Description

Technical Field

[0001] The utility model belongs to the technical field of special vehicle auxiliary equipment, and particularly relates to an end face laser indicator. Background Technique

[0002] When installing the driving wheel of a certain special vehicle, due to the relatively high requirement for installation accuracy, it is necessary to accurately position the installation position of the driving wheel.

[0003] Currently, the method adopted is to install a tooling rod A on the side of the driving wheel and a tooling rod B on the side of the driven wheel. The tooling rod A and the tooling rod B are located on the same side of the vehicle and are separated by a certain distance from each other. A thin wire is used to cross the fixed notches of the two tooling rods, and gravity plumb bobs are hung at both ends of the thin wire. The driving wheel is installed with this thin wire as the reference.

[0004] However, the process of building the reference in this installation method is relatively cumbersome, involving three basic tools: tooling rod A, tooling rod B, and a thin wire with a gravity plumb bob. The installation is rather troublesome, resulting in a relatively low overall efficiency. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an end face laser indicator for solving the problem of the cumbersome construction of the corresponding reference surface during the installation of the driving wheel in the past.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: An end face laser indicator, which includes:

[0007] A positioning connector, the positioning connector having an installation positioning surface for fixed connection;

[0008] A connecting rod, one end of the connecting rod being connected to the positioning connector;

[0009] A laser emitter, installed at the other end of the connecting rod, the laser emitter being used to emit a laser surface parallel to the installation positioning surface as a reference surface.

[0010] Compared with the prior art, the above technical solution has the following beneficial effects:

[0011] The connecting rod and the laser emitter are fixed at the target position through the positioning connector. By closely attaching the installation positioning surface on the positioning connector to the target position, the laser surface emitted by the laser emitter is parallel to the installation positioning surface, quickly and accurately forming a reference surface to replace the original reference surface realized by the cooperation of the thin wire, plumb bob and tooling rod. The installation is simple, and at the same time, the operation steps are simplified, improving the efficiency.

[0012] On the basis of the above technical solution, the embodiment of the present application can also be improved as follows:

[0013] In one embodiment, the positioning connecting member includes at least one connecting rod, one end of the connecting rod is provided with an auxiliary block, and a long circular hole is formed at the other end of the connecting rod along the length direction of the connecting rod.

[0014] The beneficial effect of this step is that by hanging the auxiliary block at one end on a specific position and locking the long circular hole at the other end with fasteners such as bolts, the positioning connecting member can be quickly fixed at the target position. At the same time, the long circular hole can be applicable to installation dimensions of different diameter specifications, improving the adaptability.

[0018] A locking member, which is sleeved on the telescopic seat and is used for tightening and fixing the telescopic seat and the telescopic rod.

[0019] The beneficial effect of this step is that setting the connecting rod as a telescopic connecting rod enables the distance between the laser surface and the installation positioning surface to be adjustable, playing a role in adjusting the position of the laser surface to meet different installation requirements. At the same time, it can also adapt to the installation requirements of driving wheels of different size specifications.

[0020] In one embodiment, the telescopic connecting rod further includes an adjusting unit for adjusting the telescopic amount of the telescopic rod, and the adjusting unit includes:

[0021] An adjusting seat, which is fixed on the telescopic seat, and an adjusting window is formed through between the adjusting seat and the telescopic seat;

[0022] An adjusting cylinder, which is rotatably connected in the adjusting seat, the outer peripheral surface of the adjusting cylinder abuts against the surface of the telescopic rod through the adjusting window, and an adjusting hole is arranged at the axis of the adjusting cylinder.

[0023] The beneficial effect of this step is that by rotating the adjusting cylinder, the friction generated by the contact between the surface of the adjusting cylinder and the surface of the telescopic rod drives the telescopic rod to expand and contract, and the telescopic amount of the telescopic rod can be adjusted more precisely.

[0024] In one embodiment, the telescopic connecting rod further includes a friction strip, the friction strip is embedded on the telescopic rod along the length direction of the telescopic rod, and the outer peripheral surface of the adjusting cylinder abuts against the surface of the friction strip through the adjusting window.

[0025] The beneficial effect of this step is that by adding friction strips, direct contact between the adjusting cylinder and the surface of the telescopic rod is avoided, wear on the telescopic rod is reduced, and the telescopic accuracy is prevented from being affected. The friction strips are convenient to replace and can be directly replaced when worn out excessively.

