[0030] The beneficial effects of the present utility model are as follows:

[0031] The present utility model provides a clamping device. When the two jaw assemblies need to be spaced apart by a certain distance, the driving mechanism outputs a movement in the third direction, that is, Figure 1 the movement in the Z direction in the figure. The driving mechanism drives the first slider to move upward. Since the first bearing is slidably engaged with the first slider, when the first bearing slides, it can drive the first plate to rotate around the pivot shaft of the transmission member, and then drive the second plate to rotate. Since the second bearing is slidably engaged with the second slider, it can further push the second slider to move in the second direction. As a result, the second slider is pushed to move in the second direction between the two jaw assemblies, overcoming the elastic force of the first reset member, separating the two jaw assemblies, and parts such as steel shells that need to be clamped can be placed between the two jaw assemblies. When the output end of the driving mechanism moves in the opposite direction, the first slider descends, forcing the first bearing to slide back in the first slider, and causing the entire transmission member to reverse. The second slider moves away from the jaw assembly, and the two jaw assemblies approach each other under the action of the first reset member, completing the clamping action of parts such as steel shells. During the clamping process, different from the structure of the common jaw cylinder, this clamping device does not need to design an air circuit, and realizes the approach and separation of the two jaw assemblies through the cam transmission method, saving the setting of the air circuit and making the structure more reliable.

[0032] The present utility model also provides a steel shell feeding device.

The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is at a lower horizontal height than the second feature.

[0051] In the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "left", and "right" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0052] This embodiment provides a clamping device, such as Figures 1-3As shown, the clamping device includes a support assembly 10, a clamping mechanism 20, a transmission mechanism 40 and a driving mechanism 30. The clamping mechanism 20 includes a first reset member 21 and two clamping jaw assemblies 22. The two clamping jaw assemblies 22 are arranged relatively to each other in a first direction (X direction in the figure) and are respectively slidably matched with the support assembly 10 in the first direction. The first reset member 21 is elastically connected between the two clamping jaw assemblies 22; the transmission mechanism 40 includes a first slider 41, a transmission member 42 and a second slider 43. The transmission member 42 includes a first plate 421 and a second plate 422 that are connected and arranged at an angle. The transmission member 42 is pivotally connected to the support assembly 10 in the middle. The first slider 41 is located on the side of the second slider 43 away from the clamping mechanism 20. In the second direction (Y direction in the figure, Y direction In the first direction (the direction perpendicular to the X direction), the free end of the first plate 421 slides with the first slider 41 through the first bearing 423, and in the third direction (the Z direction in the figure, the Z direction is respectively perpendicular to the X direction and the Y direction), the free end of the second plate 422 slides with the second slider 43 through the second bearing 424, and the second slider 43 slides with the support assembly 10 in the second direction, and the first direction, the second direction and the third direction are perpendicular to each other; the first slider 41 is connected to the output end of the driving mechanism 30, and the driving mechanism 30 can drive the first slider 41 to move along the third direction, so that the first plate 421 rotates and drives the second plate 422 to drive the second slider 43 along the second direction to enter between the two clamping jaw assemblies 22 to separate the two clamping jaw assemblies 22.

[0053] In the clamping device, when the two clamping jaw assemblies 22 need to be spaced a certain distance apart, the driving mechanism 30 outputs movement along the third direction, that is, Figure 1In the movement in the Z direction, the driving mechanism 30 drives the first slider 41 to move upward. Since the first bearing 423 is slidably engaged with the first slider 41, the first bearing 423 can drive the first plate 421 to rotate around the pivot shaft of the transmission member 42 while sliding, and then drive the second plate 422 to rotate. Since the second bearing 424 is slidably engaged with the second slider 43, the second slider 43 can be pushed to move in the second direction, and then the second slider 43 is pushed to move in the second direction between the two jaw assemblies 22, overcoming the elastic force of the first reset member 21 to separate the two jaw assemblies 22. Parts to be clamped such as the steel shell 200 can be placed between the two jaw assemblies 22. When the output end of the driving mechanism 30 moves in the opposite direction, the first slider 41 descends, forcing the first bearing 423 to slide back in the first slider 41 and causing the entire transmission member 42 to reverse. The second slider 43 moves away from the jaw assemblies 22, and the two jaw assemblies 22 approach each other under the action of the first reset member 21 to complete the clamping action of parts such as the steel shell 200. During the clamping process, different from the structure of common jaw cylinders, this clamping device does not need to design an air circuit, and realizes the approach and separation of the two jaw assemblies 22 through the cam drive method, saving the setting of the air circuit and making the structure more reliable.

