Technical Field

[0001] This utility model relates to the field of guide post and guide sleeve technology, and in particular to a universal cylindricity quality inspection device for guide posts and guide sleeves. Background Technology

[0002] In the mold industry, guide pillars and guide bushings are key components used for guidance and positioning. They work together to ensure that the mold is precisely aligned and operates stably during opening and closing.

[0003] After production, guide pillars and guide sleeves need to undergo cylindricity testing to ensure their functionality, durability, and assembly accuracy. Currently, the cylindricity measurement method for guide pillars and guide sleeves is generally to place the guide pillar or guide sleeve flat in the V-groove of a V-block and rotate it, then test its surface with a dial indicator. However, this method has limitations, namely, it is difficult to collect data from deeper parts of the guide pillar, and the data on the dial indicator needs to be observed and measured manually by staff, which is prone to errors. Therefore, it needs to be improved. Utility Model Content

[0028] Reference Figures 1-2 According to an embodiment of the universal cylindricity inspection equipment for guide pillars and guide sleeves of the present invention, it includes a machine base 11, on which a positioning component and a measuring component acting on the workpiece are provided;

[0029] The positioning component is used to position and clamp the guide post or guide sleeve in a vertical state. The positioning component includes a turntable 31 rotatably connected to the machine base 11, and the machine base 11 is equipped with a rotary motor for controlling the rotation of the turntable 31. The turntable 31 is equipped with two V-blocks 32 distributed in opposite directions. The guide post and guide sleeve can be clamped between the V-blocks 32 for positioning.

[0030] In the first embodiment of the positioning component, the V-block 32 is in a fixed state, so that the universal cylindricity inspection equipment for guide posts and guide sleeves is only applicable to one specification of guide post or guide sleeve.

[0031] In the second embodiment of the positioning component, the turntable 31 is also provided with a boss 33, the V-shaped block 32 is slidably connected to the boss 33, and the V-shaped block 32 extends laterally to the left and right sides of the boss 33. The lower side of the V-shaped block 32 is integrally formed with control blocks 34 distributed on the left and right and respectively attached to the left and right sides of the boss 33.

[0032] Mounting plates are provided on the front and rear sides of the boss 33. A second threaded shaft 35 is rotatably connected between the front and rear mounting plates. The second threaded shaft 35 has two opposite threads machined inside, and is threaded to two control blocks 34 located at the same left and right position on the lower side of the two V-blocks 32 respectively.

[0033] In order to facilitate the control of the rotation of the second threaded shaft 35, a rotating shaft 37 is installed on the side of the mounting plate located at the front. A drive gear is installed on the rotating shaft 37. The second threaded shaft 35 extends to the front side of the mounting plate, and a mating gear that meshes with the drive gear is installed on the second threaded shaft 35. A knob is also installed at the front end of the rotating shaft 37.

[0034] The operator can control the rotation of the second threaded shaft 35 by turning the knob, so that the two V-blocks 32 move towards each other and clamp and position the workpiece.

[0035] In order to make the V-shaped block 32 more stable, the control block 34 extends towards the back of the V-shaped block 32, and a reinforcing rib 36 is provided between the control block 34 and the back of the V-shaped block 32.

[0036] The measuring assembly includes a lifting frame 12, and the lifting frame 12 is equipped with a runout measuring assembly 14. The probe in the runout measuring assembly 14 extends laterally so as to press against the side of the workpiece and perform runout detection when the workpiece rotates. It also includes a control device for controlling the left and right position and the up and down position of the lifting frame 12.

[0037] Under the control of the control device, the lifting frame 12 and the runout measuring assembly 14 can be placed inside the guide sleeve clamped by the V-block 32 to perform multiple up-and-down cylindricity tests on the inner wall of the rotating guide sleeve, or placed outside the guide sleeve or guide post clamped by the V-block 32 to perform multiple up-and-down cylindricity tests on the outer wall of the rotating guide post or guide sleeve. It should be noted that when performing cylindricity tests on the outer wall of the guide post and guide sleeve, the runout measuring assembly 14 cannot be lower than the upper edge of the V-block 32 to avoid interference with the V-block 32. If the outer wall at a lower position needs to be measured, the operator needs to slightly loosen the V-block 32 while the turntable 31 is stationary to avoid over-clamping, and then manually drive the guide post or guide sleeve to rotate.

[0038] The control device includes a column 15 mounted on the machine base 11, a horizontal plate 16 mounted on the column 15, a sliding groove 17 provided in the horizontal plate 16, and a slider 18 slidably connected to the sliding groove 17 in the left and right directions, and the lifting frame 12 slidably connected to the slider 18 in the up and down directions.

[0039] The slide groove 17 is rotatably connected to a first threaded shaft 19 threaded to the slider 18, and the horizontal plate 16 is equipped with a horizontal movement motor 20 for driving the first threaded shaft 19.

[0040] The operator can control the rotation of the first threaded shaft 19 via the transverse motor 20, thereby controlling the left and right positions of the slider 18 and the runout measuring assembly 14. In the vertical control scheme for the lifting frame 12 and the runout measuring assembly 14, to reduce errors, the universal cylindricity inspection equipment for guide pillars and guide sleeves has two methods for controlling the vertical positions of the lifting frame 12 and the runout measuring assembly 14:

[0041] 1. The slider 18 is equipped with a lifting motor 21, the output shaft of the lifting motor 21 is equipped with a gear, and the lifting frame 12 is equipped with a rack meshing with the gear.

[0042] 2. The column 15 is slidably connected to the machine base 11, and the machine base 11 is equipped with an electric cylinder (not shown in the figure) for controlling the lifting and lowering of the column 15.

[0043] During the measurement of the cylindricity of the workpiece, the lifting motor 21 first controls the runout measuring assembly 14 to descend to obtain a set of data, and then the electric cylinder 13 controls the runout measuring assembly 14 to descend to obtain a second set of data. By comparing the data, the error is reduced, and the equipment can be self-checked. That is, if the data obtained by the above two methods differ greatly, the cylindricity quality inspection equipment for guide pillars and guide sleeves needs to be checked.

[0044] In addition, the machine tool 11 is equipped with a display screen that is electrically connected to the runout measurement assembly 14.

[0045] It should be noted that the method of the probe in the runout measurement assembly 14 laterally touching the inner or outer wall of the workpiece and transmitting the measured electrical signal to the display screen is existing technology, and the runout measurement assembly 14 can be a dial indicator with a communication connector, which will not be described in detail here.

[0046] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
