Description

Technical Field

[0001] This invention relates to the field of machine tool component technology, and in particular to a machining feed device. Background Technology

[0002] The feed device of a turret milling machine is a type of machining feed device. Existing technology, patent announcement number CN112658772B, discloses a machine tool bed feed device and its control method, providing a turret milling machine machining feed device. This device includes a feed base, in which a horizontal drive mechanism, a horizontal guide mechanism, and a horizontal linkage mechanism are arranged. The horizontal drive mechanism includes two mirror-arranged directional components and a connecting member located between the two directional components. The two directional components are rotatably connected to two opposite sidewalls of a first cavity. The horizontal linkage mechanism, in cooperation with different directional components, adjusts the sliding direction of the feed base. The horizontal linkage mechanism is adapted to insert into the connecting member to link the feed base along the specified path. The horizontal guiding mechanism slides; a supporting part is fixedly connected to the horizontal linkage mechanism, and the supporting part is located on the side into which the connector is inserted; the supporting part is made of flexible material, the supporting part has an internal hollow structure, and the hollow structure is filled with coolant; the supporting part has at least one supporting curved edge, and the supporting curved edge has an overflow port, and the overflow port is normally closed; when the horizontal linkage mechanism is inserted into the connector, the supporting part first contacts the connector and expands outward to cushion between the horizontal linkage mechanism and the connector; after the supporting part expands until the overflow port opens, the coolant can flow through the overflow port to the space between the horizontal linkage mechanism and the connector.

[0003] The aforementioned prior art uses a flexible support section to reduce the frictional resistance between the horizontal linkage mechanism and the connecting parts, thereby reducing the wear of the connecting parts. The support section is filled with coolant, and an overflow port is provided on it to spray out coolant and cool the connecting parts. Although the support section reduces wear on the connecting parts, the friction between the support section and the connecting parts is sliding friction, resulting in significant wear on the support section and requiring frequent replacement; otherwise, the feed accuracy will be affected. When the horizontal linkage mechanism contacts the connecting parts, the support section continuously sprays out internal coolant through the overflow port. While this can cool the connecting parts, the machine tool's feed device is not always operational. That is, when the feed device is idle, the connecting parts do not heat up, but coolant continues to spray out. Moreover, the same amount of coolant is sprayed for different friction temperatures, resulting in unnecessary waste of coolant. Summary of the Invention

[0040] Please see Figure 1 This is a schematic diagram of the overall structure of the machining feed device of the present invention. The machining feed device of this application includes a feed base, a horizontal drive mechanism with a connecting member, a horizontal guide mechanism, a horizontal linkage mechanism 100, a drive assembly, and an anti-friction assembly 200. By replacing the supporting part of the machining feed device in the prior art with the anti-friction assembly 200, and by having the rotating cylinder 220 of the anti-friction assembly 200 directly contact the connecting member, the sliding friction is changed to rolling friction, which solves the technical problem of large sliding friction between the horizontal linkage mechanism 100 and the connecting member in the prior art, and achieves the technical effect of reducing the friction between the horizontal linkage mechanism 100 and the connecting member in the prior art. By connecting the hydraulic pump in series with the motor, the technical problem of coolant waste when the motor is stopped and in standby mode is solved, so that the coolant in the horizontal linkage mechanism 100 is hydraulically pumped only when the connecting member rotates, thereby achieving the technical effect of reducing coolant waste.

[0041] Example 1

[0042] like Figures 1 to 8As shown, this application discloses a machining feed device, including a feed base, a horizontal drive mechanism, a horizontal guide mechanism, a horizontal linkage mechanism 100, and a drive assembly. The horizontal drive mechanism includes two mirror-arranged directional components and a connector located between the two directional components. The two directional components are rotatably connected to two opposite sidewalls of a first cavity. The sliding direction of the feed base is adjusted by the horizontal linkage mechanism 100 cooperating with different directional components. The horizontal linkage mechanism 100 is adapted to be inserted into the connector to link the feed base to slide along the horizontal guide mechanism. The connector is cylindrical, and the contact surface between the horizontal linkage mechanism 100 and the connector is curved.

[0043] The drive assembly includes a motor and a hydraulic pump. The motor provides power to the horizontal drive mechanism, causing the connecting parts to rotate. The motor and the hydraulic pump are connected in series, meaning that the hydraulic pump is controlled by the power supply of the motor. When the motor starts working, the hydraulic pump starts working simultaneously, and when the motor stops working, the hydraulic pump also stops working.

[0044] The horizontal linkage mechanism 100 has a hollow cavity inside, which is filled with coolant. An inlet is provided on the outside, and the inlet is connected to a hydraulic pump through a pipe. The hydraulic pump pumps the coolant into the cavity inside the horizontal linkage mechanism 100.

