Description

Technical Field

[0001] The utility model belongs to the technical field of manual multi-axis adjustment platforms, and in particular relates to a manual XYZ axis moving platform. Background Art

[0002] The commonly used manual XYZ platform cannot continuously and accurately position within the travel range when it is displaced, and can only be used in scenes where positioning requirements are not high. Other types of XYZ platform displacement can accurately position, but because the platform displacement distance is large, it cannot quickly position to the required position, which is very inconvenient to operate.

[0003] The commonly used electric-driven multi-axis adjustment table is also unable to quickly achieve precise positioning, and the positioning process is slow and inefficient.

[0004] Therefore, how to provide a manual XYZ axis moving platform is a problem that those skilled in the art need to solve urgently. Utility Model Content

[0005] In view of this, the utility model provides a manual XYZ axis moving platform, which can be quickly roughly positioned and then accurately adjusted, and the adjustment is convenient and efficient.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a manual XYZ axis moving platform, which includes:

[0007] A bottom plate, a Z-axis slide rail is vertically fixed to the middle of one side of the bottom plate, a Z-axis lifting mechanism is slidably connected to the Z-axis slide rail, and a Z-axis fine-tuning slide table is connected to the end of the Z-axis lifting mechanism;

[0008] A Y-axis adjustment base, wherein a transition plate is slidably connected to the top of the Y-axis adjustment base in the Y-axis direction; a Y-axis adjustment component is provided on one side of the Y-axis adjustment base, and the Y-axis adjustment component is used to adjust the movement of the transition plate;

[0009] An X-axis adjustment base, the X-axis adjustment base is fixed to the transition plate and moves synchronously with the transition plate, a table is slidably connected to the top of the X-axis adjustment base corresponding to the X-axis direction, an X-axis adjustment component is provided on one side of the X-axis adjustment base, and the X-axis adjustment component is used to adjust the movement of the table;

[0010] The X-axis adjustment assembly and the Y-axis adjustment assembly both include a mounting frame, an adjustment rod, an adapter, a screw sleeve and a conversion handle. The mounting frame is fixed to one side of the Y-axis adjustment base or the X-axis adjustment base, the adjustment rod is rotatably connected to the mounting frame, the adapter is fixedly connected to the table or transition plate on the corresponding side and moves axially relative to the adjustment rod, a screw sleeve is connected between the adjustment rod and the adapter, the inner side wall of the screw sleeve is gap-matched with the outer side wall of the adjustment rod and the conversion handle on the adapter is used to adjust the screw sleeve and the adjustment rod to a tight relationship.

[0011] The beneficial effects of the utility model are as follows: the rough positioning of the table in the XY directions can be achieved by utilizing the X-axis adjustment component and the Y-axis adjustment component, and the tightness of the screw sleeve and the adjusting light rod can be changed by switching the handle; when the screw sleeve and the adjusting light rod are in a relaxed state, the adapter can slide axially relative to the adjusting light rod, and the screw sleeve does not affect the movement of the adapter; in this state, preliminary rough positioning can be achieved; when the screw sleeve and the adjusting light rod are in a tight state, due to the axial offset of the screw sleeve and the adjusting light rod, an oblique friction force will be generated; under the action of this friction force, when the adjusting light rod is rotated, the screw sleeve and the adapter will move on the adjusting light rod, and a fine-tuning effect can be achieved in this state; the device is easy to use, can achieve rapid adjustment over a large distance, and has high work efficiency.

[0012] Preferably, bearings for mounting the adjusting light rod are connected to both ends of the mounting frame, and a hand wheel is fixedly connected to one end of the adjusting light rod.

[0013] The resulting technical effect is that the adjustment of the light rod is fixed-axis rotation, which can be easily achieved through a hand wheel.

[0014] Preferably, the adapter seat is provided with a avoidance slot for placing the screw sleeve, the screw sleeve is in an odd number, the screw sleeve is connected to the outer wall of the adjusting light rod, the adapter seat is rotatably connected with a conversion handle, the execution end of the conversion handle is connected with a cam, the interior of the adapter seat is slidably connected with a pressure plate for pressing against the screw sleeve, the cam contacts the pressure plate and causes the pressure plate to move closer to one side of the screw sleeve.

[0015] The resulting technical effect is that the screw sleeve is located in the avoidance slot, which can limit the position of the screw sleeve and provide activity space for the screw sleeve. The tightness of the screw sleeve relative to the smooth rod can be adjusted by switching the handle.

[0016] Preferably, the handle end of the conversion handle is located outside the mounting frame, and when the handle end of the conversion handle is in a horizontal state, the screw sleeve and the adjusting light rod are in a relaxed state, and the adapter seat slides axially relative to the adjusting light rod; when the handle end of the conversion handle is in a vertical state, the pressure plate presses against the screw sleeve, and the screw sleeve and the adjusting light rod generate an eccentric angle, and the inner side wall of the screw sleeve is in frictional contact with the outer side wall of the adjusting light rod, and when the adjusting light rod is rotated, the screw sleeve and the adapter seat move axially relative to the adjusting light rod under the action of friction force.

