Description

Technical Field

[0001] This disclosure relates to the technical field of auxiliary tooling for honing machines, and more particularly to a positioning tooling for a honing machine. Background Technology

[0002] Honing is a common finishing process for aerospace composite materials and precision metal internal hole parts, used to improve the dimensional accuracy, roundness, and surface finish of internal holes. Existing conventional honing machines require operators to hold the workpiece with both hands, manually align the workpiece's inner hole with the machine tool's cutter shaft, and then manually move the workpiece back and forth, repeatedly pressing it against the cutter shaft to remove the required amount of material. However, manual alignment is inaccurate, and misalignment or deviation between the workpiece's inner hole and the cutter shaft can easily occur, resulting in defects such as taper, ellipticity, and uneven honing of the inner hole. This leads to a high scrap rate for precision parts and is extremely labor-intensive and unsustainable: honing a single piece requires continuous hand-holding and back-and-forth pushing; prolonged operation easily causes hand tremors and fatigue, further amplifying machining errors. The pushing force, stroke, and speed cannot be standardized by different operators and under different working conditions, resulting in poor consistency in the surface finish and dimensions of the inner holes of batches of parts, failing to meet the requirements of mass production of aerospace precision parts. Furthermore, manually holding the workpiece close to the high-speed rotating cutter shaft increases the risk of bumps, scratches, and hand pinching.

[0003] Therefore, it is necessary to propose a honing machine tool positioning fixture to at least partially solve the problems existing in the prior art. Utility Model Content

[0004] This disclosure aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, this disclosure proposes a positioning fixture for a honing machine tool.

[0006] In view of this, a honing machine tool positioning fixture is proposed according to an embodiment of the present disclosure, comprising: Support unit, installed on honing machine tool; A first mounting bracket is used to mount the part to be honed. The first mounting bracket has a first through hole, through which the cutter shaft of the honing machine tool passes and is inserted into the part to be honed. A clamping part is provided on the first mounting bracket to clamp and position the honing part on the first mounting bracket so that the central axis of the honing inner hole of the honing part coincides with the central axis of the cutter shaft. The drive unit is mounted on the support unit, and the first mounting bracket is connected to the drive unit. The drive unit drives the first mounting bracket to reciprocate along the axis of the cutter shaft.

[0007] In one feasible implementation, the support portion includes: The first plate is fixed to the aforementioned honing machine. The second plate is vertically connected to the first plate, and the drive motor of the drive unit is mounted on the second plate. The third plate has its side connected to the side of the second plate, and its bottom connected to the first plate. The fourth plate is connected to the third plate. The extension direction of the fourth plate is consistent with the axial direction of the cutter shaft. The actuation component of the drive unit is disposed on the fourth plate. The drive motor is used to drive the actuation component to drive the first mounting bracket to reciprocate along the axial direction of the cutter shaft.

[0008] In one feasible implementation, the above-mentioned action component includes: An eccentric wheel mechanism is provided, wherein the output shaft of the drive motor passes through the second plate and the eccentric wheel mechanism is sleeved on the end of the output shaft; A drive shaft, one end of which is connected to the eccentric wheel mechanism; A pushing mechanism, the other end of the aforementioned drive shaft is connected to the aforementioned pushing mechanism, and the aforementioned pushing mechanism is connected to the aforementioned first mounting bracket; A guiding mechanism is provided on the fourth plate. The guiding direction of the guiding mechanism is consistent with the axial direction of the cutter shaft. The guiding mechanism is used to guide the pushing mechanism to move along the guiding direction.

[0009] In one feasible implementation, the aforementioned propulsion mechanism includes: A connecting block is provided with a connecting rod along the axial direction of the output shaft, and the other end of the transmission shaft is sleeved on the connecting rod. A push rod, one end of which is connected to the end of the connecting block away from the eccentric wheel mechanism, and the other end of which is connected to the first mounting bracket. The guide mechanism is provided with a guide groove along the axial direction of the cutter shaft, and the push rod is inserted into the guide groove.

[0010] In one feasible implementation, multiple push rods are provided and evenly distributed at one end of the connecting block away from the eccentric wheel mechanism. The number of guide mechanisms corresponds to the number of push rods, and each push rod cooperates with the corresponding guide mechanism.