[0054] Optionally, as Figure 2 shown, the first slider 41 is provided with a first chute 411 along the second direction, and the first bearing 423 can slide in the first chute 411; the second slider 43 is provided with a second chute 432 along the third direction, and the second bearing 424 can slide in the second chute 432. Through the above settings, the sliding fit between the first bearing 423 and the first slider 41, and the sliding fit between the second bearing 424 and the second slider 43 are realized.

[0055] In other embodiments, a slide rail can also be provided on the first slider 41, and a slider can be installed on the first bearing 423, which is not limited herein.

[0056] Optionally, as Figure 2 shown, the length of the first plate 421 is less than the length of the second plate 422. Through the above settings, since the rotation centers of the second plate 422 and the first plate 421 are the same and rotate by the same angle, the free end of the second plate 422 will move a greater distance. Thus, only a small upward distance of the first slider 41 is required, and the second slider 43 can slide a large distance in the second direction, so that the stroke of the driving mechanism 30 does not need to be set too large, thereby saving energy.

[0057] Optionally, as Figure 2 and Figure 3As shown in the figure, a top block 431 is installed at one end of the second slider 43 close to the clamping mechanism 20, and one end of the top block 431 facing the clamping mechanism 20 is conical. Through the above settings, the top block 431 can enter between the two jaw components 22 in an inclined posture, with less resistance.

[0058] Optionally, there are at least two top blocks 431, and there are also at least two pairs of jaw components 22, which can simultaneously clamp at least two steel shells 200.

[0059] It should be noted that the connecting parts 32 between the second slider 43 and the top block 431 in the figure will not be elaborated here, and they all belong to the second slider 43.

[0060] Optionally, as Figure 1 and Figure 3 shown, in order to increase the return speed of the second slider 43, a second reset member 44 is provided between the second slider 43 and the support assembly 10, which can provide a pulling force for the return of the second slider 43. Among them, the first reset member 21 and the second reset member 44 are both springs.

[0061] Optionally, as Figure 2 and Figure 3 shown, a third bearing 222 is provided at one end of each jaw component 22 close to the top block 431, and the side surface of the top block 431 is in rolling fit with the third bearing 222. Through the above settings, when the top block 431 separates the two jaw components 22, it abuts against the circumferential surface of the third bearing 222 to form a rolling fit, preventing excessive friction from damaging the jaw components 22.

[0062] Furthermore, as Figure 3 shown, the jaw component 22 includes a jaw 221 and the above-mentioned third bearing 222. The first reset member 21 is respectively connected to the two jaws 221. A clamping groove adapted to the outer shape of the steel shell 200 (or the part to be clamped) is provided at one end of each jaw 221, and the third bearing 222 is rotatably provided at the other end of the jaw 221.

[0063] Optionally, as Figure 1 shown, the driving mechanism 30 includes a first push rod 31 and a connecting part 32. The first push rod 31 can output motion along the third direction; the connecting part 32 is connected to the output end of the first push rod 31, and the first plate 421 is connected to the connecting part 32. Among them, the first push rod 31 is a pneumatic driving part in the production line. One air source is uniformly used in one production line, which saves costs. For each workstation, compared with using a jaw cylinder, the air circuit is also more concise.

[0064] In an alternative embodiment, as Figure 1As shown, the support assembly 10 includes a fixing member 11 and a movable member 12. The transmission mechanism 40 is installed on the fixing member 11. The movable member 12 can rotate or move relative to the fixing member 11. The clamping mechanism 20 is arranged on the movable member 12 to switch between a clamping position facing the transmission mechanism 40 and a position avoiding the transmission mechanism 40. Through the above arrangement, the clamping mechanism 20 can be brought to the next working station by the movable member 12, and parts such as the steel shell 200 can be clamped for the next operation.

[0065] Of course, in other embodiments, the support assembly 10 can be an integral frame, and does not necessarily have the function of transferring the position of the clamping mechanism 20. It only needs to ensure that the clamping mechanism 20 has the functions of clamping and releasing, which is not limited herein.

[0066] This embodiment also provides a steel shell feeding device, as Figure 4 and Figure 5 shown. The steel shell feeding device includes a feeding mechanism 50, a transfer mechanism 60, a dust removal mechanism 70, and the above-mentioned clamping device. The feeding mechanism 50 can transport the steel shell 200 to the feeding position 51; the dust removal mechanism 70 is located downstream of the feeding position 51 and is provided with a dust removal position. The transfer mechanism 60 is configured to transfer the steel shell 200 at the feeding position 51 to the dust removal position. The dust removal mechanism 70 is configured to blow air to remove dust from the steel shell 200 at the dust removal position; the transfer mechanism 60 can also transfer the steel shell 200 at the dust removal position between the two jaw assemblies 22. Through the above arrangement, the feeding, dust removal, and discharging of the steel shell 200 can be realized. The air circuit provided by the driving mechanism 30 is simple, and the cleanliness of the steel shell 200 can be improved.