[0045] The machining feed device of this application also includes an anti-friction component 200. The anti-friction component 200 includes a fixed seat 210 and a rotating drum 220. The fixed seat 210 is fixed on the left and right sides of the horizontal linkage mechanism 100 and is symmetrically arranged. The front end of the fixed seat 210 extends beyond the curved surface of the front end of the horizontal linkage mechanism 100, and a bearing is provided on the opposite inner side for fixing the rotating drum 220.

[0046] The rotating cylinder 220 is a cylindrical tube with a rotating shaft fixed at one end. It is made of rigid material. The axis of the rotating cylinder 220 is parallel to the axis of the connecting piece. The rotating cylinder 220 is horizontally set and closely attached to the curved surface at the front end of the horizontal linkage mechanism 100. Its rotating shaft is rotatably connected to the bearing of the fixed seat 210.

[0047] There are two rotating drums 220, left and right, which are coaxially and symmetrically connected to the bearings of the fixed seats 210 on both sides.

[0048] The horizontal linkage mechanism 100 includes a nozzle 120, which is disposed on the curved surface at the front end of the horizontal linkage mechanism 100. There is a gap between the left and right rotating cylinders 220 for the nozzle 120 to be disposed. The nozzle 120 is located in an unobstructed position between the two rotating cylinders 220, and the nozzle 120 faces the axis of the connecting part. Coolant is sprayed out from the nozzle 120 by a hydraulic pump.

[0049] The horizontal linkage mechanism 100 also includes a rotary groove 110, which is a semi-cylindrical groove, horizontally set at the front curved surface of the horizontal linkage mechanism 100. The diameter of the rotary groove 110 is adapted to that of the rotary cylinder 220, and the rotary cylinder 220 is tightly attached to the rotary groove 110. The length direction of the rotary groove 110 extends through the front curved surface of the horizontal linkage mechanism 100.

[0050] By directly contacting the rotating drum 220 with the connecting member, the sliding friction between the existing support part and the connecting member is changed to rolling friction between the rotating drum 220 and the connecting member, thereby further reducing the risk of wear on the connecting member.

[0051] In the above structure, the nozzle 120 only sprays coolant to cool the connecting parts when the motor is running. However, if the connecting parts are not hot at the beginning of operation, some of the sprayed coolant is easily wasted. In order to further solve the problem of coolant waste and improve the effective utilization rate of coolant, the following improvements are made:

[0052] The machining feed device of this application further includes a first temperature control component 300, which includes a paraffin bag 310, a sieve cylinder 320, a baffle 340 with an air inlet 341, and an air bag 330. The first temperature control component 300 is coaxially fixed between two rotating cylinders 220 and can rotate coaxially with the rotating cylinders 220 as the rotating cylinders 220 rotate. The rotating cylinders 220 are coaxially provided with an air supply channel 221 along the axis. One end of the air supply channel 221 is fixedly connected to the air inlet 341, and the other end passes through the fixed base 210 and is connected to the air pump 500 through the pump pipe.

[0053] The sieve cylinder 320 is a cylindrical shape with open ends and is made of rigid material. The side wall of the sieve cylinder 320 is provided with several circular through holes. The outer diameter of the sieve cylinder 320 is smaller than the diameter of the rotating cylinder 220. The sieve cylinder 320 can limit the maximum diameter of the airbag 330 after expansion, and at the same time, it plays a supporting role for the internal structure of the first temperature control component 300.

[0054] The baffle 340 is a circular rigid plate, there are two of them, fixed at both ends of the screen cylinder 320. The center of the baffle 340 is located on the axis of the screen cylinder 320. The diameter of the baffle 340 is the same as the diameter of the rotating cylinder 220. An air inlet 341 is opened at the center of one side of the baffle 340. The other side of the baffle 340 is fixed to the inside of the rotating cylinder 220.

[0055] The paraffin bag 310 is an elastic cylindrical shape, attached to the outer wall of the sieve cylinder 320, and its two ends are respectively fixed to the edges of the two side baffles 340.

[0056] The airbag 330 is an elastic bladder with one end fixedly connected to the air inlet 341. The airbag 330 is connected to the air pump 500 through the air delivery channel 221, and the air pump 500 can inflate and deflate the airbag 330. After the airbag 330 is inflated, it can fit against the inner wall of the screen cylinder 320.

[0057] The space between the airbag 330 and the paraffin bag 310 is filled with low-melting-point paraffin 350, which has a melting point of 35 degrees Celsius. When the horizontal linkage mechanism 100 is not working, the airbag 330 is in a fully inflated state, and at this time the low-melting-point paraffin 350 is located between the outside of the sieve cylinder 320 and the paraffin bag 310.

[0058] The volume of the low-melting-point paraffin 350 when it is outside the sieve cylinder 320 is such that the outer diameter of the first temperature control component 300 is equal to the outer diameter of the rotating cylinder 220.