[0011] In one feasible implementation, the first mounting bracket includes: A connecting plate is connected to the other end of the aforementioned push rod, and the connecting plate has the aforementioned first through hole; A mounting plate is provided on the aforementioned connecting plate, and the aforementioned clamping part is mounted on the aforementioned mounting plate; A baffle is provided on the top of the mounting plate. When the honing inner hole of the part to be honed is inserted into the cutter shaft, the part to be honed is located above the baffle.

[0012] In one feasible implementation, the clamping part includes: A clamping plate is hinged to the mounting plate. The clamping plate has a second through hole. When the clamping plate rotates to press against the end face of the part to be honed, the cutter shaft passes through the second through hole. A pressure plate, hinged to the top of the connecting plate, is used to rotate to press against the top of the part to be honed; A fastener is used to fix the clamping plate and the pressure plate at the clamping position.

[0013] In one feasible implementation, the above-mentioned fastener includes: The locking screw and nut are provided.

[0015] In one feasible implementation, the honing machine tool positioning fixture further includes: The reinforcing rib has one end connected to the third plate and the other end connected to the fourth plate.

[0016] Compared to the prior art, this disclosure offers at least the following advantages: The honing machine positioning fixture provided in this embodiment includes a support portion, a first mounting bracket, a clamping portion, and a driving portion. The support portion can be mounted on the honing machine. The first mounting bracket can hold the part to be honed and has a first through hole through which the honing machine's cutter shaft passes. When the part to be honed is mounted on the first mounting bracket, the cutter shaft is inserted into the honing inner hole of the part, aligning the central axis of the inner hole with the central axis of the cutter shaft, thus positioning the part. The clamping portion secures the part to be honed to its final positioning position. The driving portion drives the first mounting bracket to reciprocate along the axis of the cutter shaft for honing operations. This setup ensures that during the honing process, the inner hole of the part to be honed can be fed linearly back and forth relative to the cutter axis of the honing machine with a fixed stroke, frequency, and trajectory. This allows the inner hole to be honed to make uniform contact with the cutter axis, achieving hole enlargement and grinding, ensuring the coaxiality and roundness of the inner hole machining, improving machining accuracy, stability, and consistency, and also increasing the automation level of the honing operation, reducing labor costs and labor intensity, and improving processing efficiency.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0020] like Figures 1 to 5 As shown, according to an embodiment of this disclosure, a honing machine tool positioning fixture 100 is provided, comprising: a support portion 110, mounted on a honing machine tool 200; a first mounting bracket 120 for mounting a part 300 to be honed, the first mounting bracket 120 having a first through hole 1211 through which the cutter shaft of the honing machine tool 200 passes and is inserted into the part 300 to be honed; a clamping portion 130 disposed on the first mounting bracket 120 for clamping and positioning the part 300 to be honed on the first mounting bracket 120, such that the central axis of the inner hole to be honed of the part 300 to be honed coincides with the central axis of the cutter shaft; and a driving portion 140 mounted on the support portion 110, the first mounting bracket 120 being connected to the driving portion 140, the driving portion 140 driving the first mounting bracket 120 to reciprocate along the axial direction of the cutter shaft.

[0021] It is understood that the honing machine positioning fixture 100 provided in this embodiment includes a support part 110, a first mounting bracket 120, a clamping part 130, and a drive part 140. The support part 110 can be mounted on the honing machine 200. The first mounting bracket 120 can mount the part to be honed 300, and the first mounting bracket 120 has a first through hole 1211 through which the cutter shaft of the honing machine 200 passes. When the part to be honed 300 is mounted on the first mounting bracket 120, the cutter shaft is inserted into the honing inner hole of the part to be honed 300, so that the central axis of the honing inner hole coincides with the central axis of the cutter shaft, thereby achieving positioning of the part to be honed 300. The clamping part 130 is used to clamp and fix the part to be honed 300 at the final positioning position. The first mounting bracket 120 is driven by the drive unit 140 to reciprocate along the axis of the cutter shaft for honing. This configuration ensures that during the honing process, the inner hole of the part 300 to be honed can reciprocate linearly relative to the cutter shaft of the honing machine 200 with a fixed stroke, frequency, and trajectory. This allows the inner hole to be honed to make uniform contact with the cutter shaft, achieving hole enlargement and grinding, ensuring the coaxiality and roundness of the inner hole, improving machining accuracy, stability, and consistency, and increasing the automation level of the honing operation, reducing labor costs and labor intensity, and improving processing efficiency.

