Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

As shown in fig. 1, the six grooves 11 and the six interference protrusions 12 on the inner race 10 are uniformly distributed on the circumferential side wall thereof, and when the inner race 10 is positioned in the circumferential direction during conveying, there is a great difficulty in positioning from the shaft hole and the arc interference surface 13, therefore, the central line of two opposite grooves 11 is selected as a positioning reference, and as shown in fig. 1, a dashed line a is selected as a positioning reference, it can be understood by those skilled in the art that three such positioning references, namely three such dashed lines a, exist on one inner race 10, and it is only necessary to satisfy one of the positioning references as a standard to position the inner race 10 in the circumferential direction, so that the postures of the inner races 10 can be kept consistent.

In one embodiment, a star sleeve 10 transport apparatus is provided to enable transport of the star sleeve 10 for picking or retrieving the star sleeve 10.

The star sleeve 10 conveying device comprises the posture adjusting mechanism 100, so that the posture of the star sleeve 10 in the conveying process can be adjusted by the posture adjusting mechanism 100, the postures of the star sleeves 10 are kept consistent, and the star sleeves 10 can be conveniently taken or picked.

It should be noted that taking or picking up the star sleeve 10 can be achieved by grabbing or picking up the star sleeve in the manner of an existing manipulator or the like, and the star sleeve is not described herein again because the star sleeve belongs to the prior art.

As shown in fig. 2 and 3, the posture adjustment mechanism 100 includes a conveying member 110, a first guide member 120, and a posture adjustment assembly 130.

The conveying member 110 may be a conveyor belt or the like, and can convey the star sleeve 10 placed thereon in a first direction (as shown in a direction B in fig. 2 and 3).

It is understood that the first direction may be any direction designed according to actual site conditions and transportation requirements, for example, the first direction may be from left to right, or from right to left, and may not be limited.

The first guide 120 may be in the form of a guide plate or a guide strip, and the first guide 120 may be disposed on one side of the conveying member 110 in a threaded manner or a clamping manner.

As shown in fig. 4, the posture adjustment assembly 130 includes a pressing member 131 and a moving member 132.

Specifically, the pressing member 131 is disposed opposite to the first guide 120 at an interval so that a conveyance path is formed between the pressing member 131 and the first guide 120, and the pressing member 131 can be reciprocally moved in a direction perpendicular to the first direction.

More specifically, when the pressing member 131 moves in a direction perpendicular to the first direction toward the direction approaching the first guide 120, the distance between the pressing member 131 and the first guide 120 becomes smaller, so that the inner race 10 passing through the conveying passage can be collided, and then the pressing member 131 pushes the inner race 10 passing through the conveying passage to move toward the direction approaching the first guide 120 until the inner race 10 is collided with the first guide 120, that is, the pressing member 131 and the first guide 120 are collided with the opposite sides of the inner race 10, respectively, so that the clamping effect of the inner race 10 is achieved, and at this time, the inner race 10 cannot be conveyed along with the conveying member 110. When the pressing member 131 moves in a direction perpendicular to the first direction toward a direction away from the first guide member 120, the distance between the pressing member 131 and the first guide member 120 becomes large, so that the gripped inner star 10 can be released, so that the inner star 10 can be conveyed in the first direction in synchronization with the conveying member 110.

Alternatively, the pressing member 131 may be in the form of an air cylinder or a hydraulic cylinder, etc., which is reciprocally moved in the first direction by means of a telescopic form, in conjunction with the first guide member 120, thereby achieving clamping or unclamping of the inner race 10.

Wherein, the moving member 132 is connected with the pressing member 131 in a transmission manner, and when the pressing member 131 pushes the star-shaped sleeve 10 to move towards the direction close to the first guide member 120 so that the star-shaped sleeve 10 is in interference fit with the first guide member 120, the moving member 132 can drive the pressing member 131 to reciprocate in the first direction, and the pressing member 131 moves in the first direction due to the fact that the first guide member 120 is stationary, so that the arc interference surface 13 of the star-shaped sleeve 10 in contact with the pressing member 131 is subjected to friction force in the tangential direction, and further the star-shaped sleeve 10 rotates around the central axis of the star-shaped sleeve 10, so that the posture of the star-shaped sleeve 10 is adjusted in the conveying process to be positioned in the circumferential direction, the star-shaped sleeve 10 does not need to be conveyed to a separate positioning mechanism, the structure is simplified, and the cost is reduced.

