Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of equipment installation, in particular to a cabinet damper fitting hole laser positioning device. BACKGROUND

[0002] In order to meet the requirements of anti-vibration and shock, a vehicle-mounted cabinet needs to be installed with dampers at the bottom and back thereof. The dampers installed at the bottom of the cabinet are named as bottom dampers, and the dampers installed at the back of the cabinet are named as back dampers.

[0003] The cabinet bottom dampers are four, two by two as a pair, and each is installed on a adapter plate, and the adapter plate is connected with the ground of the shelter. The back dampers are two, and are connected with the shelter wall separately. In the process of installing the cabinet, the dampers need to be installed on the vehicle-mounted shelter first, and then the cabinet is connected with the dampers. Therefore, when the cabinet is installed, the mounting holes of the adapter plates of the back dampers and the bottom dampers need to be processed on the ground and the wall of the vehicle-mounted shelter, that is, the fitting holes need to be processed. Since the mounting holes are in two different planes and the distribution range is large, the hole positioning of the conventional plane template cannot be realized, and the three-dimensional template or the real cabinet is usually used for fitting hole positioning.

[0004] When the three-dimensional template is used for fitting hole positioning, the size of the template is large. In order to ensure the positioning accuracy of the fitting holes, the template needs to have good rigidity, and thus the weight of the template is also large. When the template is carried into the shelter, multiple people need to operate and the wall of the shelter is easy to be damaged. In addition, since the three-dimensional template is one-to-one corresponding to the cabinet, the number of templates will increase due to the variety of the cabinets, and a large space needs to be occupied for storage, and the management is not convenient.

[0005] When the real cabinet is used for fitting hole positioning, the volume and weight of the cabinet are also large, and the problem of carrying the three-dimensional template into the cabinet also exists. In addition, since the dampers need to be installed on the shelter first when the cabinet is installed, and the cabinet with the dampers needs to be used for fitting hole positioning, additional processes are increased, that is, the dampers are installed on the cabinet, the cabinet is positioned with the holes, the dampers are removed from the cabinet, the dampers are installed in the shelter, and the cabinet is installed on the dampers. The production efficiency is affected.

[0006] Therefore, it is necessary to design a positioning device which is convenient to operate, has strong applicability and high positioning accuracy to meet the requirements of the cabinet damper fitting hole positioning. SUMMARY

[0007] In view of the above analysis, the present application aims to provide a cabinet damper fitting hole laser positioning device to solve the problems of inconvenient installation of the existing cabinet damper and inaccurate fitting hole positioning.

[0018] Further, the laser positioning mechanism is provided with multiple groups; the multiple groups of laser positioning mechanisms are respectively used for positioning a plurality of back damper mark points on the first contrast plane and can mark a plurality of back damper punching points on the bulkhead of the shelter.

[0019] Further, the laser positioning mechanism comprises: a laser head assembly, a locking screw and a laser head assembly support seat; the locking screw is screwed on the laser head assembly support seat by threads; the laser head assembly is slidingly installed on the laser head assembly support seat and is clamped and fixed by the locking screw.

[0020] Further, the laser head assembly comprises a laser head and a serpentine pipe; the laser head is used for emitting laser; the serpentine pipe is fixed in the clamping groove of the laser head assembly support seat through the locking screw; and the laser head is mounted at the end of the serpentine pipe.

[0021] Further, the serpentine pipe is a bendable metal pipe, which can realize the universal torsion function, and further can make the laser line focal point emitted by the laser head be positioned at any position of the first contrast plane or the cabin wall of the shelter.

[0022] Further, the contact positioning mechanism comprises a contact pin and a contact pin seat; the contact pin can be displaced relative to the contact pin seat.

[0023] Further, the contact pin is screwed on the contact pin seat, and rotating the contact pin can make it be displaced relative to the contact pin seat.

