Description

Height adjustment apparatus
Technical field
[0001] The present application relates to the field of laser tool accessories, in particular to a height adjustment apparatus for a laser tool.
Background art
[0002] In the prior art, a manual height adjustment apparatus is already used as an accessory of a laser tool, to aid measurement. This allows a user to mount the laser tool on the accessory, and adjust the height of the laser tool on a level surface. However, when the laser tool or the accessory is mounted in a high position, or if the laser tool and a working position are separated by a gap, the adjustment of a laser light ray back and forth by means of the manual height adjustment apparatus 100 will not be efficient enough, or a greater amount of manpower assistance will be needed.
Content of the invention
[0003] The main technical problem to be solved by the present application is how to provide an efficient and reliable height adjustment apparatus.
[0004] In order to solve the abovementioned technical problem, the present application provides a height adjustment apparatus, comprising: a mounting support, having a base for mounting a workpiece; a drive part, connected to the mounting support and used for driving the mounting support to move; and a height adjustment guide rail, cooperating with the drive part and providing a movement pathway for the drive part; in a height adjustment state, the drive part being able to drive the mounting support to move along the height adjustment guide rail; in a non-height adjustment state, the drive part remaining locked relative to the height adjustment guide rail.
[0005] According to the technical solution of the present application, the mounting support is driven to move up/down along the height adjustment guide rail by controlling the drive part, thereby realizing adjustment of a working height of the workpiece to be mounted in the vertical direction, and ensuring that it better achieves its own working result.
Description of the accompanying drawings
[0006] By reading the following detailed explanation of particular embodiments with reference to the accompanying drawings, a fuller understanding of the present application will be gained; identical reference labels in the drawings represent identical elements in the drawings. Here:
Fig. 1 shows a schematic diagram of a height adjustment apparatus; and Fig. 2 shows a schematic diagram of a movement direction of a height adjustment apparatus.
Particular embodiments
[0007] Referring to figs. 1 and 2, the height adjustment apparatus 100 comprises a mounting support 110, a drive part 120 and a height adjustment guide rail 130. In a height adjustment state, the drive part 120 can drive the mounting support 110 to move along the height adjustment guide rail 130; in a non-height adjustment state, the drive part 120 remains locked relative to the height adjustment guide rail 130. These components are described in turn below.
[000S] With regard to the mounting support 110, this has a base 111 for mounting a workpiece 200, and guide parts H2a, H2b connected to the base 111. As shown in the figures, the guide part H2a and the base 111 are arranged on the same side of the height adjustment guide rail 130; the guide part 1 l2b is arranged on another side of the height adjustment guide rail 130. At this time, the guide part 1 l2a and the guide part 1 l2b realize a guiding function in relation to the height adjustment guide rail 130. In the height adjustment state, the guide part H2a and the guide part H2b can ensure that the drive part 120 moves up/down along the height adjustment guide rail 130, and will not move in another direction; and in the non-height adjustment state, the guide parts 1 l2a, 1 l2b remain stationary relative to the height adjustment guide rail 130.
[0009] In addition, the height adjustment apparatus 100 further comprises multiple rollers l40a, l40b; the multiple rollers l40a, l40b are disposed between the guide parts H2a, H2b and the height adjustment guide rail 130, and are used to reduce friction between the guide parts 1 l2a, 1 l2b and the height adjustment guide rail 130. Through the provision of the rollers, when the guide parts H2a, 1 l2b and the height adjustment guide rail 130 experience relative movement in the vertical direction, the friction therebetween changes from direct contact sliding friction to rolling friction, enabling the friction therebetween to be greatly reduced, so that there is smoother and steadier relative movement therebetween.
[0010] Still referring to fig. 1, in this embodiment, the rollers l40a, l40b are disposed on the drive part 120 on two sides of the height adjustment guide rail 130 respectively, so that friction of contact faces therebetween can be reduced on both sides, thereby providing steadier relative movement.