[0026] In one embodiment, scale lines are arranged on the telescopic rod along its length direction, and a reading window is provided on the telescopic seat corresponding to the scale lines.

[0027] The beneficial effect of this step is that the specific value of the scale line on the telescopic rod can be accurately read through the reading window, and thus the telescopic amount of the telescopic rod can be quickly and accurately seen.

[0028] In one embodiment, the other end of the connecting rod is rotatably connected to a mounting plate about its axial direction, and the laser emitter is fixed on the mounting plate.

[0029] The beneficial effect of this step is that by rotating and connecting the mounting plate at the end of the connecting rod, the laser emitter can be driven to rotate about the axial direction of the connecting rod, so that the pitching angle of the laser plane can be adjusted. At the same time, the orientation of the emitting end of the laser emitter can be adjusted omnidirectionally by 360°, improving the flexibility of the emitting direction of the laser plane.

[0030] In one embodiment, a protective cover is arranged on the mounting plate, the protective cover covers the outside of the laser emitter, and a transmitting notch is provided on the laser protective cover corresponding to the emitting end of the laser emitter.

[0031] The beneficial effect of this step is that the protective cover can, on the one hand, protect the laser emitter, and on the other hand, avoid light pollution and only allow the laser to pass through the transmitting notch.

[0032] In one embodiment, an azimuth adjusting device is further included, and the azimuth adjusting device includes:

[0033] A positioning member fixed on the mounting plate, the emitting end of the laser emitter is axially connected to the positioning member, and the axis of the axial connection of the emitting end is orthogonal to the axis of the connecting rod;

[0034] An adjusting rod, the adjusting rod is screwed to the protective cover, and the end of the adjusting rod abuts against the tail end of the laser emitter. A reset member is connected between the end of the adjusting rod and the mounting plate.

[0035] The beneficial effect of this step is that the emitting end of the laser emitter is fixed by the positioning member, the emitting end is axially connected through the positioning member, and the adjusting rod pushes the tail end of the laser emitter to rotate around the axial connection position of the emitting end to adjust the included angle between the laser plane emitted by the laser emitter and the installation and positioning surface.

[0036] In one embodiment, a support block is further included, which is fixed on the circumferential surface of the connecting rod near one end of the laser emitter.

[0037] The beneficial effect of this step is that by arranging support blocks on the circumferential surface of the connecting rod, when the entire laser pointer is placed, it contacts the ground through the support blocks to prevent the laser emitter from contacting the ground and generating friction.

[0038] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0039] 1. The laser plane emitted by the laser emitter can be accurately and quickly realized, replacing the conventional plumb line to form a reference plane.

[0057] Embodiment

[0058] As Figures 1-4 shown, an end face laser indicator provided by the present utility model is used to replace the reference plane originally formed by the cooperation of two tooling rods, a thin wire and a plumb bob. This application can be quickly installed, so that the reference plane formed by the laser surface 5 can be quickly formed, improving the efficiency and avoiding the reference plane formed by the thin wire in the past.

[0059] The end face laser indicator includes: a positioning connector 1, a connecting rod 2 and a laser emitter 3.

[0060] The positioning connector 1 has a mounting and positioning surface 4 for fixed connection. One end of the connecting rod 2 is connected to the positioning connector 1. The connecting rod 2 is connected to the side of the positioning connector 1 away from the mounting and positioning surface 4. Wherein the connecting rod 2 is perpendicular to the mounting and positioning surface 4. The laser emitter 3 is installed at the other end of the connecting rod 2. The laser emitter 3 is used to emit a laser plane 5 parallel to the mounting and positioning surface 4 as a reference plane. Thus, after positioning and installing on the mounting and positioning surface 4, the laser plane 5 can be quickly positioned.

[0061] The connecting rod 2 and the laser emitter 3 are fixed at the target position through the positioning connector 1. By closely attaching the mounting and positioning surface 4 on the positioning connector 1 to the target position, then the laser plane 5 emitted by the laser emitter 3 is parallel to the mounting and positioning surface 4, quickly and accurately forming a reference plane, which is used to replace the original reference plane realized by the cooperation of a thin line, a plumb bob and a tooling rod. The installation is simple, and at the same time, the operation steps are simplified and the efficiency is improved.