[0022] For example, such as Figure 5 The diagram shows a schematic structure of a part 300 to be honed. The part is cylindrical in shape and has multiple through holes along its axial direction. Honing is performed on the multiple through holes. The part can be assembled into the honing machine tool positioning fixture 100. The through holes to be honed are inserted into the cutter shaft for positioning before the honing operation is performed.

[0023] In some examples, such as Figures 1 to 5 As shown, the support 110 includes: a first plate 111 fixed to the honing machine 200; a second plate 112 connected vertically to the first plate 111, with the drive motor 141 of the drive unit 140 mounted on the second plate 112; a third plate 113, with its side connected to the side of the second plate 112 and its bottom connected to the first plate 111; and a fourth plate 114 connected to the third plate 113, the extension direction of the fourth plate 114 being consistent with the axial direction of the cutter shaft, the actuation component 142 of the drive unit 140 disposed on the fourth plate 114, and the drive motor 141 driving the actuation component 142 to drive the first mounting bracket 120 to reciprocate along the axial direction of the cutter shaft.

[0024] Understandably, the support portion 110 may be provided with a first plate 111, a second plate 112, a third plate 113, and a fourth plate 114. The first plate 111 is horizontally fixed to the honing machine 200. The bottom of the second plate 112 is connected to the first plate 111, and the second plate 112 is perpendicular to the first plate 111, supporting the drive motor 141 of the drive portion 140. The side of the third plate 113 is connected to the side of the second plate 112, and the bottom of the third plate 113 is connected to the first plate 111. The side of the fourth plate 114 is perpendicularly connected to the side of the third plate 113, and the extension direction of the fourth plate 114 is parallel to the axis of the tool shaft, supporting the actuation assembly 142 of the drive portion 140. The first mounting bracket 120 is connected to the actuation assembly 142. The actuation component 142 is connected to the drive motor 141. The drive motor 141 drives the actuation component 142 to move along the axis of the cutter shaft. In turn, the actuation component 142 drives the first mounting bracket 120 and the honing part 300 clamped and fixed by the clamping part 130 to reciprocate along the axis of the cutter shaft, thereby performing the honing operation.

[0025] In some examples, such as Figures 1 to 3 As shown, the aforementioned actuation component 142 includes: an eccentric wheel mechanism 1421, the output shaft of the drive motor 141 passing through the second plate 112, and the eccentric wheel mechanism 1421 sleeved on the end of the output shaft; a transmission shaft 1422, one end of which is connected to the eccentric wheel mechanism 1421; a pushing mechanism 1423, the other end of which is connected to the pushing mechanism 1423, and the pushing mechanism 1423 is connected to the first mounting bracket 120; and a guide mechanism 1424, disposed on the fourth plate 114, the guiding direction of the guide mechanism 1424 being consistent with the axial direction of the cutter shaft, and the guide mechanism 1424 being used to guide the pushing mechanism 1423 to move along the guiding direction.

[0026] It is understood that the drive motor 141 is fixed to one side of the second plate 112, and the output shaft of the drive motor 141 passes through the second plate 112 and is located on the other side of the second plate 112. The power of the drive motor 141 is transmitted to the push mechanism 1423 through the eccentric wheel mechanism 1421 and the transmission shaft 1422, so as to push the first mounting bracket 120 to move through the push mechanism 1423. Among them, the eccentric wheel mechanism 1421 has a connecting shaft on the side opposite to the second plate 112. One end of the transmission shaft 1422 is rotatably connected to the connecting shaft, and the other end of the transmission shaft 1422 is rotatably connected to the push mechanism 1423. With this configuration, the inner hole of the eccentric wheel mechanism 1421 used to connect the output shaft and the geometric center of the transmission shaft 1422 are not on the same axis. When the output shaft drives the inner hole to rotate at a constant speed, due to the center offset, the connecting shaft reciprocates alternately at the high point and low point of the eccentric wheel mechanism 1421, thereby driving the push mechanism 1423 to perform reciprocating linear motion along the axis of the cutter shaft. Furthermore, the guiding mechanism 1424 can guide the pushing mechanism 1423 to ensure that the pushing mechanism 1423 can reciprocate stably along the axis of the cutter shaft, thereby improving reliability and ensuring that during the honing operation, the inner hole of the part to be honed 300 can be linearly reciprocated relative to the cutter shaft of the honing machine tool 200 with a fixed stroke, frequency and trajectory, so that the inner hole to be honed is in uniform contact with the cutter shaft, realizing hole enlargement and grinding, ensuring the coaxiality and roundness of the inner hole machining, and improving machining accuracy, machining stability and machining consistency.