[0055] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0056] Example 1

[0057] One specific embodiment of the present invention provides a cabinet vibration damper with a laser positioning device for mounting holes, such as... Figure 1 As shown, it includes: a reference platform 10, a support platform 20, a laser positioning mechanism 30, and a contact positioning mechanism 40; wherein, the support platform 20, the laser positioning mechanism 30, and the contact positioning mechanism 40 are the main parts of the device; the laser positioning mechanism 30 is mounted on the support platform 20 through a support tube 21, and the reference platform 10 is an independent component.

[0058] In practice, the reference platform 10 is used for the shock absorber mounting holes on the printing cabinet 50; the support platform 20 is used to position the bottom shock absorber mark 10-2-1; the laser positioning mechanism 30 is used to position the back shock absorber mark 10-1-1; and the contact positioning mechanism 40 is used to position the relative distance between the back shock absorber mark 10-1-1 and the bottom shock absorber mark 10-2-1 in the horizontal direction.

[0059] The specific structures of the reference platform 10, the support platform 20, the laser positioning mechanism 30, and the contact positioning mechanism 40 are described below to illustrate the specific implementation of the present invention.

[0060] (I) Comparison Platform 10:

[0061] The reference platform 10 includes two mutually perpendicular surfaces: a first reference plane 10-1 and a second reference plane 10-2. The reference platform 10 is used to simulate the rack mounting position, imprinting the mounting hole positions of the bottom and rear vibration dampers of the rack 50. This allows for the calibration of the positions of the laser head 30-1 on the laser positioning mechanism 30 on the support platform 20 and the stylus 41 on the contact positioning mechanism 40.

[0062] like Figure 8As shown, the control platform 10 is an L-shaped structure with two mutually perpendicular flat plates. The control platform 10 has two mutually perpendicular planes, which are respectively a first control plane 10-1 in the vertical direction and a second control plane 10-2 in the horizontal direction. In the present application, the positions of the shock absorber mounting holes on the cabinet 50 are marked on the control platform 10 by transfer printing.

[0063] As shown, the transfer printing of the shock absorber mounting holes on the control platform 10 is as follows: the cabinet 50 is placed on the control platform 10, the bottom surface of the cabinet 50 is attached to the second control plane 10-2, and the back surface of the cabinet 50 is attached to the first control plane 10-1. Further, a bottom shock mark point 10-2-1 corresponding to the position of the bottom shock mounting hole 50-1 of the bottom of the cabinet 50 is marked on the second control plane 10-2. Further, a back shock mark point 10-1-1 corresponding to the position of the back shock mounting hole 50-2 of the back of the cabinet 50 is marked on the first control plane 10-1. Figure 9 As shown, after the transfer printing is completed, the first control plane 10-1 of the control platform 10 is marked with a plurality of back shock mark points 10-1-1, and the second control plane 10-2 is marked with a plurality of bottom shock mark points 10-2-1.

[0064] Figure 10 As shown, after the transfer printing is completed, the first control plane 10-1 of the control platform 10 is marked with a plurality of back shock mark points 10-1-1, and the second control plane 10-2 is marked with a plurality of bottom shock mark points 10-2-1.

[0065] Further, for different models and sizes of cabinets 50, a plurality of back shock mark points 10-1-1 and bottom shock mark points 10-2-1 are transferred and printed on the control platform 10. The plurality of back shock mark points 10-1-1 and bottom shock mark points 10-2-1 corresponding to the same cabinet 50 form a group. Specifically, the plurality of back shock mark points 10-1-1 and bottom shock mark points 10-2-1 are marked on the control platform 10 using different colored marking pens; or the plurality of back shock mark points 10-1-1 and bottom shock mark points 10-2-1 are marked on the control platform 10 in a staggered manner. By simultaneously marking a plurality of hole marking points on the control platform 10, the present application can achieve that one control platform 10 is suitable for a plurality of different models and sizes of cabinets 50.