[0062] In this embodiment, the positioning connector 1 includes at least one connecting rod 101. A mounting and positioning surface 4 is formed by cutting one side surface of the connecting rod 101. To ensure the stability of the connection of the connector, an auxiliary block 102 is provided at one end of the connecting rod 101. The auxiliary block 102 is used to be clamped at the target position to play a role in positioning one end of the connecting rod 101. A long circular hole 103 is opened at the other end of the connecting rod 101 along the length direction of the connecting rod 101, and the other end of the connecting rod 101 is fixed by using the long circular hole 103.

[0063] By hanging the auxiliary block 102 at one end at a specific position and locking the long circular hole 103 at the other end with fasteners such as bolts, the positioning connector 1 can be quickly fixed at the target position. At the same time, the long circular hole 103 can be applicable to installation sizes of different diameter specifications, improving the adaptability.

[0064] To improve the adaptability and the diversification and flexibility of adjustment, the connecting rod 2 is set as a telescopic connecting rod 2. Specifically, the telescopic connecting rod 2 includes: a telescopic seat 201, a telescopic rod 202 and a locking member 203.

[0065] The telescopic seat 201 is arranged on the positioning connector 1. The telescopic seat 201 is fixedly connected to the positioning connector 1 through fasteners such as bolts to ensure the stability of the connection. The inside of the telescopic seat 201 is hollow. One end of the telescopic rod 202 is fitted and sleeved in the telescopic seat 201 and can slide back and forth along the length direction of the telescopic rod 202 to change the telescopic amount of the telescopic rod 202 to realize the adjustment of the overall length of the connecting rod 2. The other end of the telescopic rod 202 is connected to the laser emitter 3.

[0066] Specifically, the cross section of the telescopic seat 201 and the telescopic rod 202 that are fitted and sleeved is polygonal to ensure that the telescopic rod 202 will not rotate circumferentially during the telescopic process.

[0067] The locking member 203 is sleeved on the telescopic base 201 and is used to tighten and fix the telescopic base 201 and the telescopic rod 202. Specifically, a plurality of notches are circumferentially spaced at the position of the telescopic base 201 where the locking member 203 is located, so that when the locking member 203 is tightened, the caliber of the telescopic base 201 at this place can be changed, and then the inner telescopic rod 202 can be tightened, increasing the friction between the telescopic base 201 and the telescopic rod 202 to play a fixing role. Among them, the locking member 203 can adopt a clamping hoop or a band clamp, etc.; the notches are opened at the end of the telescopic base 201 away from one end of the positioning connecting member 1, and it is convenient to open the notches at the end.

[0068] The connecting rod 2 is set as a telescopic connecting rod 2, so that the distance between the laser surface 5 and the installation positioning surface 4 is adjustable, which plays a role in adjusting the position of the laser surface 5 to meet different installation requirements, and at the same time can also adapt to the installation requirements of driving wheels of different sizes and specifications.

[0069] As Figure 4 shown, to improve the flexibility and convenience of adjusting the telescopic rod 202, the telescopic connecting rod 2 further includes an adjusting unit 204 for adjusting the telescopic amount of the telescopic rod 202.

[0070] Among them, the adjusting unit 204 includes: an adjusting seat 2041 and an adjusting cylinder 2042.

[0071] The adjusting seat 2041 is fixed on the telescopic base 201. An adjusting window 2043 is formed through between the adjusting seat 2041 and the telescopic base 201. The adjusting window 2043 is located on the surface where the telescopic base 201 and the adjusting seat 2041 are in contact, and penetrates through the telescopic base 201 and the adjusting seat 2041.

[0072] The adjusting cylinder 2042 is rotatably connected in the adjusting seat 2041. The axial direction of the adjusting cylinder 2042 is orthogonal to the axial direction of the connecting rod 2. At this time, the outer peripheral surface of the adjusting cylinder 2042 abuts against the surface of the telescopic rod 202 through the adjusting window 2043, that is, when the adjusting cylinder 2042 rotates in the adjusting seat 2041, the rotating outer peripheral surface of the adjusting cylinder 2042 contacts the surface of the telescopic rod 202, and drives the telescopic rod 202 to move along its axial direction through the friction between them. An adjusting hole 2044 is provided at the axis of the adjusting cylinder 2042, and the adjusting hole 2044 can be set as a polygonal hole such as an internal hexagonal hole, which is convenient for inserting a tool to rotate the adjusting cylinder 2042.

