Description

Technical Field

[0001] The utility model belongs to the technical field of plate grinding equipment, and in particular relates to a surface grinding device for an alloy plate. Background Art

[0002] Titanium alloy is an alloy metal made of titanium and other metals. It has the advantages of high strength, good corrosion resistance and high heat resistance. It is mainly used in aircraft engines and aircraft bodies.

[0003] Titanium alloy sheet is a metal sheet formed by stamping titanium alloy. After the stamping of titanium alloy sheet is completed, its surface needs to be roughed and finely processed. After the fine processing process, the surface of the sheet needs to be polished with a grinding wheel or a grinding plate. The sheet needs to be clamped and fixed during polishing, which will result in the clamped part of the sheet being unable to be polished directly and requires secondary processing, thereby increasing the polishing time and low work efficiency. To this end, we propose a surface polishing device for titanium alloy sheet. Utility Model Content

[0004] The utility model aims to provide a surface grinding device for alloy plates, so as to solve the problem in the above background technology that the clamped part of the plate cannot be directly ground and needs secondary treatment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a surface grinding device for an alloy plate, comprising a fixed seat, a support frame is fixed to the upper and lower surfaces of the fixed seat, a grinding motor is fixed to the outer side of the support frame, the output shaft of the grinding motor passes through the support frame and a driving shaft is fixed to the end, a grinding plate is fixed to one end of the driving shaft, plug-in grooves are penetrated on both sides of the fixed seat, and a plurality of clamping components are fixed to the inner side of the fixed seat.

[0006] Further preferably, the clamping assembly comprises two vertically symmetrical clamping bars, one end of the clamping bar is fixed to the inner wall of the fixing seat, and two guide bars are fixed on both sides of the other end of the clamping bar.

[0007] Further preferably, the clamping bar is provided with a guide bar whose end is bent in a W shape and the end is vertically upward, and the guide bar is bent upward in an arc shape.

[0008] Further preferably, four fixing rods are fixed on the inner wall of the fixing seat, a positioning rod is slidably mounted on one end of the fixing rod, and a positioning block is fixed on one end of the positioning rod.

[0009] Further preferably, the positioning block is bent in an L-shape and the thickness of the positioning block is less than or equal to the thickness of the plate.

[0010] Further preferably, a positioning hole is provided at the end of the fixing rod connected to the positioning rod, one end of the positioning rod is inserted into the positioning hole and a positioning spring is installed between the fixing rod and the positioning rod.

[0011] Still more preferably, the alloy plate is a titanium alloy plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) When the grinding plate of the utility model rotates and contacts the guide strip that is curved upward in an arc shape, the guide strip will drive the clamping strip and the plate to separate due to the contact of the grinding plate, so that the grinding plate passes between the clamping strip and the plate, and smoothly grinds the clamped position of the plate. The surface of the plate is grinded at one time, and there is no need to perform secondary grinding on the clamped part of the plate, thereby shortening the grinding time and improving work efficiency.

[0014] (2) The utility model applies force directed toward the plate to the positioning rod and the positioning block through the elasticity of the positioning spring, so that the plate ends of the four positioning blocks clamp and position the plate, ensuring that the plate will not move due to the friction of the grinding plate during grinding.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1As shown, a surface grinding device for titanium alloy plates, a support frame 2 is fixed to the upper and lower surfaces of a fixed seat 1, a grinding motor 3 is fixed to the outer side of the support frame 2, the output shaft of the grinding motor 3 passes through the support frame 2 and a driving shaft 5 is fixed to the end, a grinding plate 4 is fixed to one end of the driving shaft 5, and plug-in grooves 6 are penetrated on both sides of the fixed seat 1.

[0022] like Figure 1 and Figure 3 As shown, a plurality of clamping assemblies are fixed on the inner side of the fixing seat 1, and the clamping assemblies include two vertically symmetrical clamping bars 7, one end of the clamping bar 7 is fixed to the inner wall of the fixing seat 1, and two guide bars 8 are fixed on both sides of the other end of the clamping bar 7. The two vertically symmetrical clamping bars 7 are used to clamp the plate to prevent the plate from shaking up and down.

[0023] The holding bar 7 is provided with a guide bar 8 whose end is bent in a W shape and the end is vertically upward. The guide bar 8 is bent upward in an arc shape. When the grinding plate 4 rotates and contacts the guide bar 8 bent upward in an arc shape, the guide bar 8 will drive the clamping bar 7 to separate from the plate due to the contact with the grinding plate 4, so that the grinding plate 4 passes through between the clamping bar 7 and the plate, and smoothly grinds the clamped position of the plate.

[0024] like Figure 2 and Figure 4 As shown, four fixing rods 10 are fixed on the inner wall of the fixing seat 1, a positioning rod 11 is slidably installed at one end of the fixing rod 10, a positioning block 9 is fixed at one end of the positioning rod 11, the positioning block 9 is bent in an L shape and the thickness of the positioning block 9 is less than or equal to the thickness of the plate, and the four positioning blocks 9 are used to position the plate from the end of the plate to ensure that the plate will not shift during grinding.

[0025] A positioning hole is provided at the end where the fixing rod 10 and the positioning rod 11 are connected. One end of the positioning rod 11 is inserted into the positioning hole and a positioning spring 12 is installed between the fixing rod 10. The elasticity of the positioning spring 12 applies a force directed toward the plate to the positioning rod 11 and the positioning block 9, thereby clamping the plate to prevent the plate from moving.

[0026] Working principle: First, insert the plate from the insertion slot 6 on one side of the fixing seat 1, and squeeze the two positioning blocks 9 close to the insertion slot 6 toward the fixing rod 10, so that the plate passes between the two positioning blocks 9, and the plate passes through the insertion slot 6 and is clamped between the two grinding plates 4 until one end of the plate contacts the other two positioning blocks 9. At this time, release the squeezed positioning block 9, so that the four positioning blocks 9 contact the end of the plate to clamp and position the plate. At this time, the upper and lower symmetrical clamping strips 7 clamp the plate from the side of the plate, and finally Then, the device is powered on and started. After the grinding motor 3 is energized, it drives the driving shaft 5 to drive the grinding plate 4 to rotate. The rotating grinding plate 4 slides against the plate to grind the surface of the plate. When the grinding plate 4 contacts the guide bar 8 on the side of the end of the clamping bar 7, the grinding plate 4 will squeeze the guide bar 8, so that the guide bar 8 and the clamping bar 7 are separated from the surface of the plate. At this time, the grinding plate 4 will pass through the clamping bar 7, the guide bar 8 and the plate, and also grind the position of the plate clamped by the clamping bar 7, thereby shortening the grinding time and improving work efficiency.