[0066] (II) Support platform 20:

[0067] As shown, when the support platform 20 is placed on the second control plane 10-2 of the control platform 10, the bottom shock positioning hole 23-2 on the support platform 20 is aligned with the bottom shock mark point 10-2-1 on the second control plane 10-2. When the bottom shock positioning hole 23-2 is aligned with the bottom shock mark point 10-2-1, the contact positioning mechanism 40 is in contact with the first control plane 10-1. The laser positioning mechanism 30 is used to position the back shock mark point 10-1-1 on the first control plane 10-1. Figure 1 ​​

[0068] As Figure 1 shown, the support platform 20 comprises a support tube 21, a flange plate 22 and a base 23.

[0069] As Figure 3 shown, the base 23 of the support platform 20 is provided with a plurality of bottom positioning holes 23-2, the positioning holes on the base 23 are aligned with the bottom mark points 10-2-1 on the second reference plane 10-2, and the bottom mark points 10-2-1 are positioned through the bottom positioning holes 23-2 on the base 23.

[0070] Further, the support tube 21 is fixedly installed on the support platform 20, and the support tube 21 is perpendicular to the support platform 20, and the laser positioning mechanism 30 is installed on the upper end of the support tube 21; as Figure 1 shown.

[0071] Specifically, the lower end of the support tube 21 is fixedly connected with the base 23 through the flange plate 22, and the support tube 21 is perpendicular to the base 23.

[0072] Specifically, the base 23 is provided with a flange mounting hole 23-3, a screw is installed in the flange mounting hole 23-3, and the flange plate 22 is fixedly installed on the base 23 through the screw. The lower end of the support tube 21 is fixedly connected with the flange plate 22 on the base 23, and the upper end is fixedly connected with the adapter plate 34; the laser positioning mechanism 30 is fixedly installed on the adapter plate 34.

[0073] Further, the base 23 is also provided with a contact positioning mechanism mounting hole 23-1 for installing a screw; the contact positioning mechanism 40 is fixedly installed on the base 23 through the screw. By adjusting the extension of the contact positioning mechanism 40 to contact the first reference plane 10-1, the relative positions of the back mark points 10-1-1 and the bottom mark points 10-2-1 are positioned through the contact positioning mechanism 40.

[0074] Further, when the reference platform 10 contacts the side of the cabinet 50 to be installed, the back mark points 10-1-1 and the bottom mark points 10-2-1 can be marked on the first reference plane 10-1 and the second reference plane 10-2 of the reference platform 10.

[0075] Specifically, the bottom vibration absorber of the cabinet 50 is mounted on the bottom adapter plate in a plane, and has good consistency with the mounting position of the bottom vibration absorber of the same type of cabinet. Thus, the base 23 can be used as a plane template of the bottom vibration absorber, and the bottom vibration absorber positioning hole 23-2 is provided on the base 23, which is aligned with the bottom vibration absorber mark point 10-2-1 on the second reference plane 10-2, so as to position the mounting hole of the bottom vibration absorber; further, the base 23 can be provided with multiple bottom vibration absorber positioning holes 23-2 corresponding to different types of cabinets 50, so as to meet the positioning requirements of the mounting holes of different types of cabinets.

[0076] Further, the contact positioning mechanism 40 is fixedly mounted on the support platform 20 and is arranged parallel to the support platform 20; specifically, two contact positioning mechanisms 40 are fixedly mounted on the base 23 of the support platform 20 and are arranged parallel to the base 23.

[0077] Specifically, the contact positioning mechanism 40 is a telescopic structure for positioning the horizontal distance between the bottom vibration absorber mounting hole and the back vibration absorber mounting hole.

[0078] Further, as shown in Figure 11 , Figure 12 When the contact positioning mechanism 40 contacts the side of the shelter of the cabinet to be assembled, the laser positioning mechanism 30 can position the back vibration absorber punching point 60-1 on the bulkhead 60-2 of the shelter 60, and the bottom vibration absorber positioning hole 23-2 on the support platform 20 is used to position the bottom vibration absorber punching point 60-3 on the shelter bottom plate 60-4.