It can be understood that, the moving member 132 drives the pressing member 131 to reciprocate in the first direction, which means that the moving member 132 can drive the pressing member 131 to move in the first direction and the opposite direction of the first direction.

Alternatively, if the arc length of one arc interference surface 13 of the inner race 10 is S, the moving stroke of the moving member 132 in the first direction is L. So, after pressing member 131 and first guide 120 and carrying out the centre gripping to star cover 10, moving member 132 drives and presses member 131 and remove L in the first direction for star cover 10 rotates around the central axis of self, because S < L < 2S, and then make star cover 10 can rotate to make two relative grooves 11 correspond with pressing member 131 and first guide 120 respectively, even make star cover 10 rotate to make one of them dotted line A be perpendicular with first direction mutually, thereby can accomplish star cover 10 location and attitude adjustment on the circumferencial direction in transportation process.

Wherein, L can be 1.1S, 1.2S, 1.3S, 1.4S, 1.5S, 1.6S, 1.7S, 1.8S, 1.9S, and can be adaptively adjusted according to the actual clamping condition of the inner race 10, and only the inner race 10 needs to be rotated to enable one of the imaginary lines a to be perpendicular to the first direction. L is preferably 1.5S so that the friction experienced by the inner race 10 ensures that the inner race 10 rotates to one of the imaginary lines a perpendicular to the first direction.

Wherein, moving member 132 drives compressing component 131 and reciprocating motion in the first direction, can drive compressing component 131 through the flexible of cylinder or pneumatic cylinder and move in the first direction, also can drive compressing component 131 through the cooperation of gear and rack and move in the first direction, can also drive compressing component 131 through linear electric motor driven form and move in the first direction.

In addition, in order to ensure that the pressing member 131 can accurately push the inner race 10 when moving in the direction perpendicular to the first direction toward the first guide member 120. As shown in fig. 4, optionally, the posture adjustment mechanism 100 further includes a first detection element 140, so that whether the inner race 10 is conveyed to the conveying channel between the first guide 120 and the pressing member 131 is detected by the first detection element 140, and the first detection element 140 is electrically connected to the pressing member 131, so that when the first detection element 140 detects that the inner race 10 is conveyed to the conveying channel, the pressing member 131 is controlled to move towards the first guide 120 along the direction perpendicular to the first direction, so that the inner race 10 in the conveying channel can be accurately clamped in an interference manner by the pressing member 131 and the first guide 120, and thus, the occurrence of misoperation or delayed operation is avoided.

The first detecting element 140 may be a position sensor, a photoelectric switch, or other conventional component capable of detecting the presence or absence of the inner race 10. Also, the first detecting member 140 may be disposed at an upstream position of the pressing member 131 in the first direction.

Further, the posture adjustment assembly 130 further includes a mounting seat 133 so that the pressing member 131 can be mounted on the mounting seat 133.

As shown in fig. 4, specifically, the mounting seat 133 is provided with a sliding portion 1331 extending along the first direction, and the pressing member 131 is in sliding fit with the sliding portion 1331, so that when the moving member 132 drives the pressing member 131 to reciprocate in the first direction, the sliding fit between the sliding portion 1331 and the pressing member 131 is utilized, so as to guide and limit the movement of the pressing member 131, so that the pressing member 131 moves more accurately and smoothly in the first direction, and further, the posture of the inner race 10 can be accurately adjusted.

Wherein, sliding part 1331 can be the form of slide rail, correspondingly, can set up the spout with slide rail matched with on compressing tightly piece 131. The mounting base 133 can be fixed on the gantry by screwing, welding or clamping.

