Description

Technical Field

[0001] The utility model relates to the field of fixtures, in particular to a machining fixture for a linear optical axis. Background Art

[0002] A linear optical axis is a product that can perform linear motion with the guidance of a sliding bearing. It is widely used in many linear motion systems such as cylinder rods, automatic precision printers, automatic cutting machines, and industrial robots. During the processing of the linear optical axis, a fixture is required to clamp and fix it to facilitate subsequent processing. China has authorized a utility model patent (Announcement No.: CN221774353U) to disclose a processing fixture for the linear optical axis. In this device, a support rod is provided. By starting a second motor, the screw drives the support rod to move left and right, and then the second cylinder pushes the clamp to initially clamp the optical axis. This clamping process does not require manual adjustment and is simple and quick, thereby improving the clamping efficiency of the optical axis. The buffer spring acts as a buffer to prevent excessive clamping force, which causes wear on the optical axis and reduces the processing quality of the optical axis.

[0003] However, there are still some deficiencies in the use of the above-mentioned device: specifically, after the above-mentioned device preliminarily positions the linear optical axis, the structure related to the preliminary positioning will block the surface of the linear optical axis, which not only limits the comprehensive contact of the machining tool with the workpiece surface, but may also interfere with subsequent machining, such as affecting the cutting path, reducing machining accuracy, etc. Therefore, in the prior art, in order to eliminate the influence of such obstruction on the machining process, it is usually necessary to release the preliminary positioning after the secondary positioning, and then perform machining. This operation process is not only cumbersome, but also time-consuming, affecting the machining efficiency. Therefore, a machining fixture for the linear optical axis is proposed to address the above situation. Utility Model Content

The movable end of the cylinder is fixedly connected to a support plate. A second screw hole is provided on the support plate. The bottom end of the connecting rod passes through the base and is threadedly engaged with the second screw hole.

[0026] The following is combined with Figure 1 —6 further details of this application,

[0027] The embodiment of the present application discloses a processing fixture for a linear optical axis. Figure 1 - Figure 6 A processing fixture for a linear optical axis includes a base 1 and an upper clamping seat 3. Both ends of the top of the base 1 are fixedly connected to the lower clamping seat 2. The lower clamping seat 2 is provided with a through hole 201. A support rod 4 is gap-fitted on the through hole 201. The bottom of the support rod 4 is rotatably connected to a connecting rod 5.

[0028] There are two upper clamping seats 3, and both upper clamping seats 3 are provided with a first screw hole 301. The top of the connecting rod 5 passes through the through hole 201 and is threadedly engaged with the first screw hole 301. A pair of cylinders 7 are provided on the bottom surface of the top plate of the base 1. The movable end of the cylinder 7 is fixedly connected to the support plate 6. The support plate 6 is provided with a second screw hole 601. The bottom end of the connecting rod 5 passes through the base 1 and is threadedly engaged with the second screw hole 601.

[0029] The outer walls of the support rod 4 and the connecting rod 5 both have external threads. The support rod 4 is threadedly engaged with the first screw hole 301 through the external threads, and the connecting rod 5 is threadedly engaged with the second screw hole 601 through the external threads.

[0030] Among them, the cylinder 7 is externally connected to a power supply and a switch.

[0031] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The lower clamping seat 2 and the upper clamping seat 3 are both "I"-shaped blocks, and the top of the lower clamping seat 2 and the bottom of the upper clamping seat 3 are both provided with a "V"-shaped groove for placing the linear optical axis.

[0032] Among them, by setting a "V"-shaped groove, the stability of the linear optical axis during initial placement is guaranteed, which facilitates subsequent positioning processing.

[0033] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The "V"-shaped grooves are equipped with rubber pads.

[0034] Among them, by arranging a rubber pad on the "V"-shaped groove, the wear on the surface of the linear optical axis can be reduced when the linear optical axis is positioned.

[0035] Reference Figure 3 、 Figure 4 and Figure 5 The number of the first screw holes 301 and the number of the second screw holes 601 are both four.

[0036] There are eight through holes 201 in total, which are divided into two layers, upper and lower layers, and distributed on the lower clamping seat 2 . The four through holes 201 in each layer are respectively located at the corners of the lower clamping seat 2 .

[0037] The first screw hole 301 is located at a corner of the bottom of the upper clamping seat 3 , and the second screw hole 601 is located at a corner of the top of the support plate 6 .

[0038] Reference Figure 1 and Figure 6, a set of through holes 101 are provided at both ends of the top of the base 1, and each set of through holes 101 has four. The through holes 101 are coaxial with the first screw holes 301.

[0039] Among them, by providing the through holes 101 as the moving channels for the lifting operation of the support rod 4, the upper clamping seat 3 is lifted and lowered, thereby realizing the positioning and releasing of the positioning operation.

[0040] Refer to Figure 2 and Figure 3 , a T-shaped hole is provided at the bottom of the support rod 4, and a T-shaped rod is rotatably fitted in the T-shaped hole. One end of the T-shaped rod passing through the T-shaped hole is connected to the fixed connecting rod 5.

[0041] Among them, through the cooperation of the T-shaped rod and the T-shaped hole, the rotational connection of the connecting rod 5 is realized, which facilitates the assembly with the support plate 6.

[0042] Refer to Figure 1 and Figure 6 , the shape of the base 1 is "U-shaped", and the base 1 has reserved assembly holes.

[0043] Among them, the "U-shaped" base 1 enables the cylinder 7 to be fixed at the bottom of the base 1. The base 1 can provide a certain protection for the cylinder 7. At the same time, the design of the reserved assembly holes facilitates the fixing of the base 1 on the workbench with bolts.

[0044] Working principle: When in use, first fixedly connect the moving end of the cylinder 7 to the support plate 6, then fix the fixed end of the cylinder 7 to the bottom of the base 1 with bolts, then thread the support rod 4 onto the first screw hole 301, and assemble the four support rods 4 one by one. Then align the four support rods 4 with the through holes 201 on the lower clamping seat 2 and insert them, and make them pass through the through holes 101. Then rotate the connecting rod 5, and thread the connecting rod 5 with the second screw hole 601.

[0045] Place the to-be-processed linear optical axis in the through holes 201 on the two lower clamping seats 2, then start the switch of the cylinder 7. The two cylinders 7 work synchronously to make the moving end move downward, thereby making the support plate 6 move downward. The downward movement of the support plate 6 can make the support rod 4 move downward, and then make the upper clamping seat 3 move downward, so as to realize the positioning of the linear optical axis.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
