Description

Technical Field

[0001] This utility model relates to the technical field of marble triaxial base, and in particular to a track-limited marble triaxial base. Background Technology

[0002] The marble triaxial base is a high-precision, high-stability platform, mainly used in precision machining and testing.

[0003] Existing marble triaxial bases are heavy, making them difficult to move or adjust, thus limiting the mobility of the device and reducing its flexibility. To address this, we provide a track-limited marble triaxial base. Utility Model Content

[0004] To address the issue of reduced device flexibility caused by the inconvenience of moving or adjusting the position of the marble triaxial base in the aforementioned background technology, this utility model provides a track-limited marble triaxial base.

[0005] This utility model is achieved by the following technical solution: a track-limited marble three-axis base, including a marble base, an adjustment and movement component and a movement protection component, wherein a support base is fixedly connected to the bottom of the marble base.

[0006] The adjusting and moving assembly includes two sets of bidirectional lead screws rotatably connected to the support base. Threaded blocks are threaded to the outer sides of both sides of the bidirectional lead screws. The support legs of the support base are provided with storage grooves. Sliding blocks are slidably connected inside the storage grooves. Universal wheels are movably connected to the bottom of the sliding blocks. A connecting beam is fixedly connected between the two sets of sliding blocks on the same side. A connecting rod is hinged between the connecting beam and the two sets of threaded blocks on the same side through a hinge.

[0007] The movable protection assembly includes four sets of vertical rods symmetrically and movably connected to the support base. A fixing plate is fixedly connected to the top of the vertical rod, and a protective component is fixedly connected to the top of the fixing plate. A horizontal rod is fixedly connected to the threaded block, and a connecting rod two is hinged between the horizontal rod and the vertical rod on the same side through a hinge.

[0008] As a further improvement to the above scheme, one end of each of the two sets of bidirectional lead screws is coaxially fixedly connected to a sprocket, and the two sets of sprockets are connected by chain drive. A handwheel is coaxially fixedly connected to one side of the sprocket.

[0009] As a further improvement to the above solution, four sets of guide brackets are symmetrically fixedly connected to the support base, and the guide brackets are slidably connected to the vertical rod on the same side.

[0010] As a further improvement to the above solution, the protective component is made of rubber.

[0011] As a further improvement to the above solution, the protective component is designed with an L-shaped structure.

[0012] As a further improvement to the above solution, a slide rail is provided on the top side of the marble base, and a sliding connecting seat is slidably connected to the outside of the slide rail.

[0013] As a further improvement to the above solution, the slide rail is fixedly connected to the marble base by fixing bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by rotating the handwheel and through the transmission between the sprocket and the chain, enables two sets of bidirectional lead screws to rotate simultaneously in the same direction. The rotation of the bidirectional lead screws can also drive two sets of threaded blocks connected to them to move in opposite directions. Utilizing the sliding engagement between the storage groove and the sliding block, and the hinged engagement between the connecting beam and the threaded block and the connecting rod, the universal wheel at the bottom of the sliding block can be pushed vertically downward until it moves out of the storage groove. At this time, the universal wheel will contact the ground to facilitate the movement of the marble three-axis base, making it highly practical.

[0016] 2. In the process of pushing the universal wheel out of the storage slot, the movement of the threaded block can also drive the horizontal bar to move together. With the sliding cooperation between the vertical bar and the guide bracket, and the hinged cooperation between the vertical bar, the horizontal bar and the connecting rod 2, the protective part on the fixed plate can be pushed vertically upward at the same time. This can protect the corners of the marble triaxial base and prevent them from being damaged by collision during movement, thus further improving the practicality of the device.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example 1:

[0025] Please combine Figure 1-4 This embodiment of a rail-limited marble three-axis base includes a marble base 1, a support seat 2 fixedly connected to the bottom of the marble base 1, a slide rail 3 provided on one side of the top of the marble base 1, and a sliding connecting seat 4 slidably connected to the outside of the slide rail 3. The sliding connecting seat 4 facilitates the installation of testing and processing equipment. The slide rail 3 is fixedly connected to the marble base 1 by fixing bolts, which facilitates the disassembly and assembly of the slide rail 3.

[0026] An adjusting and moving assembly for moving a marble three-axis base includes two sets of bidirectional lead screws 101 rotatably connected to a support base 2. Threaded blocks 102 are threadedly connected to the outer sides of both sides of the bidirectional lead screws 101. A storage groove 103 is provided on the support leg of the support base 2. A sliding block 104 is slidably connected inside the storage groove 103. A universal wheel 105 is movably connected to the bottom of the sliding block 104. A connecting beam 106 is fixedly connected between the two sets of sliding blocks 104 on the same side. A connecting rod 107 is hinged between the connecting beam 106 and the two sets of threaded blocks 102 on the same side. A sprocket is coaxially fixedly connected to one end of each set of bidirectional lead screws 101. The two sets of sprockets are connected by a chain 108. A handwheel is coaxially fixedly connected to one sprocket.

[0027] A movable protective assembly for protecting the corners of a marble triaxial base includes four sets of vertical rods 201 symmetrically and movably connected to a support base 2. A fixing plate 202 is fixedly connected to the top of each vertical rod 201, and a protective element 203 is fixedly connected to the top of the fixing plate 202. A horizontal rod 204 is fixedly connected to a threaded block 102. A connecting rod 205 is hinged between the horizontal rod 204 and the vertical rod 201 on the same side. Four sets of guide brackets are symmetrically fixedly connected to the support base 2, and the guide brackets are slidably connected to the vertical rod 201 on the same side, which can guide the vertical movement of the vertical rod 201. The protective element 203 is made of rubber and can provide a certain buffer protection effect when the corners of the marble triaxial base collide.

[0028] The implementation principle of a track-limiting marble three-axis base in this application embodiment is as follows: By rotating the handwheel, and through the transmission cooperation between the sprocket and the chain 108, two sets of bidirectional lead screws 101 can be driven to rotate simultaneously in the same direction. The rotation of the bidirectional lead screws 101 can also drive two sets of threaded blocks 102 connected to them to move in opposite directions. Utilizing the sliding cooperation between the storage groove 103 and the sliding block 104, and the hinge cooperation between the connecting beam 106 and the threaded block 102 and the connecting rod 107, the universal wheel 105 at the bottom of the sliding block 104 can be pushed vertically downward until it moves out of the storage groove 103. At this time, the universal wheel 105 will contact the ground to facilitate the movement of the marble three-axis base. After the movement is completed, rotating the handwheel in the opposite direction will cause the universal wheel 105 to be retracted into the storage groove 103. At this time, the support leg on the support base 2 will contact the ground. The marble triaxial base is stably supported. At the same time, as the caster 105 is pushed out of the storage slot 103, the threaded block 102 moves and drives the crossbar 204 to move as well. With the sliding cooperation between the vertical bar 201 and the guide bracket, and the hinged cooperation between the vertical bar 201, the crossbar 204 and the connecting rod 205, the protective part 203 on the fixed plate 202 can be pushed vertically upward at the same time. This protects the corners of the marble triaxial base and prevents them from being damaged by collisions during movement. When the caster 105 is completely pushed out of the storage slot 103, the protective part 203 just completely covers the corners of the marble triaxial base. When the caster 105 is put back into the storage slot 103, the protective part 203 will automatically reset to avoid hindering the use of the marble triaxial base.

[0029] Example 2:

[0030] Based on Example 1, the further improvement of this embodiment is that the protective component 203 has an L-shaped structure design, which makes it easy to fit the corners of the marble triaxial base.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
