lateral force of the cutter wheel is greatly reduced. Therefore, the life of the cutting device The lifting and cutting lines are also more detailed. Between the pressing member 17 and the distal bearing inner ring 141, spacers 18, 19 may be added to average the locking force. The above embodiments are merely examples for convenience of explanation. The scope of the present invention is defined by the scope of the patent application, and is not limited to the above embodiments.
