Description

Technical Field

[0001] The utility model relates to the supporting of thread rolling equipment, and more specifically, it relates to an oil and chip separation device. Background Art

[0002] Forming thread patterns on the screw rod body is an important process for forming screws. During the process, the residual chips formed when rolling the thread patterns and the used oil often fall along with and adhere to the screw workpiece. Therefore, a more complete process is to separate the oil stains adhering to the screw and the residual chips from the screw workpiece.

[0003] An oil and chip separation device multi-layer spacing adjustment structure disclosed in a Chinese patent with the publication number CN218797183U includes a sieve rod unit. The technical key points are as follows: it includes an upper sieve rod unit, a lower sieve rod unit, and a rear spacing adjustment device. The upper sieve rod unit includes a first bracket arranged on one side of the thread rolling unit, and first rods arranged at intervals on the first bracket. The lower sieve rod unit includes second rods arranged at intervals, and a second bracket arranged on the second rods. Two of the rear spacing adjustment devices are respectively arranged on both sides of the upper sieve rod unit and the lower sieve rod unit. Each of the rear spacing adjustment devices connects the first bracket and the second bracket, and the rear spacing adjustment device is arranged on the side of the lower sieve rod unit close to the thread rolling unit.

[0004] The above technical solution provides the adjustment of the spacing between the upper and lower sieve rod units to realize the adjustment of the sieve leakage gap to meet the sieve leakage of residual chips with different particle sizes. However, the overall height adjustment has the problem of being not convenient enough, and there is also the problem that the sieve leakage gap at the front and rear ends is inconsistent due to inclination; therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide an oil and chip separation device, which has the technical effect of convenient adjustment and eliminates the hidden danger of inconsistent gaps at the front and rear ends of the sieve rod unit.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: An oil and chip separation device includes a frame, a filtering and receiving oil tank arranged on the frame, and a sieve rod unit whose vertical projection is within the opening of the filtering and receiving oil tank. The sieve rod unit includes a plurality of round bars arranged at equal intervals. The front end of the round bar is provided with a conical end head, and a notch is arranged on the lower half of the conical end head. An adjusting rectangular bar is slidably connected along the central axis direction of the round bar in the notch. A variable triangular hole for the largest residual chips to pass through is formed by the cooperation of the adjacent conical end head and the adjusting rectangular bar.

[0007] By adopting the above technical solution, when the present application is working normally, the thread rolling device spits out the processed screws, accompanied by debris and oil, which fall onto the screen rod unit. Under the combined action of the vibration motor and gravity, they move forward along the length directions of multiple round rods. During the forward movement, the oil and small-particle debris fall out through the gaps between adjacent round rods first and enter the filter receiving oil tank. The debris with a particle size larger than the gaps between adjacent round rods falls into the filter receiving oil tank through the variable triangular holes during the process of passing through the variable triangular holes. Finally, the screws from which the oil and debris are separated are discharged. It should be noted that the variable triangular holes of the present application only bear the falling out of the debris with a relatively large particle size, so it is sufficient to meet the requirement of the falling-out frequency. It should also be noted that only by sliding and adjusting the rectangular rod, the size of the variable triangular holes can be controlled, so as to meet the requirements of the sieve leakage of debris with different particle sizes, and it has the technical effect of convenient adjustment. Moreover, the screen rod unit of the present application does not need to be adjusted and can be fixedly assembled, eliminating the hidden danger of inconsistent front and rear end clearances.

[0008] The present utility model is further arranged as follows: the bottom surface of the filter receiving oil tank is inclined, and the end close to the thread rolling device is the low end. A return conduit is arranged at the lowest end of the bottom surface of the filter receiving oil tank; the filter receiving oil tank is provided with an oil filter net for receiving debris and filtering oil. The oil filter net is inclined, and the end close to the thread rolling device is the low end.

[0009] The present utility model is further arranged as follows: the specific number of the screen rod units is two, and the two screen rod units are arranged in a high-low staggered and end-to-end connection manner.

[0010] The present utility model is further arranged as follows: the screen rod unit further includes at least two comb plates, and the comb plates are provided with a plurality of semi-circular grooves for the round rods to be respectively embedded and welded and fixed.

[0011] The present utility model is further arranged as follows: the frame is provided with two side plates oppositely arranged, and both ends of the comb plate are respectively welded and fixed to the two side plates.

[0012] The present utility model is further arranged as follows: the side plates are provided with adjusting stroke grooves, both ends of the adjusting rectangular rod are provided with studs passing through the adjusting stroke grooves, and the studs are in threaded cooperation with locking nuts.

[0013] The present utility model is further arranged as follows: the studs are sleeved with elastic gaskets, and the elastic gaskets are press-fitted between the adjusting rectangular rod and the side plates.