[0073] By rotating the adjusting cylinder 2042, the friction generated by the contact between the surface of the adjusting cylinder 2042 and the surface of the telescopic rod 202 is used to drive the telescopic rod 202 to expand and contract, which can more accurately adjust the telescopic amount of the telescopic rod 202 and avoid the problem that it is not easy to accurately adjust the telescopic amount by pulling the telescopic rod 202.

[0074] To improve the telescoping efficiency of the telescopic rod 202 and avoid wearing it out, the telescopic link 2 further includes a friction strip 2045. The friction strip 2045 is embedded in the telescopic rod 202 along the length direction of the telescopic rod 202, and the setting direction of the friction strip 2045 passes through the adjustment window 2043 along the length direction of the telescopic rod 202. The outer peripheral surface of the adjustment cylinder 2042 abuts against the surface of the friction strip 2045 through the adjustment window 2043. Specifically, a strip-shaped groove is provided at the corresponding position on the telescopic rod 202, and the friction strip 2045 is fastened in this strip-shaped groove by means of bolts or the like.

[0075] Since part of the friction strip 2045 protrudes from the surface of the telescopic rod 202, it is easier for the surface of the adjustment cylinder 2042 to contact the surface of the friction strip 2045; by adding the friction strip 2045, the direct contact between the adjustment cylinder 2042 and the surface of the telescopic rod 202 is avoided, reducing the wear on the telescopic rod 202 and preventing the influence on the telescopic accuracy. The friction strip 2045 is convenient to replace and can be directly replaced after excessive wear.

[0076] To facilitate the quick reading of the telescopic amount of the telescopic rod 202, scale lines 205 are provided on the telescopic rod 202 along its length direction, with the telescopic amount numbers specifically marked. A reading window 206 is provided on the telescopic base 201 corresponding to the scale lines 205. The scale lines 205 on the telescopic rod 202 can be seen through the reading window 206, and an indicating scale line is provided at the reading window 206.

[0077] Through the reading window, the specific value of the scale line 205 on the telescopic rod 202 can be accurately read, and then the telescopic amount of the telescopic rod 202 can be quickly and accurately seen.

[0078] Such as Figure 2 、 3 As shown, to facilitate the rotational adjustment of the laser emitter 3 around the axis of the telescopic rod 202, a mounting plate 6 is rotatably connected to the other end of the link 2 around its axis, and the laser emitter 3 is fixed to the mounting plate 6.

[0079] By rotating and connecting the mounting plate 6 at the end of the link 2, the laser emitter 3 can be driven to rotate around the axis of the link 2, enabling the pitching angle of the laser plane 5 to be adjustable. At the same time, the orientation of the emitting end of the laser emitter 3 can be adjusted omnidirectionally by 360°, improving the flexibility of the emitting direction of the laser plane 5.

[0080] Specifically, as Figure 3As shown in the figure, a semi-circular guide groove 601 is formed on the mounting plate 6, and a limit protrusion extending into the guide groove 601 is provided at the end of the telescopic rod 202, which is used to limit the rotation angle of the mounting plate 6. At the two extreme end positions of the guide groove 601, the emission direction of the laser emitter 3 is controlled to be perpendicular to the length direction of the positioning connecting rod 101. That is, when the positioning connecting rod 101 is vertically arranged, when the guide groove 601 is at the two extreme end positions, the emission direction of the laser emitter 3 is the horizontal direction, so as to ensure that the laser emitter 3 can control the laser emission direction in the forward or backward horizontal direction, and at the same time meet the irradiation in the forward and backward directions. Coupled with the fact that the laser surface 5 emitted by the laser emitter 3 is a fan-shaped laser surface 5, the coverage area is relatively wide.