[0067] Optionally, as Figure 5 shown, the dust removal mechanism 70 includes a dust removal frame body 71, a dust removal pipe 72, and a jig 73. A dust removal hole 711 is opened at the top of the dust removal frame body 71; the dust removal pipe 72 is installed on the dust removal frame body 71. One end of the dust removal pipe 72 is communicated with an external air source, and the other end faces the dust removal hole 711; the jig 73 is arranged at the top of the dust removal frame body 71. The jig 73 is provided with a limit groove 731 having the same shape as the outer shape of the steel shell 200, and the dust removal hole 711 is located at the bottom of the limit groove 731. Through the above arrangement, the transfer mechanism 60 places the steel shell 200 at the limit groove 731, and the limit groove 731 is the dust removal position, and the dust removal pipe 72 blows air to clean the steel shell 200.

[0068] Optionally, as Figure 5As shown, the dust removal mechanism 70 further includes an induction member 74. The induction member 74 is installed on the dust removal frame 71 and is configured to sense the presence or absence of the steel shell 200 in the limit slot 731, and is communicatively connected to the driving mechanism 30. Through the above arrangement, the induction member 74 can sense the arrival of the steel shell 200 at any time, so that the driving mechanism 30 drives the clamping mechanism 20 to loosen, waiting for the transfer mechanism 60 to place the steel shell 200 into the clamping mechanism 20 for the next operation. Optionally, the induction member 74 is a photoelectric inductor. In other embodiments, the induction member 74 can also be a distance inductor, etc., which is not limited herein.

[0069] Optionally, two steel shells 200 reach their respective loading positions 51 simultaneously. There are two dust removal positions and two clamping mechanisms 20. That is to say, the steel shell loading device synchronously realizes the loading, dust removal and unloading of two steel shells 200. In other embodiments, the number of synchronous steel shells 200 can also be three, four or more, which is not limited herein.

[0070] Optionally, as Figure 4 and Figure 6 shown, the transfer mechanism 60 includes a clamping component 67 and a transfer driving component (not labeled) that drives the clamping component 67 to move. The clamping component 67 includes four clamping members 672 and a connecting plate 671. The connecting plate 671 is connected to the output end of the driving component. The four clamping members 672 are all connected to the connecting plate 671 and are arranged in a matrix. Two of the clamping members 672 correspond to two loading positions 51, and the other two clamping members 672 correspond to two dust removal positions. Moreover, the distance between the loading position 51 and the dust removal position and the distance between the dust removal position and the clamping mechanism 20 are equal. Thus, when two clamping members 672 in one row clamp two steel shells 200 at the loading position 51, the other two clamping members 672 in the other row clamp two steel shells 200 at the dust removal position. When the driving component drives the connecting plate 671 to move, the transfer of two rows of steel shells 200 from the loading position 51 to the dust removal position and from the dust removal position to the clamping mechanism 20 is realized simultaneously.

[0071] In other embodiments, the driving component can be a combination of two direction modules or a manipulator, which will not be elaborated herein. The above methods all use motor drive, resulting in relatively high costs.

[0072] To solve the above problems, in this embodiment, as Figure 4 and Figure 6As shown in the figure, the driving component includes a second push rod 61, a rotating member 62, a first gear 63, a second gear 64, a track plate 65 and a cam component 66. The second push rod 61 can be pneumatically driven and can output linear motion. The output end of the second push rod 61 is pivotally connected to one end of the rotating member 62. The rotating member 62 is fixedly connected to the first gear 63. The second gear 64 meshes with the first gear 63. The track groove 651 is in an inverted U shape. The cam component 66 includes a cam plate 661 and a cam 662. A long circular hole 6611 is formed in the cam plate 661. The cam 662 can slide in the long circular hole 6611. One end of the cam plate 661 is coaxially arranged with the second gear 64. The cam 662 is connected to the connecting plate 671. When the output end of the second push rod 61 expands and contracts, due to the arrangement of the rotating member 62, the first gear 63 can be driven to rotate, and then the second gear 64 is driven to rotate, and then the cam 662 is driven to rotate. Due to the limitation of the track groove 651, when the cam 662 rotates, the cam 662 changes along the track of the track groove 651, driving the connecting plate 671 to complete ascending translation and descending. In the above arrangement, instead of using a motor or a manipulator for driving, the cam component 66 and the gears are used for ingenious transmission, reducing the cost. At the same time, the second push rod 61 and the first push rod 31 share the air source, streamlining the air circuit arrangement in a production line and saving costs.

[0073] Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
