[0040] As described in the background of the present application, the valve sleeve or valve core of the hydraulic control valve is provided with a flow channel along the axial direction, and needs to be honed during processing to improve the workpiece size and the accuracy of the flow channel.

[0041] The inventors of the present application have discovered that it is currently inconvenient to fix the workpiece (valve sleeve or valve core) on the machine table, which affects the processing efficiency of the workpiece.

[0042] In order to solve the above problems, the inventors of this application have proposed the technical solution of this application, and the specific embodiments are as follows:

[0043] Figure 1 is a schematic diagram of a workpiece in the present invention, Figure 2 Schematic diagram of a portable honing tool in an embodiment of the present utility model. Figure 3 Schematic diagram of the fixed shaft in the embodiment of the present utility model, Figure 4 This is a schematic diagram of a support base in an embodiment of the present utility model. Figure 5 Schematic diagram of a pressing block in an embodiment of the present invention.

[0044] like Figures 1 to 5 As shown, the portable honing tool of this embodiment includes: a fixed shaft 1, a support seat 2 and a pressing block 3.

[0045] The fixed shaft 1 is fixed on the machine table of the processing machine tool.

[0046] The fixed shaft 1 is provided with an accommodating groove 11 and an accommodating channel 12 .

[0047] The accommodating channel 12 of the fixed shaft 1 is arranged along the radial direction of the fixed shaft 1 and penetrates the fixed shaft 1 in the radial direction.

[0048] The accommodating groove 11 extends from the top surface of the fixed shaft 1 along the axial direction of the fixed shaft 1 to the accommodating channel 12 , so that the accommodating groove 11 is communicated with the accommodating channel 12 .

[0049] The support seat 2 is detachably arranged on the fixed shaft 1 and passes through the accommodating channel 12 of the fixed shaft 1 .

[0050] The pressing block 3 is provided with a through hole 31 .

[0051] The pressing block 3 is disposed on the top surface of the fixed shaft 1 , and the position of the through hole 31 of the pressing block 3 corresponds to the position of the accommodating groove 11 of the fixed shaft 1 .

[0052] In this embodiment, the honing fixture is used with a fixed shaft 1 secured to the machine table via connectors. The workpiece 10 to be machined (such as a valve sleeve or valve core) is inserted into the receiving groove 11 of the fixed shaft 1. The bottom end of the workpiece 10 rests on the support seat 2, and the top end of the workpiece 10 extends beyond the top surface of the fixed shaft 1. A pressure block 3 is secured to the fixed shaft 1 via connectors such as bolts. The pressure block 3 compresses the workpiece 10, securing it to the machine table. The machine tool's honing head extends through the through hole 31 of the pressure block 3 to perform honing on the flow channel of the workpiece 10.

[0053] From the above, it is not difficult to find that the portable honing tool of this embodiment is fixed on the machine platform by setting a fixed shaft, a support seat and a pressure block. The fixed shaft is fixed on the machine platform, and the fixed shaft is provided with a receiving groove and a receiving channel. The support seat is arranged in the receiving channel of the fixed shaft. The workpiece is passed through the receiving groove of the fixed shaft and abuts on the support seat. The pressure block is arranged on the fixed shaft to press the workpiece. When the portable honing tool of this embodiment is used, the workpiece (valve sleeve or valve core) is inserted into the receiving groove of the fixed shaft, the bottom end of the workpiece abuts on the support seat, and the pressure block is fixed on the top end of the fixed shaft to press the workpiece so that the workpiece is clamped and fixed on the machine platform. The honing head extends from the process hole of the pressure block into the flow channel of the workpiece to hone the flow channel of the workpiece. The tool has the advantages of simple structure, easy installation and use, and low cost, which improves the processing efficiency of the workpiece.

[0054] Optionally, in the portable honing tool in this embodiment, the fixed shaft 1 is provided with a mounting plane 13 on the circumferential side wall, and the fixed shaft 1 is provided with a first threaded hole at the mounting plane 13 .