During the actual conveying process, the star sleeve 10 after the posture adjustment is prevented from deflecting during the conveying process to cause the posture change. As shown in fig. 3, the posture adjustment mechanism 100 may further include a second guide 150 and a spacing adjustment assembly 160.

The second guide 150 is disposed on the other side of the conveying member 110, and the second guide 150 is disposed downstream of the pressing member 131 and opposite to at least a portion of the first guide 120 along the first direction, that is, the second guide 150 is spaced apart from a portion of the first guide 120 to form a guide channel.

And, the first guide 120 and the second guide 150 are both in transmission connection with the spacing adjustment assembly 160, so that the spacing between the first guide 120 and the second guide 150 is adjustable, and thus, after the star sleeve 10 completes posture adjustment in the conveying channel, the star sleeve enters the guide channel formed by the first guide 120 and the second guide 150 at a relative interval, the spacing between the first guide 120 and the second guide 150 is adjusted by the spacing adjustment assembly 160, so that the width of the guide channel is adjusted, the width of the guide channel is matched with the outer diameter of the star sleeve 10, and then the star sleeve 10 can be limited from deflecting in the conveying process, so that the star sleeve 10 can keep the adjusted posture for conveying. Moreover, the distance between the first guide member 120 and the second guide member 150 is adjusted by the distance adjusting assembly 160, so that the guide channel can be compatible with the conveying requirements of the star-shaped sleeves 10 with different sizes, and the universality is strong.

The second guide 150 may be in the form of a guide plate or a guide bar.

The distance between the first guide member 120 and the second guide member 150 is adjusted by the distance adjusting assembly 160, and can be pushed in the first direction perpendicular to the first direction by a cylinder or a hydraulic cylinder, or driven in the first direction perpendicular to the first direction by the cooperation of a gear and a rack, or can be linked by a linear motor driving mode.

In particular, in the embodiment of the present application, the distance adjusting assembly 160 includes a servo motor, a screw rod having a first screw thread and a second screw thread, a first nut sleeved on the first screw thread, and a second nut sleeved on the second screw thread. And the first handed thread is opposite to the second handed thread in hand.

Specifically, the lead screw extends along the perpendicular to first direction, thereby utilize the transmission of servo motor and lead screw to be connected and can drive the central axis corotation or the reversal of lead screw wire winding rod self, thereby when lead screw corotation and reversal, make first nut and second nut draw close each other or keep away from along the perpendicular to first direction, combine first nut and first guide 120 to adopt modes such as spiro union or joint to be connected, second nut and second guide 150 adopt modes such as spiro union or joint to be connected, and then drive first guide 120 and second guide 150 and draw close each other or keep away from along the perpendicular to first direction, and then adjust the width of guide way.

In addition, in order to ensure the uniformity of the width of the guide channel. As shown in fig. 3, the spacing adjustment assembly 160 further includes a first guide rail 170 and a second guide rail 180 that are disposed along the first direction and are spaced apart from each other.

Specifically, the first rail 170 and the second rail 180 both extend in a direction perpendicular to the first direction. Both ends of the first guide 120 are in guiding engagement with the first rail 170 and the second rail 180, respectively, and both ends of the second guide 150 are in guiding engagement with the first rail 170 and the second rail 180, respectively. Thus, the first guide rail 170 and the second guide rail 180 can be used for guiding the first guide piece 120 and the second guide piece 150 to be close to or away from each other, so that the first guide piece 120 and the second guide piece 150 can stably and accurately move along the first direction perpendicular to the first direction, inclination or deviation cannot occur, the uniformity of the width of the guide channel is ensured, the star-shaped sleeve 10 can be effectively limited to deflect when being conveyed in the guide channel, and the star-shaped sleeve 10 can be conveyed in a posture kept after adjustment.

The two ends of the first guide 120 are respectively in guiding fit with the first guide rail 170 and the second guide rail 180, and may be implemented in a sliding fit manner or a rolling fit manner.

