Description

Technical Field

[0001] This utility model belongs to the field of surface treatment technology, and specifically relates to an adjustable surface treatment device. Background Technology

[0002] In the field of machining, there are many challenging problems in processing parts made of specific materials. Take, for example, a hydraulic pump body made of cast aluminum, which is formed using a die-casting and sintering process. The chemical composition of this cast aluminum is characterized by: silicon (Si) content ranging from 8.0 to 10.5%, manganese (Mn) content ranging from 0.2 to 0.5%, magnesium (Mg) content ranging from 0.17 to 0.35%, and aluminum (Al) as the balance; iron content ranging from 0.000 to 0.600% in sand casting and from 0.000 to 0.900% in metal mold casting; copper (Cu) content ≤ 0.1%, zinc (Zn) content ≤ 0.25%, titanium + rare earth (Ti + Zr) content ≤ 0.15%, tin (Sn) content ≤ 0.01%, lead (Pb) content ≤ 0.01%, and the total impurities ≤ 1.4% in metal mold casting. The casting has a tensile strength σb (MPa) ≥ 195 and an elongation δ5 (%) ≥ 1.5. It requires quenching and aging treatment, and the hardness after treatment is 90-120 HBW. During the machining and drilling process, this part is very prone to producing various burrs.

[0003] Traditional surface treatment methods have significant drawbacks:

[0004] 1. Removing burrs with a file: Since the parts are made of aluminum, the file can easily scratch the surface holes of the parts during operation, and will also produce secondary burrs, which poses a high safety risk and is extremely inefficient.

[0005] 2. Simple electric grinding head removal: The electric grinding head rotates too fast, and the speed control is extremely difficult. During use, aluminum chips easily adhere to the grinding head, resulting in unreliable processing quality and low actual utilization rate of the equipment.

[0006] 3. Rotary scraper removal: Given the special location of the part's opening inside the wall cavity, the rotary scraper is completely ineffective.

[0007] It is evident that existing technologies suffer from serious problems such as high labor intensity, low production efficiency, and poor processing quality when dealing with burrs at the machined orifices inside the cavities of parts. There is an urgent need to develop a new, efficient, and reliable surface treatment device. Utility Model Content

[0036] The clamping block 1 has a cuboid structure. A threaded groove is provided on the outer right side of the clamping block 1, and a threaded through hole is provided on the outer left side of the clamping block 1. The threaded through hole is connected to the sliding groove 2. One end of the first handle 4 is screwed into the threaded groove on the clamping block 1, and one end of the second handle 5 is screwed into the threaded through hole on the clamping block 1. The inner end of the second handle 5 extends into the sliding groove 2.

[0037] The first handle 4 and the second handle 5 are located on the same straight line. The ends of the first handle 4 and the second handle 5 away from the clamping block 1 are provided with anti-slip patterns 8, and the ends of the first handle 4 and the second handle 5 away from the clamping block 1 are provided with a through-hole 9.

[0038] A 90° fixing clamping groove 10 is provided on the inner wall of the sliding groove 2 near the first handle 4. The inner walls on both the front and rear sides of the sliding groove 2 are vertical and parallel to the axial direction of the first handle 4 and the second handle 5.

[0039] The positioning block 3 is slidably disposed inside the sliding groove 2 along the axial direction of the first handle 4 and the second handle 5, and the front and rear end faces of the positioning block 3 maintain sliding contact with the front and rear inner walls of the sliding groove 2, respectively. A 90° sliding clamping groove 11 is provided at the end of the positioning block 3 near the first handle 4, and the sliding clamping groove 11 is transitionally connected to the front and rear end faces of the positioning block 3 through two inclined surfaces. The fixed clamping groove 10 is arranged symmetrically with the sliding clamping groove 11.