[0011] Referring to fig. 2, more specifically, the roller l40a on the guide part H2a on the same side as the base 111 is disposed below the base 111 ; and the roller l40b on the guide part 112b on a different side from the base 111 is disposed above the base 111. At this time, the guide parts 112a, H2b can not only rotate relative to the height adjustment guide rail 130, but also move up/down relative to the height adjustment guide rail 130. For example, in the conventional height adjustment state, the drive part 120 can be directly controlled so as to drive the base 111 to move up/down in a Y direction defined by the guide parts 1 l2a, 1 l2b and the height adjustment guide rail 130. At this time, due to the presence of the rollers l40a, l40b between the guide parts H2a, H2b and the height adjustment guide rail 130, there is rolling friction therebetween, such that the relative movement therebetween has a steadier speed, to facilitate precise adjustment of a target height of the workpiece on the height adjustment apparatus. If there is still a long distance between the workpiece and the target height, it is desired to move the base and the workpiece located thereon at a faster speed. At this time, first of all the guide parts 1 l2a, 1 l2b can be rotated in an X direction, such that there is no longer any contact between the guide parts H2a, H2b and the height adjustment guide rail 130. The drive part 120 is then controlled so as to drive the base 111 to move up/down at a faster speed in the Y direction defined by the height adjustment guide rail 130, so that the workpiece 200 can approach the target height more quickly. A step of precise height adjustment is then performed. This manner of height adjustment simultaneously takes into account both efficiency and accuracy.
[0012] Furthermore, with regard to the drive part 120, this is connected to the mounting support 110, and is used to drive the mounting support 110 to move up/down in a direction defined by the guide parts H2a, 1 l2b in relation to the height adjustment guide rail 130. Height adjustment guide rail 130 cooperates with the drive part 120, and provides a movement pathway for the drive part 120;
in one particular embodiment, the drive part 120 may comprise a worm 121, and the height adjustment guide rail 130 may comprise a rack 131. At this time, the worm 121 cooperates with the rack 131, thereby driving the base 111 and the workpiece 200 on the base 111 to move up/down, and realizes high-precision position adjustment in terms of height.
[0013] Here, a wireless communication module may also be included, performing communication with the height adjustment apparatus 100, the workpiece 200 to be mounted, or both of these simultaneously. An example is a bluetooth module, etc. Remote control of the height adjustment apparatus, and remote control of a function of the mounted workpiece itself, can thereby be realized.
[0014] Optionally, the height adjustment apparatus 100 may further comprise an energy supply module 150 disposed on the base 111, thereby realizing the supply of energy to the drive part. Optionally, in another embodiment, there is no need to provide an independent energy supply module for the height adjustment apparatus; instead, an energy supply module belonging to the workpiece to be mounted itself is used directly to take care of the supply of energy to the height adjustment apparatus as well. This type of energy supply module belonging to a component itself is relatively well-developed prior art, e.g. Chinese patent ZL20162 0824510.5 has already made a disclosure in relation to this; for this reason, no further description of this will be given here.
[0015] In addition, a power transmission line may also be provided on the height adjustment guide rail 130. For example, this is disposed on two sides of the rack 131 on the height adjustment guide rail 130. The power transmission line may be used for transmitting signals between the height adjustment apparatus 100 and the workpiece 200 to be mounted, thereby realizing remote communicative control of the two components, so that the height adjustment apparatus 100 can perform height adjustment in a controlled manner, and the workpiece 200 to be mounted can perform work in a controlled manner; in addition, the power transmission line may also be used as a power supply line, thereby realizing the supply of electrical energy to the height adjustment apparatus 100.
[0016] As one specific application scenario of the embodiments of the height adjustment apparatus 100 described above, it may be used for height adjustment of a laser tool. At this time, the workpiece 200 to be mounted is the laser tool. Through the up/down movement of the drive part in the height adjustment apparatus 100 described above along the height adjustment guide rail 130, the base 111 and the laser tool on the base 111 are driven to perform height adjustment, thereby realizing precise positioning of the laser tool in terms of a vertical coordinate, so that it can realize functions such as laser measurement or laser etching.
[0017] The particular embodiments above are merely intended to explain the present application, without restricting it. In order to explain relative positional relationships, relative directional terms such as left and right, up and down are used in the present application, but these are not definitions of absolute position. Those skilled in the art could still make various changes and modifications to the technical solution of the present application without departing from the scope of the present application, thus all equivalent technical solutions are also included in the category of the present application, and the scope of patent protection of the present application should be defined by the claims.