[0017] The resulting technical effect is: when the sleeve and the adjusting rod are in a relaxed state, the position of the table or transition plate can be adjusted over a wide range under the action of external force. When the sleeve and the adjusting rod are pressed tightly against each other, the sleeve is easily deflected from the adjusting rod due to its small axial length. There is an inclined contact portion between the deflected sleeve and the adjusting rod, and this contact portion has a large friction force. When the adjusting rod is rotated, the inclined friction force exerted on the nut will have a forward or backward component, thereby completing the forward and backward movement of the nut and the adapter. An odd number of nuts ensures that the friction forces will not be offset, and there is always a forward or backward friction force.

[0018] Preferably, a Z-axis bracket is connected between the base plate and the Z-axis slide rail, and the Z-axis lifting mechanism includes a slide seat, an adjusting bolt and a support arm. The slide seat is slidably connected to the Z-axis slide rail, and an adjusting bolt is threaded on the slide seat. The end of the adjusting bolt abuts against the slide rail to limit the position, one end of the support arm is fixed to the outer side wall of the slide seat, and the Z-axis fine-tuning slide is fixed to the other end of the support arm.

[0019] The resulting technical effect is: the Z-axis bracket increases the adjustment stroke in the Z-axis direction, first using the Z-axis lifting mechanism for rough positioning, and then using the Z-axis fine-tuning slide for precise adjustment.

[0020] Preferably, a plurality of Y-axis slide rails are provided on the top of the Y-axis adjustment base, and a slider matching the Y-axis slide rails is fixed on the bottom of the transition plate; a plurality of X-axis slide rails are provided on the top of the X-axis adjustment base, and a moving block matching the X-axis slide rails is fixed on the bottom of the table.

[0021] The resulting technical effect is that the sliding of the transition plate and the table plate is achieved by means of the slide rails and the corresponding sliders or moving blocks, and the sliding stability is high.

[0022] Preferably, the Z-axis fine-tuning slide includes a fixed block, a sliding block, a micrometer connecting seat, a micrometer and a top block, the fixed block is fixedly connected to the other end of the support arm, the sliding block is slidably connected to the fixed block, the micrometer connecting seat is fixed to a side wall of the fixed block, the micrometer is connected to the micrometer connecting seat, the top block is fixed to a side wall of the sliding block and is located above the micrometer connecting seat, the top head of the micrometer contacts the top block and causes the sliding block and the fixed block to move relative to each other.

[0023] The resulting technical effect is that when the Z-axis fine-tuning slide is adjusted, the micrometer is used for precise adjustment with high adjustment accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See the attached Figures 1 to 6 According to an embodiment of the utility model, a manual XYZ axis moving platform comprises:

[0033] A bottom plate 1, a Z-axis slide rail 2 is vertically fixed in the middle of one side of the bottom plate 1, a Z-axis lifting mechanism 3 is slidably connected to the Z-axis slide rail 2, and a Z-axis fine-tuning slide table 4 is connected to the end of the Z-axis lifting mechanism 3; the Z-axis lifting mechanism can adjust the lifting position in a wide range, and then accurately adjust it through the Z-axis fine-tuning slide table;

[0034] A Y-axis adjustment base 5, the top of which is slidably connected to a transition plate in the Y-axis direction; a Y-axis adjustment component is provided on one side of the Y-axis adjustment base 5, and the Y-axis adjustment component is used to adjust the movement of the transition plate;

[0035] An X-axis adjustment base 6 is fixed on the transition plate and moves synchronously with the transition plate. A table 10 is slidably connected to the top of the X-axis adjustment base 6 in the X-axis direction. An X-axis adjustment component 7 is provided on one side of the X-axis adjustment base 6. The X-axis adjustment component 7 is used to adjust the movement of the table;

[0036] The X-axis adjustment assembly 7 and the Y-axis adjustment assembly both include a mounting frame 71, an adjustment rod 72, an adapter 73, a screw sleeve 74, and a conversion handle 75. The mounting frame 71 is correspondingly fixed on one side of the Y-axis adjustment base or the X-axis adjustment base. The adjustment rod 72 is connected to the mounting frame 71 by fixed-axis rotation. The adapter 73 is fixedly connected to the table 10 or the transition plate on the corresponding side and moves axially relative to the adjustment rod 72. A screw sleeve 74 is connected between the adjustment rod 72 and the adapter 73. The inner side wall of the screw sleeve 74 is in clearance with the outer side wall of the adjustment rod 72 and the tight relationship between the screw sleeve and the adjustment rod is adjusted by the conversion handle 75 on the adapter. When the screw sleeve and the adjustment rod are in a relaxed state, the table or the transition plate can be directly moved. When the screw sleeve and the adjustment rod are in a tight state, the adapter and the adjustment rod cannot slide relative to each other, and the adapter and the table or the transition plate can only be moved by rotating the adjustment rod.

