Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

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 transportation, it is difficult to position both from the shaft hole and from the arc interference surface 13, so the center lines of the two opposite grooves 11 are selected as positioning references, as shown in fig. 1, and the dotted line a is selected as a positioning reference, and it can be understood by those skilled in the art that three such positioning references exist on one inner race 10, that is, three such dotted lines a exist, and only one of the positioning references is required 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 may be achieved by grabbing or picking up in a manner of an existing manipulator or the like, and the star sleeve is not described herein again because it 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 in the form of a conveyor belt or the like, and is capable of conveying the inner race 10 placed thereon in a first direction (as shown in the 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 a distance so that a conveyance path is formed between the pressing member 131 and the first guide 120, and the pressing member 131 can reciprocate 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 in transmission connection with the pressing member 131, and, when the pressing member 131 pushes the inner race 10 to move towards the direction close to the first guide member 120 so that the inner race 10 is in interference fit with the first guide member 120, the pressing member 131 can be driven to reciprocate in the first direction by the moving member 132, because the first guide member 120 is static and the pressing member 131 moves in the first direction, the arc interference surface 13 where the inner race 10 contacts with the pressing member 131 is subjected to the friction force in the tangential direction, and further the inner race 10 rotates around the central axis of the inner race 10, so that the posture of the inner race 10 is adjusted in the conveying process to perform the positioning in the circumferential direction, the inner race 10 does not need to be conveyed to an independent 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 abutting 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 sensing element 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.

The sliding portion 1331 may be in the form of a sliding rail, and accordingly, a sliding groove matched with the sliding rail may be formed on the pressing member 131. The mounting seat 133 can be fixed on the gantry bracket by screwing, welding or clamping.

During the actual conveying process, the change of the posture caused by the deflection of the star-shaped sleeve 10 after the posture adjustment is completed during the conveying process is avoided. As shown in fig. 3, the posture adjustment mechanism 100 may further include a second guide 150 and a spacing adjustment assembly 160.

Wherein, the second guiding element 150 is disposed at the other side of the conveying element 110, and along the first direction, the second guiding element 150 is disposed downstream of the pressing element 131 and is disposed opposite to at least a portion of the first guiding element 120, that is, the second guiding element 150 is disposed opposite to a portion of the first guiding element 120 at an interval to form a guiding 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.

Specifically, 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 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 or keep away from each other along perpendicular to first direction, combine first nut and first guide 120 to adopt modes such as spiro union or joint to be connected, the second nut adopts modes such as spiro union or joint to be connected with second guide 150, and then drive first guide 120 and second guide 150 and draw close or keep away from each other along perpendicular to first direction, and then adjust the width of direction channel.

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 guide the first guide piece 120 and the second guide piece 150 to be close to or far 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 the inner race and the outer race 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 interfere with the attitude adjustment assembly 130, the connection between the first guide 120 and the first 170 and second 180 rails may also have intermediate elements, for example, the guiding engagement between the first guide 120 and the first 170 and second 180 rails 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 to interfere with the inner race 10 to limit the inner race 10 from being transported along the transport member 110 in the first direction such that the inner race 10 remains in the position of interference, and when the first blocking cylinder contracts to clear the inner race 10, the inner race 10 can continue to be transported along the transport 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 stop 192 may also be in the form of an interference stop, in which case the second stop 192 may be a second stop cylinder that extends to abut the inner race 10 to limit the transfer of the inner race 10 with the transfer member 110 in the first direction so that the inner race 10 remains in the position of interference, and when the second stop cylinder is retracted to clear the inner race 10, the inner race 10 can continue to be transferred on the transfer 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.

Specifically, whether the inner race 10 is blocked at the first blocker 191 is detected by the second detection element 193, that is, whether the inner race 10 is conveyed to the first blocker 191 and blocked by the first blocker 191 in the blocked state can be detected by the second detection element 193. 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, each of the inner sleeves 10 is conveyed on the conveying member 110 in the first direction, when the first blocking member 191 is in the blocking state and the second blocking member 192 is in the releasing state, when the second detecting element 193 detects that the inner sleeve 10 is blocked at the first blocking member 191, that is, the front-most inner sleeve 10 (hereinafter referred to as the first inner sleeve 10) is conveyed in the first direction to be blocked by the first blocking member 191, the second blocking member 192 is switched from the releasing state to the blocking state, so that the inner sleeve 10 (hereinafter referred to as the second inner sleeve 10) adjacent to the first inner sleeve 10 is blocked by the second blocking member 192, and then the first blocking member 191 is switched from the blocking state to the releasing state, so that the first inner sleeve 10 is conveyed on the conveying member 110 in the first direction, and when the third detecting element 194 detects the first inner sleeve 10, that the third detecting element 194 detects that the first inner sleeve 10 passes through the detecting position corresponding to the third detecting element 194 Then, the first blocking member 191 is switched from the release state to the blocking state, and the second blocking member 192 is switched from the blocking state to the release state, and the process is repeated, so that the star sleeves 10 are arranged on the conveying member 110 at equal intervals and then conveyed to the posture adjustment assembly 130 for posture adjustment, and the posture adjustment among the star sleeves 10 can be performed without mutual interference, thereby ensuring the accuracy of posture adjustment.

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 implicitly indicating 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," "secured," and the like are to be construed broadly and can, 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 meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate 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 considered as "fixed transmission connection" with another element, the two elements may be fixed in a detachable connection manner or in an undetachable connection manner, and power transmission can be achieved, such as sleeving, clamping, integrally-formed fixing, welding and the like, which can be achieved in the prior art, and is not cumbersome. 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 show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