[0027] In some examples, such as Figures 1 to 3 As shown, the aforementioned pushing mechanism 1423 includes: a connecting block 14231, a connecting rod 14232 provided along the axial direction of the output shaft, and the other end of the transmission shaft 1422 sleeved on the connecting rod 14232; a pushing rod 14233, one end of the pushing rod 14233 connected to the end of the connecting block 14231 away from the eccentric wheel mechanism 1421, and the other end of the pushing rod 14233 connected to the first mounting bracket 120; the guiding mechanism 1424 is provided with a guide groove along the axial direction of the cutter shaft, and the pushing rod 14233 is inserted into the guide groove.

[0028] It is understood that the pushing mechanism 1423 is provided with a connecting block 14231, and the pushing rod 14233 is connected to the connecting block 14231, with the axial direction of the pushing rod 14233 being consistent with the axial direction of the cutter shaft. The connecting block 14231 is provided with a connecting rod 14232 along the axial direction of the output shaft, and the other end of the transmission shaft 1422 is rotatably connected to the connecting rod 14232. Under the action of the eccentric wheel mechanism 1421, the connecting shaft reciprocates alternately at the high and low points of the eccentric wheel mechanism 1421. At the same time, one end of the transmission shaft 1422 rotates relative to the connecting shaft, and the other end rotates relative to the connecting rod 14232. This causes the transmission shaft 1422 to swing as a whole, pushing the connecting block 14231 to move forward linearly or pulling the connecting block 14231 to move backward linearly. This, in turn, drives the first mounting bracket 120 to reciprocate along the axial direction of the cutter shaft via the pushing rod 14233. The guide mechanism 1424 can be fixedly connected to the fourth plate 114, and the guide mechanism 1424 has a guide groove along the axial direction of the cutter shaft. The push rod 14233 can be inserted into the guide groove. The radial displacement of the push rod 14233 is restricted by the guide groove, so that the push rod 14233 moves only along the axial direction of the cutter shaft, thereby ensuring that the movement direction of the honing part 300 is accurate and reliable, and improving stability.

[0029] In some examples, multiple push rods 14233 are provided and are evenly distributed on one end of the connecting block 14231 away from the eccentric wheel mechanism 1421. The number of guide mechanisms 1424 corresponds to the number of push rods 14233, and each push rod 14233 cooperates with the corresponding guide mechanism 1424.

[0030] It is understood that multiple push rods 14233 can be arranged in parallel on the connecting block 14231 to evenly distribute the pushing or pulling force applied to the first mounting bracket 120, and each push rod 14233 has a corresponding guide mechanism 1424 for guidance, ensuring that each push rod 14233 moves along the axial direction of the cutter shaft, thereby improving reliability. For example, there are two push rods 14233 and two guide mechanisms 1424.

[0031] In some examples, such as Figure 1 and Figure 2 As shown, the first mounting bracket 120 includes: a connecting plate 121 connected to the other end of the push rod 14233, the connecting plate 121 having the first through hole 1211; a mounting plate 122 disposed on the connecting plate 121, the clamping part 130 being mounted on the mounting plate 122; and a baffle 123 disposed on the top of the mounting plate 122. When the honing inner hole of the workpiece 300 to be honed is inserted into the cutter shaft, the workpiece 300 to be honed is located above the baffle 123.

[0032] It is understood that the connecting plate 121 is connected to the push rod 14233, so that the push rod 14233 drives the connecting plate 121 to reciprocate along the axis of the cutter shaft. The connecting plate 121 may have a first through hole 1211 so that the cutter shaft can pass through the first through hole 1211. The mounting plate 122 is attached to the side of the connecting plate 121 away from the push rod 14233, and the mounting plate 122 is provided with a bent section, which is perpendicular to the connecting plate 121 to form a mounting surface. The baffle 123 can be installed on the top of the mounting surface. When installing the part to be honed 300, the inner hole of the part to be honed 300 can be inserted into the cutter shaft to ensure that the inner hole to be honed and the cutter shaft are coaxial, and the baffle 123 can support and limit the position of the part to be honed 300.