The two ends of the second guide 150 are respectively in guiding fit with the first guide rail 170 and the second guide rail 180, and may be implemented in a sliding fit manner or a rolling fit manner.

Further, when the inner race 10 is conveyed on the conveyor 110, there is a problem that they are stacked on each other, which affects the adjustment of the posture.

It will be appreciated that, in order to ensure that the mutual movement of the first guide 120 and the second guide 150 does not cause interference with the attitude adjustment assembly 130, the connection between the first guide 120 and the first and second rails 170, 180 may also have intermediate elements, for example, the guiding engagement between the first guide 120 and the first and second rails 170, 180 may be achieved indirectly through intermediate connection plates; likewise, the connection between the second guide 150 and the first 170 and second 180 rails may also present intermediate elements, such as may be accomplished indirectly through intermediate connection plates for guiding engagement between the second guide 150 and the first 170 and second 180 rails.

As shown in fig. 3 and 5, optionally, the posture adjustment mechanism 100 further includes a material distribution assembly 190.

Specifically, along the first direction, the material distributing assembly 190 is arranged at the upstream of the posture adjusting assembly 130, so that the material distributing assembly 190 is used for arranging the star sleeves 10 on the conveying piece 110 at equal intervals, the star sleeves 10 are conveyed into the conveying channel at equal intervals to adjust the posture, the posture adjustment among the star sleeves 10 can be achieved without interfering with each other, and the accuracy of the posture adjustment is ensured.

As shown in fig. 3 and 5, the material distributing assembly 190 includes a first blocking member 191, a second blocking member 192, a second detecting element 193, and a third detecting element 194 electrically connected to each other.

The first blocking member 191 and the second blocking member 192 are spaced in the first direction, and both the first blocking member 191 and the second blocking member 192 can block or release the inner race 10 on the conveying member 110, that is, both the first blocking member 191 and the second blocking member 192 have a blocking state and a releasing state.

Alternatively, the first stop 191 may take the form of a gripping stop, in which case the first stop 191 may be a first jaw by which the sleeve 10 is gripped to limit the transport of the sleeve 10 with the transport member 110 in the first direction so that the sleeve 10 remains in the gripped position, and the sleeve 10 can continue to be transported on the transport member 110 in the first direction when the first jaw releases the sleeve 10 to free the sleeve 10; the first blocking member 191 may also be in the form of an interference block, in which case the first blocking member 191 may be a first blocking cylinder that extends against the inner race 10 to restrict the inner race 10 from being conveyed with the conveying member 110 in the first direction such that the inner race 10 remains in the position of interference, and, when the first blocking cylinder is retracted to clear the inner race 10, the inner race 10 can continue to be conveyed on the conveying member 110 in the first direction.

Alternatively, the second stop 192 may take the form of a gripping stop, in which case the second stop 192 may be a second jaw by which the inner race 10 is gripped to limit the transport of the inner race 10 with the transport member 110 in the first direction so that the inner race 10 remains in the gripped position, and when the second jaw releases the inner race 10 to clear the inner race 10, the inner race 10 can continue to be transported on the transport member 110 in the first direction; the second blocking member 192 may also be in the form of an interference block, in which case the second blocking member 192 may be a second blocking cylinder that extends against the inner race 10 to restrict the inner race 10 from being conveyed along the conveying member 110 in the first direction such that the inner race 10 remains in the position of interference, and, when the second blocking cylinder is retracted to clear the inner race 10, the inner race 10 can continue to be conveyed along the conveying member 110 in the first direction.

Meanwhile, the first blocking member 191 is disposed close to the posture adjustment assembly 130 relative to the second blocking member 192, that is, when the inner race 10 moves on the conveying member 110 along the first direction, the inner race 10 passes through the position where the second blocking member 192 is disposed, then passes through the position where the first blocking member 191 is disposed, and then passes through the posture adjustment assembly 130 to perform posture adjustment.

