AI Technical Summary
The fixed cylindrical brush head of the existing tube cleaning device cannot effectively clean the inner hole of the tube and the bottom of the linear groove at the same time, resulting in incomplete cleaning, laborious operation, and rapid wear of the brush head, requiring frequent replacement.
The expansion brush head is made of aluminum alloy and uses a pneumatic expansion method. It uses rubber rings and beryllium bronze self-made parts as seals. The bristles fit tightly with the inner hole of the tube and the bottom of the linear groove. The expansion and retraction of the brush head are controlled by the air source, so as to achieve flexible operation and wide wiping.
It achieves comprehensive cleaning of the inner hole of the tube and the bottom of the linear groove, reducing the labor required for operation and the frequency of brush head replacement, improving the cleaning effect and reducing labor intensity.

Description
TECHNICAL FIELD
[0001] The utility model belongs to the barrel scrubbing mechanical equipment field, more particularly to a kind of for barrel scrubbing expansion brush head. BACKGROUND
[0002] Barrel scrubbing is the device for scrubbing long-hole barrel part, and the brush head matched with the barrel scrubbing device in the past is all fixed cylinder brush head, and when scrubbing barrel with linear slot, the fixed cylinder brush head in the past can only contact the position of barrel inner hole, cannot contact linear slot bottom part, resulting in excessive scrubbing of barrel inner hole, and linear slot bottom part cannot be scrubbed, to ensure that barrel inner hole and linear slot bottom part are cleaned, the size of brush head is selected to be slightly larger than the inner diameter of barrel, and it is very laborious to insert brush head into barrel mouth, if the size of brush head is selected to be close to the inner diameter of barrel, it is slightly labor-saving to insert brush head into barrel mouth, but it can result in unclean barrel scrubbing.So the expandable brush head with replaceable brush hairs of various forms is designed, which not only solves the smoothness of insertion and removal of brush head, but also ensures that each part of barrel can be scrubbed clean. SUMMARY
[0003] 1.Purpose of invention
[0004] The present application is an expansion brush head for barrel scrubbing, aluminum alloy material is used as expansion main body material, pneumatic expansion mode is adopted, rubber ring and beryllium bronze self-made parts are combined as sealing parts, brush head is made according to the shape of barrel inner hole section, suitable materials are selected, the structure of expansion main body is designed, and brush hairs closely matched with barrel inner hole are made, the expansion brush head is flexible in action, reliable in performance, simple in operation, wide in cleaning range, labor intensity is reduced, and barrel scrubbing effect is improved, and it is suitable for scrubbing various barrels with linear slot.
[0005] 2.Technical solution
[0006] According to the structure diagram of expansion brush head for barrel scrubbing device, self-made processing parts include: barrel scrubbing device connecting sleeve, rear cover, check valve, brush, plunger, front cover, expansion brush head main body, safety valve and connecting sleeve two, and purchased parts include rubber O-ring seal.
[0007] The expansion brush head for barrel scrubbing of the present application is mainly different from fixed cylinder brush head:
[0008] Fixed cylinder brush head:
[0009] 1), barrel inner hole is excessively scrubbed, and linear slot bottom part cannot be scrubbed.
[0010] 2), after scrubbing several times, brush head will be worn, and if scrubbing is carried out without replacing brush head, scrubbing effect cannot be achieved.
[0011] 3), the size of the brush head is larger than the inner diameter of the barrel, and it is difficult to insert the brush head into the barrel; if the size of the brush head is close to the inner diameter of the barrel, it is slightly easier to insert the brush head into the barrel, but the barrel is not cleaned.
[0012] The expanded brush head:
[0013] 1), the brush (e) has high and low brush parts matched with the inner hole of the barrel and the bottom of the linear groove, and is closely matched with the inner hole of the barrel and the bottom of the linear groove, so that the inner hole of the barrel and the bottom of the linear groove are cleaned.
[0014] 2), after several times of cleaning, the brush will be worn out, but because the air source always expands the plunger outward, the friction between the brush and the inner wall of the barrel is constant, so the brush does not need to be replaced frequently.
[0015] 3), when the air source of the barrel cleaning device is not turned on, the plunger is in the retracted state, and the diameter of the brush head is much smaller than the inner diameter of the barrel, so that the brush head can be smoothly inserted into the barrel.
[0016] 3. Beneficial effects
[0017] By expanding the brush head, the operation is flexible, the performance is reliable, the operation is simple, the wiping range is wide, the labor intensity of the operator is greatly reduced, and the barrel cleaning effect is improved. BRIEF DESCRIPTION OF DRAWINGS

[0026] The following description fully illustrates the specific embodiments of the present application to enable a person skilled in the art to practice and reproduce the same.
[0027] 1. Component parts
[0028] According to the structure diagram and parts diagram of the barrel scrubbing device inflatable brush head, a connecting sleeve (1), a rear cover (2), a one-way valve (3), a brush (5), a plunger (6), a front cover (7), an inflatable brush head body (8), a safety valve (9), a connecting sleeve two (10), and a standard part of an external purchase are processed and manufactured.
[0029] 2. Component connection part of the inflatable brush head
[0030] 2.1 The connecting sleeve (1) of the barrel scrubbing device is connected and fixed with the barrel scrubbing device in a screw tightening manner.
[0031] 2.2 The inflatable brush head body (8) is a main body of the barrel scrubbing device inflatable brush head, which connects other main components with the main body to form the inflatable brush head structure, and the safety valve (9) is installed at the end of the inflatable brush head body (8).
[0032] 2.3 The rear cover (2) and the front cover (7) are mainly used for fixing the brush (5) to prevent the brush (5) from moving.
[0033] 2.4 The plunger (6) is fixed on the four plunger (6) in a screw tightening manner, and the rubber O-ring seal (4) is connected with the inflatable brush head body (8) to play a sealing role. Under the action of air pressure, the brush (5) expands outwardly along with the plunger (6), thereby achieving the effect of expansion.

After the brush (5) enters the barrel, it is tightly combined with the barrel hole and the bottom of the linear groove.
[0035] 3. Through the component connection and external connection of the inflatable brush head, the expansion function of the brush head is realized
[0036] 3.1 Check whether the safety valve (9) is in a pressure relief state. If not, the pressure of the safety valve (9) needs to be discharged, so that the inflatable brush head maintains the smallest diameter.
[0037] 3.2 Use screws to fix the four-petal brush (5) on the four plungers (6).
[0038] 3.3 Connect the expanding brush head with the barrel cleaning device, and tightly connect the air inlet hole of the one-way valve (3) with the air source of the barrel cleaning device to ensure that the use of the air source of the barrel cleaning device is controlled at 0.7 Mpa.
[0039] 3.4 According to the test condition, set the pressure of the adjusting safety valve (9), and install the safety valve in place.
[0040] 3.5 In the state that the air source of the barrel cleaning device is not opened, insert the barrel cleaning device connected with the expanding brush head into the barrel, and insert the high and low brush parts of the brush (5) into the barrel corresponding to the bottom of the linear groove of the inner hole of the barrel.
[0041] 3.6 Open the air source, and enter the cavity through the one-way valve (3); under the action of the air pressure, the plunger (6) expands outward without reaching the adjusting pressure of the safety valve (9), and the brush (5) is closely combined with the inner hole of the barrel and the bottom of the linear groove under the action of the plunger (6).
[0042] 3.7 Start the operation mode of the barrel cleaning device, and the expanding brush head rubs along the direction of the linear groove.