[0081] A protective cover 7 is provided on the mounting plate 6. The protective cover 7 covers the outside of the laser emitter 3, and the laser emitter 3 is fixedly covered therein through the cooperation of the protective cover 7 and the mounting plate 6. A emission notch 8 is opened on the protective cover 7 corresponding to the emission end of the laser emitter 3. The length direction of the emission notch 8 is vertically arranged and coincides with the fan-shaped laser surface 5 emitted by the laser emitter 3.

[0082] On the one hand, the protective cover 7 can play a role in protecting the laser emitter 3, and on the other hand, it can also avoid light pollution and only allow the laser to pass through the emission notch 8.

[0083] As Figure 3 shown in the figure, in order to improve the adjustment flexibility of the laser surface 5, an azimuth adjustment device 9 is further included. The azimuth adjustment device 9 includes: a positioning member 901 and an adjustment rod 903.

[0084] The positioning member 901 is fixed on the mounting plate 6. The positioning member 901 is a clamp member fixedly installed on the mounting plate 6, and a fixed frame fixed on the outer periphery of the laser emitter 3 is formed between the positioning member 901 and the mounting plate 6. The emission end of the laser emitter 3 is axially connected to the positioning member 901. Specifically, by drilling a hole 902 in the positioning member 901 and screwing in an internal screw to rotatably connect with the outside of the emission end of the laser emitter 3, at this time, the laser emitter 3 rotates around this axis. The axis line of the axial connection of the emission end is orthogonal to the axis line of the connecting rod 2, so as to realize the left and right rotation of the laser emitter 3 around this axis. When rotating, it rotates left and right around the intersection point of the axis line of the telescopic rod 202 and the laser emission end to change the azimuth angle of the laser emission surface.

[0085] The adjusting rod 903 is screwed to the protective cover 7, and the end of the adjusting rod 903 abuts against the tail end of the laser emitter 3. By rotating the adjusting rod 903, the tail end of the laser emitter 3 can be driven to rotate left and right around its emitting end. A reset member 904 is connected between the end of the adjusting rod 903 and the mounting plate 6. The reset member 904 can be realized by a reset spring. When the adjusting rod 903 is screwed out, the reset spring can push the laser emitter 3 outward. When the adjusting rod 903 is screwed in, the end of the adjusting rod 903 pushes the laser emitter 3 to move inward.

[0086] The emitting end of the laser emitter 3 is fixed by the positioning member 901, and the emitting end is pivotally connected through the positioning member 901. The adjusting rod 903 pushes the tail end of the laser emitter 3 to rotate around the pivot point of the emitting end, so as to adjust the angle between the laser plane 5 emitted by the laser emitter 3 and the mounting and positioning plane 4.

[0087] To prevent the laser emitter 3 from contacting and rubbing against external objects when placed, a support block 10 is further included. The support block 10 is fixed to the circumferential surface of the connecting rod 2 near one end close to the laser emitter 3. By arranging the support block 10 on the circumferential surface of the connecting rod 2, when the entire laser indicator is placed, the support block 10 contacts the ground, so as to prevent the laser emitter 3 from contacting the ground and generating friction.

[0088] During specific use, the positioning connecting rod 101 is fixed to the mounting surface through the auxiliary block 102 and the long circular hole 103. At this time, the mounting and positioning plane 4 fits the mounting surface. The laser emitter 3 at the other end of the connecting rod 2 directly emits a laser plane 5 in the vertical plane direction to replace the reference plane of the plumb line formed by the original thin line. Since the connecting rod 2 can be telescopically adjusted and the connecting rod 2 is perpendicular to the mounting and positioning plane 4, the elongation of the connecting rod 2 can drive the laser emitter 3 to translate outward, realizing the left and right translation adjustment along the axis of the connecting rod 2, and then driving the laser plane 5 to move left and right on this horizontal plane to adapt to different specifications of wheels. At the same time, the left and right rotation adjustment of the laser emitter 3 can be realized through the azimuth adjustment device 9. On this horizontal plane, the laser emitter 3 rotates left and right around the intersection point of the axis of the connecting rod 2 and the emitting end, changing the adjustment of the laser plane 5 and the mounting and positioning plane 4, improving the adjustment dimension of the laser plane 5. When the mounting and positioning plane 4 does not fit the mounting surface, by adjusting the azimuth adjustment device 9 to change the left and right rotation angle of the laser, the laser plane 5 is adjusted to a suitable target position.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