The second detecting element 193 and the third detecting element 194 are disposed at an interval along the first direction, and the third detecting element 194 is disposed close to the posture adjustment assembly 130 relative to the second detecting element 193, that is, when the inner race 10 moves along the first direction on the conveying member 110, the inner race 10 passes through a position where the second detecting element 193 is disposed, passes through a position where the third detecting element 194 is disposed, and then passes through the posture adjustment assembly 130 to adjust the posture.

In particular, it is detected by the second detection element 193 whether the inner sleeve 10 is blocked at the first blocking member 191, i.e. it is detected by the second detection element 193 whether the inner sleeve 10 is conveyed to the first blocking member 191 and blocked by the first blocking member 191 in the blocking state. The third detecting element 194 is used to detect whether the inner race 10 passes through the detection position corresponding to the third detecting element 194.

More specifically, when the second detecting element 193 detects that the star sleeve 10 is blocked at the first blocking element 191, that is, the forwardmost star sleeve 10 (hereinafter, referred to as the first star sleeve 10) is conveyed in the first direction to be blocked by the first blocking element 191, the second blocking element 192 is switched from the release state to the blocking state, so that the star sleeve 10 adjacent to the first star sleeve 10 (hereinafter, referred to as the second star sleeve 10) is blocked by the second blocking element 192, and then the first blocking element 191 is switched from the blocking state to the release state, so that the first star sleeve 10 is conveyed in the first direction on the conveying element 110, when the third detecting element 194 detects the first star sleeve 10, that is, when the third detecting element 194 detects that the first star sleeve 10 passes through the detecting position corresponding to the third detecting element 194, the first blocking element is switched from the release state 191 to the blocking state, the release state is switched to the blocking state, and the second blocking state is switched to the blocking state, so that the star sleeve 10 is conveyed in the same posture as the conveying element 194, and the star sleeve conveying elements 130 are adjusted to ensure that the star sleeve conveying elements 130 are not to be in the same posture, so that the conveying elements 130 are not to be in the same manner, so that the conveying elements 130 are switched to ensure that the star sleeve conveying elements are not to be in the same posture of the star sleeve conveying elements.

The second detecting element 193 and the third detecting element 194 may be a photoelectric switch, a proximity switch or other existing elements capable of detecting the position of the inner race 10.

It should be noted that the electrical connection mode may be limited connection through a wire, or may be connection through a wireless mode such as bluetooth transmission, and there may also be an intermediate element, for example, a central control unit such as a single chip is provided, and interaction and transmission of signals are realized by using the central control unit.

It should be noted that upstream refers to a side of the conveying member 110 closer to the feeding mechanism, and correspondingly, downstream refers to a side of the conveying member 110 farther from the feeding mechanism. Specifically, when the conveying member 110 is conveyed from left to right, upstream refers to a side closer to the left, and downstream refers to a side closer to the right.

Compared with the existing mode of circumferentially positioning the inner race 10 by combining the vibrating disk with the vision system, the posture adjusting mechanism 100 of the embodiment has a simpler structure, can adjust the posture of the inner race 10 synchronously in the conveying process, can save the cost, can reduce the occupied space, and can reduce the failure rate.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the present application, unless expressly stated or limited otherwise, the first feature may be directly on or directly under the second feature or indirectly via intermediate members. Also, a first feature "on," "above," and "over" a second feature may be directly on or obliquely above the second feature, or simply mean that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to," "disposed on," "secured to," or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. Further, when one element is regarded as "fixed transmission connection" another element, the two elements may be fixed in a detachable connection manner or in a non-detachable connection manner, and power transmission can be realized, such as sleeving, clamping, integrally-formed fixing, welding and the like, which can be realized in the prior art, and is not burdensome. When an element is perpendicular or nearly perpendicular to another element, it is desirable that the two elements are perpendicular, but some vertical error may exist due to manufacturing and assembly effects. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

It should also be understood that in interpreting the connection or positional relationship of the elements, although not explicitly described, the connection and positional relationship are to be interpreted as including a range of error that should be within an acceptable range of deviation from the particular values as determined by one skilled in the art. For example, "about," "approximately," or "substantially" may mean within one or more standard deviations, without limitation.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