[0079] (III) Laser positioning mechanism:

[0080] In one specific embodiment of the present application, as shown in Figure 1 The laser positioning mechanism 30 comprises a laser head assembly 31, a locking screw 32 and a laser head assembly support seat 33; the locking screw 32 is screwed on the laser head assembly support seat 33; the laser head assembly 31 is slidingly mounted on the laser head assembly support seat 33 and is fixedly clamped by the locking screw 32.

[0081] Further, as shown in Figure 4 The laser head assembly 31 comprises a laser head 31-1 and a serpentine tube 31-2.

[0082] Specifically, as shown in Figure 4 The laser head 31-1 is used to emit laser; the serpentine tube 31-2 is fixed in the clamping groove 33-2 of the laser head assembly support seat 33 by the locking screw 32; and the laser head 31-1 is mounted at the end of the serpentine tube 31-2.

[0083] Specifically, as shown in Figure 4As shown, the serpentine tube 31-2 is a bendable metal tube, which can realize the function of universal twist, and further can make the laser line focal point 31-3 emitted by the laser head 31-1 positioned at any position of the first contrast plane 10-1 or the bulkhead 60-2 of the shelter 60.

[0084] Further, in order to realize the positioning of the plurality of back reduction punching points 60-1, a back reduction plane template 1 is further provided; as shown in Figure 1 、 Figure 2 .

[0085] A plurality of back reduction positioning holes 1-1 are provided on the back reduction plane template 1; the back reduction positioning holes 1-1 are used to align the back reduction punching points 60-1 positioned by the laser positioning mechanism 30 on the bulkhead 60-2 of the shelter 60; when the back reduction plane template 1 is kept horizontal, the points on the bulkhead 60-2 corresponding to the plurality of back reduction positioning holes 1-1 are the plurality of back reduction punching points 60-1.

[0086] The back vibration damper of the cabinet 50 is mounted on the bulkhead 60-2 of the shelter 60, and the plurality of back reduction mounting holes are in a plane, and the back reduction mounting positions of the same cabinet 50 have good consistency. Thus, after the position of a back reduction mounting hole is determined, the back reduction plane template 1 can be used to position other back reduction mounting holes. Further, since only one hole position cannot determine the direction of the back reduction plane template 1, a level 1-2 is provided on the back reduction plane template 1, and when the positions of the plurality of back reduction mounting holes are positioned, the back reduction plane template 1 is in a horizontal state.

[0087] Alternatively, the laser positioning mechanism 30 is provided in multiple groups; the multiple groups of laser positioning mechanisms 30 are respectively used to position the plurality of back reduction marking points 10-1-1 on the first contrast plane 10-1, and can mark the plurality of back reduction punching points 60-1 on the bulkhead 60-2 of the shelter 60. Specifically, the plurality of laser line focal points 31-3 emitted by the laser heads 31-1 of the multiple groups of laser positioning mechanisms 30 on the bulkhead 60-2 of the shelter 60 are the positions of the plurality of back reduction punching points 60-1.

[0088] Further, as shown in Figure 1 、 Figure 5 , the laser head assembly support seat 33 is fixedly mounted on the adapter plate 34 by welding or screws; the side surface of the laser head assembly support seat 33 is provided with a clamping groove 33-2, and the top is provided with a threaded hole 33-1; the laser head assembly 31 is arranged in the clamping groove 33-2, and the locking screw 33-2 is mounted in the threaded hole 33-1.

[0089] As shown in Figure 1 , the laser head assembly 31 is clamped and fixed in the clamping groove 33-2 of the laser head assembly support seat 33 by the locking screw 32, realizing the fixed connection of the laser head assembly 31 and the laser head assembly support seat 33.

[0090] Specifically, the serpentine pipe 31-2 of the laser head assembly 31 is clamped in the clamping groove 33-2 of the laser head assembly support seat 33, and the locking screw 32 is screwed into the threaded hole 33-1 and pressed on the serpentine pipe 31-2 to fix the serpentine pipe 31-2.