[0037] In other embodiments, bearings 8 for mounting the adjusting light rod 72 are connected to both ends of the mounting frame 71, so that the adjusting light rod can rotate stably on a fixed axis. A hand wheel 9 is fixedly connected to one end of the adjusting light rod 72, and the rotation of the adjusting light rod can be achieved by the hand wheel.

[0038] In other specific embodiments, the adapter seat 73 is provided with an avoidance slot for placing the screw sleeve 74. There are an odd number of screw sleeves 74. The odd number of screw sleeves can avoid the driving friction generated between the screw sleeve and the adjusting light rod from offsetting each other. The screw sleeve 74 is connected to the outer wall of the adjusting light rod 72. A conversion handle 75 is rotatably connected to the adapter seat 73. The execution end of the conversion handle 75 is connected to a cam. The inside of the adapter seat 73 is slidably connected with a pressure plate for pressing the screw sleeve. The cam contacts the pressure plate and causes the pressure plate to move closer to the side of the screw sleeve 74.

[0039] In other embodiments, the handle end of the conversion handle 75 is located on the outside of the mounting frame 71. When the handle end of the conversion handle 75 is in a horizontal state, the screw sleeve 74 and the adjusting rod 72 are in a relaxed state, and the adapter seat 73 slides axially relative to the adjusting rod 72; when the handle end of the conversion handle 75 is in a vertical state, the pressure plate presses against the screw sleeve. Since the axial dimension of the screw sleeve is small, an eccentric angle is generated between the screw sleeve 74 and the adjusting rod 72. Even if the outer wall of the adjusting rod is smooth, friction will be generated between the screw sleeve and the adjusting rod; the inner wall of the screw sleeve 74 is in frictional contact with the outer wall of the adjusting rod 72. When the adjusting rod is rotated, under the action of friction, the screw sleeve 74 and the adapter seat 73 will move axially relative to the adjusting rod 72.

[0040] In some other embodiments, a Z-axis bracket 11 is connected between the base plate 1 and the Z-axis slide rail 2, and the Z-axis lifting mechanism 3 includes a slide seat 31, an adjusting bolt 32 and a support arm 33. The slide seat 31 is slidably connected to the Z-axis slide rail 2, and the adjusting bolt 32 is threadedly connected to the slide seat 31. The end of the adjusting bolt 32 is abutted against the Z-axis slide rail 2 for limiting position, one end of the support arm 33 is fixed on the outer wall of the slide seat 31, and the Z-axis fine-tuning slide 4 is fixed to the other end of the support arm 33.

[0041] In some other specific embodiments, a plurality of Y-axis slide rails 51 are provided on the top of the Y-axis adjustment base 5, and a slider matching the Y-axis slide rail 51 is fixed on the bottom of the transition plate; a plurality of X-axis slide rails 61 are provided on the top of the X-axis adjustment base 6, and a moving block matching the X-axis slide rail 61 is fixed on the bottom of the table 10, so that the sliding of the transition plate and the table is more stable.

[0042] In some other embodiments, the Z-axis fine-tuning slide 4 includes a fixed block 41, a sliding block 42, a micrometer connecting seat 43, a micrometer 44 and a top block 45. The fixed block 41 is fixedly connected to the other end of the support arm 33, the sliding block 42 is slidably connected to the fixed block 41, the micrometer connecting seat 43 is fixed to a side wall of the fixed block 41, the micrometer 44 is connected to the micrometer connecting seat 43, the top block 45 is fixed to a side wall of the sliding block 42 and is located above the micrometer connecting seat 43, the top head of the micrometer 44 contacts the top block 45 and causes the sliding block 42 and the fixed block 41 to undergo relative displacement, thereby realizing precision adjustment, and the moving position can be more accurately controlled.

[0043] Working principle:

[0044] The function of the conversion handle is to switch the transition plate and the table plate between fast movement and uniform movement. The conversion handle can be switched between 0 degree and 90 degree positions by rotating, thereby switching the two movement states of the transition plate or the table plate.

[0045] Specifically, when the conversion handle is rotated to 0 degrees, the executive end cam inside the handle does not press the screw sleeve, and the screw sleeve and the adjustment rod are in a loose state. At this time, the table can slide quickly under the action of external force. When the conversion handle is rotated to 90 degrees, the executive end cam inside the handle presses against the pressure plate, and the pressure plate presses down and adjusts the screw sleeve and the adjustment rod to a tight fit state (in this state, the screw sleeve and the adjustment rod have an axial deflection angle, which simulates the fit between the lead screw and the threaded sleeve). At this time, it is necessary to rotate the handwheel and drive the adjustment rod to rotate, so that the table can move at a uniform speed, and the moving position can be controlled more accurately.

[0046] The specific principle of adjusting the tight fit movement between the smooth rod and the screw sleeve is based on the effect of friction. The friction force causes the screw sleeve to move forward or backward without rotating. At this time, the screw sleeve will move forward or backward with the adapter, thereby completing the adjustment of the table or transition plate.

[0047] As for the device and the method of use disclosed in the embodiment, since they correspond to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0048] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