[0014] In summary, the utility model has the following beneficial effects: By simply sliding and adjusting the rectangular rod, the size of the variable triangular hole can be controlled, so as to meet the requirements of sieving for chips with different particle sizes, achieving the technical effect of convenient adjustment. Moreover, the sieve rod unit of this application does not need to be adjusted and can be fixedly assembled to eliminate the hidden danger of inconsistent front and rear end clearances; it facilitates the return flow of the oil fluid for repeated utilization by the thread rolling equipment; it realizes the collection of chips and prevents them from being introduced into the thread rolling equipment along with the oil fluid; it avoids the oil fluid being washed forward along the upper surface of the oil filter screen and eliminates the hidden danger of a large amount of oil fluid splashing out; this application has two positions for larger particle size chips to fall out, ensuring that the frequency requirement for falling out is met; by assembling multiple semi-circular rods into one body through the comb plate, not only can the gap between adjacent semi-circular rods be ensured, but also it facilitates the assembly of this application; the detachable assembly is adopted to facilitate the replacement of the sieve rod unit; the frictional resistance between the adjusting rectangular rod and the side plate is increased to effectively prevent the adjusting rectangular rod from sliding abnormally due to the vibration force.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0021] An oil and chip separation device, as Figure 1 shown, includes a frame 1, a filter connection oil tank 2 fixedly installed on the frame 1, and a sieve rod unit whose vertical projection is within the opening of the filter connection oil tank 2. The sieve rod unit includes a plurality of round rods 3 arranged at equal intervals. The front end of the round rod 3 is formed with a conical end 4. The lower half of the conical end 4 is formed with a notch 5. An adjusting rectangular rod 6 is slidably connected to the notch 5 along the central axis direction of the round rod 3. The adjacent conical end 4 and the adjusting rectangular rod 6 cooperate to form a variable triangular hole 7 for the largest chips to pass through.

[0022] When this application is working properly, the thread rolling equipment spits out the processed screws, accompanied by debris and oil, which fall onto the sieve rod unit. Under the combined action of the vibration motor and gravity, they move forward along the length direction of multiple round rods 3. During the forward movement, the oil and small particle debris fall out through the gaps between adjacent round rods 3 first and enter the filter connection oil tank 2. The debris with a particle size larger than the gaps between adjacent round rods 3 falls into the filter connection oil tank 2 through the variable triangular holes 7 during the process of passing through the variable triangular holes 7, and finally the screws with the separation of oil and debris are discharged. It should be noted that the variable triangular holes 7 of this application only undertake the falling out of debris with a larger particle size, so it is sufficient to meet the frequency requirement of falling out. It should also be noted that as Figure 2 shown, only by sliding and adjusting the rectangular rod 6 can the size of the variable triangular holes 7 be controlled, so as to meet the requirements of different particle size debris passing through the sieve, which has the technical effect of convenient adjustment. And the sieve rod unit of this application does not need to be adjusted and can be fixed assembled to eliminate the hidden danger of inconsistent front and rear end gaps.

[0023] The specific structure of the filter connection oil tank 2 is as follows. As Figure 3 shown, the bottom surface of the filter connection oil tank 2 is inclined, and the end close to the thread rolling equipment is the low end. A return conduit 8 is arranged at the lowest end of the bottom surface of the filter connection oil tank 2, which facilitates the return flow of the oil to the thread rolling equipment for repeated use. The filter connection oil tank 2 is provided with an oil filter net 9 for receiving debris and filtering oil, so as to realize the collection of debris and prevent it from being introduced into the thread rolling equipment along with the oil. It should be noted that the oil filter net 9 is inclined, and the end close to the thread rolling equipment is the low end, so as to prevent the oil from being washed forward along the upper surface of the oil filter net 9 and eliminate the hidden danger of a large amount of oil splashing out.

[0024] To further meet the frequency requirement of the falling out of debris with a larger particle size, as Figure 1 、 Figure 4 shown, the specific number of the sieve rod units is two. The two sieve rod units are arranged in a high-low dislocation and connected end to end, so that this application has two positions for the falling out of debris with a larger particle size, ensuring that the frequency requirement of falling out is met.

[0025] The specific structure of the sieve rod unit is as follows. As Figure 3 、 Figure 4 shown, the sieve rod unit further includes at least two comb plates 10. Multiple semi-circular grooves 11 are machined on the comb plates 10 for the round rods 3 to be embedded and welded and fixed one by one. Thus, the multiple semi-circular rods 11 are assembled into one body through the comb plates 10, which can not only ensure the gaps between adjacent semi-circular rods 11, but also facilitate the assembly of this application.

[0026] It should be noted that as Figure 3 、 Figure 4As shown, there are two side plates 12 oppositely arranged on the frame 1. Both ends of the comb plate 10 are fixed to the two side plates 12 by bolts and nuts, adopting detachable assembly, which provides convenience for replacing the sieve rod unit.

[0027] The specific adjustment structure of the adjusting rectangular bar 6 is as follows. As Figure 3 , Figure 4 shown, the side plate 12 is provided with an adjustment stroke groove 13. Both ends of the adjusting rectangular bar 6 are processed into studs 14 that penetrate through the adjustment stroke groove 13. The studs 14 are threadedly matched with locking nuts 15. After loosening the two locking nuts 15, the adjusting rectangular bar 6 can be slid along the adjustment stroke groove 13, having the technical effects of simple structure and convenient operation.

[0028] It should be noted that, as Figure 3 , Figure 4 shown, an elastic gasket 16 is sleeved on the stud 14. The elastic gasket 16 is interference-fitted between the adjusting rectangular bar 6 and the side plate 12, thereby increasing the frictional resistance between the adjusting rectangular bar 6 and the side plate 12 and effectively preventing the adjusting rectangular bar 6 from sliding abnormally due to vibration force.