[0091] (IV) Contact positioning mechanism:

[0092] In one specific embodiment of the present application, as shown in Figure 1 , Figure 6 , Figure 7 The contact positioning mechanism 40 comprises a contact pin 41, a locking nut 42 and a contact pin seat 43, and the contact pin 41 is capable of displacement relative to the contact pin seat 43.

[0093] Further, the contact pin 41 is screwed on the contact pin seat 43, and rotation of the contact pin 41 can cause it to displace relative to the contact pin seat 43.

[0094] Further, in order to facilitate rotation of the contact pin 41, a handle 44 is fixedly arranged at the end of the contact pin 41, as shown in Figure 1 , Figure 7 .

[0095] As shown in Figure 6 , the contact pin 41 comprises a round head 41-1, a threaded segment 41-2 and a square head 41-3.

[0096] Specifically, the threaded segment 41-2 of the contact pin 41 is screwed inside the contact pin seat 43, and by rotating the threaded segment 41-2 of the contact pin 41, the round head 41-1 can be caused to approach or move away from the contact pin seat 43.

[0097] Specifically, the locking nut 42 is screwed on the threaded segment 41-2 of the contact pin 41, and when the round head 41-1 of the contact pin 41 is in contact with the first reference plane 10-1, the locking nut 42 is rotated to be in contact with the contact pin seat 43, thereby achieving positioning of the contact pin 41 on the contact pin seat 43.

[0098] Specifically, the square head 41-3 of the contact pin 41 is inserted into the square hole 44-2 of the handle 44, and rotation of the handle 44 can cause the contact pin 41 to rotate.

[0099] Further, the edge of the handle 44 is provided with a plurality of slots 44-1, the slots 44-1 of the handle 44 facilitate manual rotation, and the round head 41-1 of the contact pin 41 facilitates precise contact of the contact pin 41 with the first reference plane 10-1.

[0100] The purpose of the contact positioning mechanism 40 of the application is to measure the distance between the base damper mounting hole and the bulkhead 60-2, and the qualitative measurement can be achieved by adjusting the extension length of the stylus 41. Compared with the ruler measurement positioning (which needs to measure two points), the positioning operation using the stylus 41 is more convenient, and the simultaneous contact of the two groups of styluses 41 with the bulkhead 60-2 can keep the side of the support platform 20 parallel to the bulkhead 60-2, avoiding the precision distortion caused by the skew of the support platform 20, and ensuring the positioning accuracy.

[0101] The detailed use method of the above embodiment is as follows:

[0102] 1) Place the cabinet 50 on the calibration platform 10, and make the bottom damper mounting surface of the cabinet 50 abut against the second calibration plane 10-2 and the back damper mounting surface abut against the first calibration plane 10-1. After the adjustment is completed, mark the bottom damper mounting hole 50-1 on the bottom damper and the back damper mounting hole 50-2 on the back damper as the bottom damper mark point 10-2-1 and the back damper mark point 10-1-1, and then move the cabinet away from the calibration platform after the marking is completed.

[0103] 2) Move the support platform 20 provided with the laser positioning mechanism 30 and the contact positioning mechanism 40 to the calibration platform 10, and make the cabinet bottom damper positioning hole 23-2 on the base 23 align with the bottom damper mark point 10-2-1.

[0108] Compared with the prior art, the technical scheme provided by the embodiment has at least one of the following beneficial effects

[0112] Embodiment 2

[0113] In one specific embodiment of the application, a replacement scheme for the cabinet damper fitting hole laser positioning device in embodiment 1 is provided.

[0114] The difference between the embodiment and embodiment 1 is that a two-stage series rotating pair assembly is used instead of the serpentine pipe 31-2 in embodiment 1, as shown in Figure 13 .