[0055] A limiting side plate 21 is provided on one side of the support base 2 , and a mounting through hole 211 is provided on the limiting side plate 21 of the support base 2 .

[0056] When the support seat 2 is fixed, the limiting side plate 21 of the support seat 2 is abutted against the mounting plane 13 of the fixed shaft 1, so that the support seat 2 is positioned on the fixed shaft 1, and then the fixing screw 4 passes through the mounting through hole 211 of the support seat 2 and engages with the first threaded hole of the fixed shaft 1, so that the support seat 2 (limiting side plate 21) is detachably fixed on the fixed shaft 1.

[0057] Further, such as Figure 4 As shown, in the portable honing tool in this embodiment, the outer side surface of the limiting side plate 21 of the support seat 2 and the outer side surface of the other side of the support seat 1 opposite to the limiting side plate 21 are both arc-shaped. After the support seat 2 is fixed, the outer side surface of the support seat 2 and the circumferential side surface of the fixed shaft 1 form a smooth arc surface.

[0058] Optional, such as Figure 4 As shown, in the portable honing tool in this embodiment, a U-shaped groove 22 is provided on one side of the support seat 2.

[0059] In this embodiment, when the workpiece to be machined is short, the support base is positioned with the opening of the U-shaped groove facing downward. During machining, the bottom end of the workpiece rests against the other side of the U-shaped groove. When the workpiece to be machined is long, the support base is removed and reinstalled in reverse. Even when the U-shaped groove is positioned with the opening facing upward, the bottom end of the workpiece extends into the U-shaped groove and rests against the bottom plate of the U-shaped groove. This allows the honing tool to adapt to machining workpieces of different lengths and specifications, and switching between them is convenient.

[0060] Furthermore, in the portable honing tool of this embodiment, the support seat 2 is provided with limiting protrusions 23 on both upper and lower sides of the bottom plate of the U-shaped groove 22.

[0061] A limiting slot 101 is provided at the bottom of the workpiece 10 .

[0062] When the workpiece is being processed, it is inserted into the receiving groove of the fixed shaft, and the limiting protrusion of the support seat is inserted into the limiting groove of the workpiece to prevent the workpiece from rotating during processing.

[0063] Furthermore, in this embodiment of the portable honing tool, the support base 2 is provided with a process hole 24 extending through the bottom plate of the U-shaped groove 22. The position of the process hole 24 of the support base 2 corresponds to the position of the flow channel of the workpiece 10. During machining of the workpiece 10, the honing head can be inserted into the process hole 24 of the support base 2 without damaging the support base.

[0064] Optionally, in the portable honing tool of this embodiment, a fixing plate 14 is provided at the top end of the fixed shaft 1 , a fixing hole is provided on the circumferential outer side of the fixing plate 14 , and the fixed shaft 1 is fixed to the machine platform through the fixing plate 14 .

[0065] The pressure block 3 is fixed to the fixed plate 14 of the fixed shaft 1 through a connecting piece.

[0066] Optionally, in the portable honing tool of this embodiment, the side walls of the pressing block 3 are provided with sliding grooves 32 , and the pressing block 3 can be slidably arranged on the slider of the machine through the sliding grooves 32 .

[0067] A notch 33 is provided on one side of the pressing block 3 , through which the top of the workpiece can be observed.

[0068] Furthermore, in the portable honing tool of this embodiment, a limiting step 15 is provided on the circumferential side wall of the fixed shaft 1, and a positioning hole (not shown) extending axially upward is provided at the bottom end of the fixed shaft 1.

[0069] The limiting step 15 and the positioning hole of the fixed shaft 1 are used to cooperate with the machine platform to facilitate the installation and positioning of the fixed shaft 1 on the machine platform.

[0070] In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may mean that the first feature and the second feature are in direct contact, or the first feature and the second feature are in indirect contact through an intermediate medium.

[0071] Furthermore, when a first feature is “above,” “above,” or “above” a second feature, it may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. When a first feature is “below,” “below,” or “below” a second feature, it may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