[0040] A rotating ring 12 is fixedly installed on one end of the inner side of the second handle 5, and the outer surface of the rotating ring 12 is provided with external threads. A rotating groove 13 is provided on the end face of the positioning block 3 near the second handle 5, and the outer opening of the rotating groove 13 is provided with internal threads; the inner diameter of the outer opening of the rotating groove 13 is smaller than the inner diameter of the rotating groove 13. The external threads on the rotating ring 12 are engaged with the internal threads at the outer opening of the rotating groove 13. The rotating ring 12 on the second handle 5 is first screwed into the outer opening of the rotating groove 13, and then passes through the outer opening of the rotating groove 13 and extends into the interior of the rotating groove 13, with the end face of the rotating ring 12 in contact with the inner end face of the transmission groove.

[0041] The transmission rod 6 is a vertically arranged round rod structure. A clamping square rod 14 is fixedly installed at the upper end of the transmission rod 6, and two symmetrical plugs 15 are fixedly installed at the lower end of the transmission rod 6. The two corners of the clamping square rod 14 of the transmission rod 6 are clamped between the sliding clamping groove 11 of the positioning block 3 and the fixed clamping groove 10 of the clamping block 1.

[0042] The cutting tool 7 includes a cutting head 16 and a cutting shank 17, the cutting shank 17 being vertical, and the cutting head 16 being fixedly disposed at the lower end of the cutting shank 17. A insertion groove is provided on the upper end face of the cutting shank 17, and two symmetrical insertion holes 18 are provided inside the insertion groove. The end of the transmission rod 6 away from the clamping block 1 extends into the insertion groove of the cutting shank 17, and two insertion connectors 15 on the transmission rod 6 are inserted into the two insertion holes 18 inside the insertion groove, thereby enabling the transmission rod 6 to engage with the cutting tool 7.

[0043] The cutting head 16, model YT15 E214, possesses extremely high hardness, effectively resisting wear and greatly extending the service life of the cutting tool 7.

[0046] like Figure 11 As shown, the working principle of this utility model is as follows:

[0047] Step 1: Place the positioning block 3 inside the sliding groove 2 of the clamping block 1, so that the sliding clamping groove 11 of the positioning block 3 faces the fixed positioning groove side; screw the first handle 4 into the threaded groove of the clamping block 1, and screw the second handle 5 into the threaded through hole of the clamping block 1, so that the rotating ring 12 at one end of the second handle 5 is first screwed into the outer opening of the rotating groove 13 on the positioning block 3. Continue to rotate the second handle 5, so that the rotating ring 12 on the second handle 5 extends into the rotating groove 13 through the outer opening of the transmission groove, so that the end face of the rotating ring 12 contacts the inner end face of the rotating groove 13. Then, the clamping square rod 14 at the upper end of the transmission rod 6 is inserted into the sliding groove 2 of the clamping block 1, so that the clamping square rod 14 is located between the fixed clamping groove 10 and the sliding clamping groove 11. Then, the second handle 5 is rotated, and the second handle 5 drives the positioning block 3 to move towards the first handle 4 until the sliding clamping groove 11 on the positioning block 3 and the fixed clamping groove 10 on the clamping block 1 clamp the clamping square rod 14 at the upper end of the transmission rod 6, thereby fixing the clamping block 1, the first handle 4, the second handle 5, and the transmission rod 6 together.

[0048] Step two: Two pump body holes are provided on the pump body, located on the same straight line, and connected by a transverse transition hole. The axis of the pump body hole is perpendicular to the axis of the transition hole. The cutter 7 is then placed at the inner end opening of one of the pump body holes, so that the cutter head 16 of the cutter 7 is aligned with the inner end opening of the pump body hole. Then, one end of the connector 15 of the transmission rod 6 is inserted from the outer opening of the other pump body hole until the end of the transmission rod 6 away from the clamping block 1 is inserted into the insertion groove of the cutter bar 17. The two connectors 15 on the transmission rod 6 are inserted into the two insertion holes 18 inside the insertion groove, thus aligning the transmission rod 6 with the cutter 7.

[0049] Step 3: Hold the first handle 4 and the second handle 5 firmly with both hands and rotate them clockwise or counterclockwise two times. After the operation is completed, pull the transmission rod 6 out of the pump body hole and remove the cutter 7. At this time, the burrs at one end of the inner side opening of the pump body hole have been removed.