[0033] In some examples, such as Figure 1 and Figure 2 As shown, the clamping part 130 includes: a clamping plate 131, hinged to the mounting plate 122, the clamping plate 131 having a second through hole 1311, and the cutter shaft passing through the second through hole 1311 when the clamping plate 131 rotates to press against the end face of the part 300 to be honed; a pressure plate 132, hinged to the top of the connecting plate 121, for rotating to press against the top of the part 300 to be honed; and a fixing member 133 for fixing the clamping plate 131 and the pressure plate 132 at the clamping position.

[0034] Understandably, after inserting the workpiece 300 to be honed into the cutter shaft, the clamping plate 131 can be rotated so that it presses against the end of the workpiece 300 away from the connecting plate 121. At this time, the second through hole 1311 of the clamping plate 131 corresponds to the first through hole 1211, ensuring that the cutter shaft can pass through the second through hole 1311 when the workpiece 300 reciprocates along the axis of the cutter shaft, thus preventing interference and collision between the clamping plate 131 and the cutter shaft, which could cause damage. Simultaneously, the pressure plate 132 can be rotated so that it presses against the top of the workpiece 300, thus clamping and positioning the workpiece 300 through the clamping plate 131 and the pressure plate 132. After the pressure plate 132 and clamping plate 131 are installed in place, the clamping plate 131 and pressure plate 132 can be fixed in the clamping position by the fastener 133 to ensure that the position of the workpiece 300 to be honed relative to the axis of the cutter shaft is fixed during the honing operation, thus ensuring the honing quality.

[0035] In some examples, such as Figure 2As shown, the aforementioned fastener 133 includes: a locking screw 1332 and a nut 1331. The pressure plate 132 is provided with a bent edge, and the bent edge has a third through hole. The nut 1331 is disposed on the bent edge and communicates with the third through hole. The clamping plate 131 has a fourth through hole. When the pressure plate 132 presses against the top of the part to be honed 300 and the clamping plate 131 presses against the end face of the part to be honed 300, the bent edge is located on the side of the clamping plate 131 away from the connecting plate 121, and the positions of the third through hole and the fourth through hole correspond to each other. The locking screw is screwed onto the nut 1331 and inserted into the third through hole and the fourth through hole in sequence.

[0036] It is understandable that when the pressure plate 132 is pressed against the top of the part 300 to be honed and the clamping plate 131 is pressed against the side of the part 300 to be honed, the positions of the third through hole and the fourth through hole correspond, thereby connecting the nut 1331, the third through hole and the fourth through hole. By tightening the locking screw 1332, the locking screw 1332 can be pressed against the pressure plate 132 and the clamping plate 131, thereby fixing the clamping plate 131 and the pressure plate 132 in the clamping position, so as to ensure that the part 300 to be honed is fixed relative to the axis of the cutter shaft during the honing operation, ensuring the honing quality, and the fixing operation is simple and quick, and the structure of the fixing part 133 is simple and reliable.

[0037] In some examples, such as Figure 1 As shown, the honing machine tool positioning fixture 100 also includes: a second mounting bracket 150 connected to the third plate 113; and a controller 160 disposed on the second mounting bracket 150 for controlling the operating status of the drive motor 141.

[0038] It is understandable that the honing machine tool positioning fixture 100 may also be equipped with a second mounting bracket 150 and a controller 160. Specifically, the second mounting bracket 150 may be installed on the upper part of the third plate 113, and the controller 160 may be installed on the second mounting bracket 150 and located on the same side as the drive motor 141. The controller 160 may be electrically connected to the drive motor 141 so as to control the start and stop of the drive motor 141, the speed and direction of the output shaft, and the honing operation according to the honing operation requirements, so as to realize that the workpiece 300 to be honed makes linear reciprocating feed relative to the cutter axis of the honing machine tool 200 with a fixed stroke, frequency and trajectory.

[0039] In some examples, such as Figure 1 As shown, the honing machine tool positioning fixture 100 also includes a reinforcing rib 170, one end of which is connected to the third plate 113 and the other end of which is connected to the fourth plate 114.

[0040] It is understandable that the outline of the reinforcing rib 170 can be a right triangle, with one right-angled side connected to the third plate 113 and the other right-angled side connected to the fourth plate 114. The reinforcing rib 170 improves the connection strength between the third plate 113 and the fourth plate 114 and reduces the amount of connection deformation, thereby ensuring that the feed direction of the first mounting bracket 120 is consistent with the axis direction of the cutter shaft, thus improving reliability.