[0115] As shown in Figure 13 , the rotating pair assembly comprises a first rotating pair 70 and a second rotating pair 80, and the rotation axis of the first rotating pair 70 and the rotation axis of the second rotating pair 80 are perpendicular to each other.

[0116] Specifically, the rotation axis of the first rotating pair 70 is arranged perpendicular to the axis of the support pipe 21, and the rotation axis of the second rotating pair 80 is arranged parallel to the axis of the support pipe 21.

[0117] In the embodiment, the first rotating pair 70 is used to adjust the pitch angle of the laser head 31-1, and the second rotating pair 80 is used to adjust the circumferential angle of the laser head 31-1, so that the laser line focal point 31-3 of the laser head 31-1 can be positioned at any position of the first reference plane 10-1 or the bulkhead 60-2 of the shelter 60.

[0118] Specifically, the first rotating pair 70 and the second rotating pair 80 have the same structural composition and are connected in series with each other to adjust the angle of the laser head 31-1.

[0119] As shown in Figure 13 , the first rotating pair 70 comprises a rotor 70-1 of the first rotating pair, a dial 70-2, and a stator 70-3 of the first rotating pair.

[0120] The rotor 70-1 of the first rotating pair is sleeved in a rotating hole of the stator 70-3 of the first rotating pair and can rotate relative to the stator 70-3 of the first rotating pair.

[0121] Specifically, the dial 70-2 is integrated at the end of the stator 70-3 of the first rotating pair to record the rotation angle of the rotor 70-1 of the first rotating pair relative to the stator 70-3 of the first rotating pair.

[0122] In implementation, after the laser head 31-1 is positioned at the position of the reference mark point 10-1-1, the deflection angles of the first rotating pair 70 and the second rotating pair 80 are kept unchanged, and the laser positioning mechanism 30 is transferred into the shelter 60 to position the back-reducing punching point 60-1. For positioning and installation of products in a unified batch, only the calibrated scale value of the last time is recorded, and in subsequent operation, the scales of the first rotating pair 70 and the second rotating pair 80 need to be adjusted to meet the positioning requirements without repeated calibration with the reference platform 10.

[0123] Preferably, the first rotating pair 70 and the second rotating pair 80 are both damping rotating pairs, and damping rubber rings are arranged between the rotating pair stators and the rotating pair rotors of the two rotating pairs to keep the position stability after the relative rotation of the two rotating pairs.

[0124] The two groups of rotating pairs in series are used to quantitatively adjust the position and direction of the laser head 31-1, which can reduce the calibration process of the positioning device and improve the operation efficiency.

The gear 46 is rotatably installed inside the stylus seat 43, and can be driven to rotate by the external adjusting wheel 45.

[0130] In this embodiment, the length of the protruding part of the stylus 41 is adjusted, and then the distance between the support platform 20 and the first reference plane 10-1 is positioned.

Preferably, the adjusting wheel 45 and the gear 46 are fixedly connected through a rotating shaft, and the rotating shaft is rotatably installed on the stylus seat 43.

[0134] Specifically, the side surface of the gear mounting hole is provided with a rotating shaft hole, the rotating shaft is rotatably installed inside the rotating shaft hole, and the two ends of the rotating shaft are fixedly connected with the adjusting wheel 45 and the gear 46 respectively.

[0135] In this embodiment, the displacement of the stylus 41 is realized by the adjusting wheel 45 and the gear rack mechanism, the adjusting mode is simple and reliable, the linear displacement of the stylus 41 can be realized, and the rectangular rod of the stylus 41 can ensure that the stylus 41 is perpendicular to the first reference plane 10-1 or the bulkhead 60-2, thereby ensuring the accuracy of positioning.

[0136] Further, a scale is arranged on the upper surface of the stylus 41, the scale when the stylus 41 contacts the first reference plane 10-1 is recorded by the scale, and even if the stylus 41 is mispositioned in the subsequent positioning process, it can be quickly reset to ensure the accuracy of positioning.
