Description
Technical Field
[0001] The utility model relates to the technical field of ball screws, in particular to a ball screw assembly which is convenient to install and disassemble. Background Art
[0002] Ball screws are devices that convert rotational motion into linear motion with minimal frictional resistance, making them widely used in various industrial equipment. The operating principle of a ball screw mechanism is essentially the same as the transmission principle between a nut and a screw. When the screw can rotate but the nut cannot, rotating the screw limits the nut's rotational freedom because the nut and load slider are connected to a guide component (such as a linear guide or linear bearing). Consequently, the nut and its connected load slider can only move linearly under the influence of the guide component.
[0003] Traditional ball screw assemblies are not convenient for installing and disassembling the screw. When inspecting the connecting ear connecting the screw to the screw above it, the staff needs to use professional tools to first remove the screw support seat at the end of the screw, then remove the screw, and then install it back after the inspection is completed, which is quite troublesome. Utility Model Content
[0004] The technical problem to be solved by the utility model is: to overcome the above problems and provide a ball screw assembly that is convenient to install and disassemble.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a ball screw assembly that is easy to install and disassemble, including a pair of support plates 1 and 2 connected to the same horizontal plane by bolts, a bearing between the pair of support plates is connected to a screw, a connecting hole connected to the screw bearing is provided on the support plate 1, a pressure block is passed through the upper end of the connecting hole and inserted, a positioning assembly for positioning the pressure block is installed on both sides of the support plate 1, a motor is installed at one end of the support plate 2, and the output end of the motor passes through the support plate 2 and is fixedly connected to a sleeve rod inserted into one end of the screw.
[0006] Furthermore, a ball screw nut is vertically installed between a pair of support plates, and a connecting ear is connected to the upper screw of the screw, and the connecting ear is located at the upper end of the ball screw nut and is slidably connected thereto.
[0007] Furthermore, the upper end of the connecting hole is provided with a slot that cooperates with the pressure block and has a width greater than the diameter of the connecting hole. The connecting hole is a semicircular groove, and the lower end of the pressure block is provided with a semicircular groove that is consistent with the diameter of the connecting hole. Positioning holes that cooperate with the positioning assembly are symmetrically provided at both ends of the pressure block.
[0008] Furthermore, the positioning assembly includes a horizontal slide groove that passes through the outside of the support plate, a slider is slidably connected in the horizontal slide groove, and a plug rod is vertically passed through and fixed to the slider. The inner side of the plug rod passes through the side wall and positioning hole of the horizontal slide groove, a pull plate is fixed to the outside of the plug rod, and an iron baffle is installed on the outside of the horizontal slide groove, and a spring is provided between the iron baffle and the slider.
[0009] Furthermore, a ring magnet that cooperates with the iron baffle is fixed on the inner side of the pull plate.
[0010] Furthermore, a square head is provided at one end of the lead screw, and a square groove matching the square head is provided in the sleeve rod.
[0011] The advantages of this utility model compared with the prior art are:
[0012] 1. The pressing block is fixed to the upper end of the connecting hole of the support plate 1 through the positioning assembly, and is connected to the bearing at one end of the screw through the connecting hole and the semicircular groove at the lower end of the pressing block. When it is necessary to inspect the screw and the connecting ear connected to the upper screw, open the positioning assembly and take out the pressing block. Since one end of the screw is connected to the sleeve rod, it is easy to take out the screw without disassembling and installing the support plate 1, which is convenient to use.
[0013] 2. When the positioning assembly is in use, when the lead screw needs to be disassembled, pull the pull plate to disengage the rod from the positioning hole, and then the pressure block can be taken out, so that half of the upper ends of both ends of the lead screw are exposed, making it easier to remove it; when the lead screw needs to be installed, place both ends of the lead screw into the connecting holes respectively, pull the pull plate to move the rod away from the slot, place the pressure block into the slot, loosen the pull plate, and under the action of the iron baffle, slider, and spring, the rod is inserted into the positioning hole to realize the installation of the lead screw.
[0014] 3. An annular magnet that cooperates with the iron baffle is fixed on the inside of the pull plate. The annular magnet and the iron baffle cooperate to fix the position of the pull plate, that is, the position of the fixed insert rod inserted into the positioning hole, to prevent the insert rod from being affected by external factors and leaving the positioning hole, which affects the position of the pressure block and the screw.

[0023] When the present invention is implemented, the sleeve rod 9 is driven by the motor 8 to rotate, thereby rotating the screw 3, so that the connecting ear 5 slides on the ball screw nut 4; the pressure block 6 is fixed to the upper end of the connecting hole 101 by the positioning assembly 7, and the positioning assembly 7 is used to facilitate the installation and disassembly of the pressure block 6. When it is necessary to inspect the screw 3 and the connecting ear 5 connected to the upper screw, the positioning assembly 7 is opened and the pressure block 6 is taken out. Since one end of the screw 3 is plugged into the sleeve rod 9, it is convenient to take out the screw 3, and there is no need to disassemble and install the support plate 1, which is convenient to use.
[0024] Combined with attachment Figure 2-3 The upper end of the connecting hole 101 is provided with a slot 102 with a width greater than the diameter of the connecting hole 101, which cooperates with the pressing block 6. The connecting hole 101 is a semicircular groove, and the lower end of the pressing block 6 is provided with a semicircular groove 601 with the same diameter as the connecting hole 101. The two ends of the pressing block 6 are symmetrically provided with positioning holes 602 that cooperate with the positioning component 7.
[0025] The connecting hole 101 and the semicircular groove 601 are matched with the bearing at one end of the lead screw 3 , and the pressing block 6 is positioned by contacting the bottom wall of the slot 102 at the lower end and matching the positioning assembly 7 at both ends.