[0059] The working steps and principles of the embodiments described above are as follows:

[0060] First, the anti-friction component 200 of the horizontal linkage mechanism 100 contacts the connector. At this time, the connector has not yet rotated. The air bladder 330 inside the first temperature control component 300 is in an inflated state, and the low-melting-point paraffin wax 350 is in a solidified state and located between the outside of the screen cylinder 320 and the paraffin bladder 310. The paraffin bladder 310 is cylindrical with a diameter equal to that of the rotating cylinder 220, supported by the low-melting-point paraffin wax 350. At this time, the nozzle 120 is blocked by the first temperature control component 300. When the motor starts working, the hydraulic pump starts at the same time, and the air bladder 330 contracts under the action of the air pump 500, and the connector begins to rotate. After the connector rotates for a period of time, the temperature of the connector rises to above 35 degrees Celsius, and the low-melting-point paraffin wax 350 begins to melt due to the temperature of the connector. At the same time, the low-melting-point paraffin wax 350 is squeezed into the screen cylinder 320 by the contraction of the paraffin bladder 310. At this time, the nozzle 120 sprays out coolant to cool the connector.

[0061] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0062] This embodiment solves the technical problem of high sliding friction resistance between the horizontal linkage mechanism 100 and the connecting member in the prior art by replacing the supporting part in the prior art with an anti-friction component 200. The rotating cylinder 220 of the anti-friction component 200 directly contacts the connecting member, changing sliding friction into rolling friction. This achieves the technical effect of reducing the friction between the horizontal linkage mechanism 100 and the connecting member in the prior art. By setting the first temperature control component 300, the technical problem of coolant waste when the connecting member temperature is low in the prior art is solved, and the technical effect of the nozzle 120 being automatically opened or closed according to the temperature of the connecting member is achieved.

[0063] Example 2

[0064] Considering the machining feed device in Embodiment 1 above, although it can release coolant when the temperature reaches a certain level, the amount of coolant released is the same for different temperature levels. When the temperature of the connecting parts is low, less coolant is often needed, resulting in coolant waste. Therefore... Figures 2 to 9 As shown, the following improvements are made:

[0065] The machining feed device of this application further includes a second temperature control component 400. The second temperature control component 400 has the same structure as the first temperature control component 300, but differs from the first temperature control component 300 in that the filling material between the paraffin bladder 310 and the air bladder 330 of the second temperature control component 400 is high-melting-point paraffin wax 410, the melting point of which is 55 degrees Celsius. The second temperature control component 400 and the first temperature control component 300 are coaxially fixed between the rotating drums 220 on both sides, and can rotate coaxially under the rotation of the rotating drums 220.

[0066] A baffle 340 without an air inlet 341 is provided between the first temperature control component 300 and the second temperature control component 400.

[0067] There are three sets of combinations of the rotary drum groove 110, the anti-friction component 200, the first temperature control component 300, and the second temperature control component 400, arranged from top to bottom along the arc surface of the horizontal linkage mechanism 100.

[0068] The nozzles 120 are arranged in two vertical rows within the rotary drum groove 110. One row is located behind the first temperature control component 300, and when the first temperature control component 300 is in an expanded state, it can completely block one row of nozzles 120. The other row is located behind the second temperature control component 400, and when the second temperature control component 400 is in an expanded state, it can completely block the other row of nozzles 120.

[0069] The maximum spray volume of each nozzle 120 is a fixed value.

[0070] The working steps and principles of the embodiments described above are as follows:

[0071] First, the anti-friction component 200 of the horizontal linkage mechanism 100 contacts the connector. At this time, the connector has not yet rotated. The air bladders 330 inside the first temperature control component 300 and the second temperature control component 400 are inflated, and the paraffin inside is solidified and located between the outside of the screen cylinder 320 and the paraffin bladder 310. The paraffin bladders 310 of the two temperature control components are cylindrical with a diameter equal to that of the rotating cylinder 220 under the support of the paraffin. At this time, the two rows of nozzles 120 are blocked by the first temperature control component 300 and the second temperature control component 400, respectively. When the motor starts to work, the hydraulic pump simultaneously... When activated, the airbag 330 contracts under the action of the air pump 500, and the connector begins to rotate. After the connector rotates for a period of time, the temperature of the connector rises to above 35 degrees Celsius, and the low-melting-point paraffin wax 350 begins to melt due to the temperature of the connector. At the same time, the paraffin bladder 310 contracts, squeezing the low-melting-point paraffin wax 350 into the sieve cylinder 320. At this time, one row of nozzles 120 is released, spraying out coolant. When the temperature reaches above 55 degrees Celsius, the paraffin bladder 310 of the second temperature control component 400 contracts, and the other row of nozzles 120 is released, thereby increasing the amount of coolant sprayed.

[0072] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0073] This embodiment adds a second temperature control component 400 to Embodiment 1, which further controls the coolant flow and solves the technical problem in the prior art that the coolant sprays out a large amount when the temperature of the connector is low, thus causing waste. It achieves the technical effect of controlling the amount of coolant sprayed out in stages according to the temperature of the connector.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
