Technical Field

[0001] The utility model relates to the field of workpiece production equipment, in particular to a holding device for flexible production and processing of workpieces. Background Art

[0002] The workpiece refers to the object being processed during the machining process. It can be a single part or a combination of several parts fixed together. There are various ways to process the workpiece, including turning, milling, planing, grinding, casting, forging, etc.

[0003] During the production and processing process, the workpiece needs to be clamped and positioned by a fixture. However, the fixture used for the workpiece in the existing technical solution is relatively simple in structure and cannot be used to clamp and position workpieces of different sizes. This leads to limitations in the actual application of the fixture. Utility Model Content

[0004] The embodiment of the present application solves the technical problem that the workpiece fixture in the existing technical solution is not suitable for clamping and positioning workpieces of different sizes due to its relatively simple structure, which leads to limitations in actual application of the fixture, by providing a holding device for flexible production and processing of workpieces.

[0005] The technical solutions adopted in the embodiments of this application are as follows:

[0006] A holding device for flexible production and processing of workpieces, comprising a base, a support block for supporting the workpiece, a clamping mechanism for clamping and fixing the workpiece, a driving device for driving the clamping mechanism to move, a limiting slide bar for limiting the movement of the clamping mechanism, a protrusion for supporting the clamping mechanism, and a limiting slide rail arranged on the base; the support block is arranged at the top center of the base; two groups of symmetrically placed driving devices are installed on the base; the driving ends of the two groups of driving devices are both transmission-connected with the clamping mechanism; the two groups of clamping mechanisms both slide on the limiting slide bar, and the limiting slide bar is arranged on the base; the bottom ends of the two groups of clamping mechanisms are both provided with the protrusion; the two groups of protrusions both slide on the limiting slide rail.

[0007] A further technical solution is: the clamping mechanism includes a movable plate, a slider sliding on the limiting slide rod, a baffle for abutting against the workpiece, and a buffer assembly for buffering the baffle; the movable plate is arranged on the slider; the slider is arranged on the driving end of the driving device; several groups of buffer assemblies arranged in a linear array are arranged on the movable plate; each group of buffer assemblies is connected to the baffle; the bottom end of the movable plate is provided with the protrusion.

[0008] A further technical solution is: the buffer assembly includes a spring for buffering the baffle and a telescopic rod for limiting the spring; the spring is arranged around the telescopic rod; the telescopic end of the telescopic rod is connected to the baffle, and the other end of the telescopic rod is connected to the movable plate; one end of the spring is connected to the baffle, and the other end of the spring is connected to the movable plate.

[0009] A further technical solution is: the clamping mechanism further includes a damping block; and the baffle is provided with a plurality of groups of the damping blocks arranged in a linear array.

[0010] A further technical solution is: the driving device is a cylinder.

[0011] A further technical solution is: a plurality of groups of feet arranged in a rectangular array are provided at the bottom of the base.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] 1. Due to the arrangement of the base, support block, clamping mechanism, drive device, limiting slide, protrusion and limiting slide rail, when the workpiece needs to be clamped and fixed, the workpiece is first placed on the top of the support block, and the center of the workpiece is aligned with the center of the support block. Then, the driving ends of the two drive devices are retracted at the same time. Since the driving ends of the two drive devices are respectively connected to the corresponding clamping mechanisms, when the driving ends of the two drive devices are retracted at the same time, the two clamping mechanisms can be driven to slide along the limiting slide rod at the same time. When the two clamping mechanisms move close to the workpiece and rest on both sides of the workpiece, the workpiece placed on the support block can be effectively fixed. When the two clamping mechanisms slide along the limiting slide rod, the protrusions at the bottom ends of the two clamping mechanisms will also slide along the limiting slide rail. At this time, the two protrusions can respectively support the corresponding clamping mechanisms, thereby making the two clamping mechanisms more stable during movement. Since the driving ends of the two sets of driving devices are extended and retracted at the same time, the two sets of clamping mechanisms can be driven to slide closer or away at the same time, so the distance between the two sets of clamping mechanisms can be adjusted, and then the two sets of clamping mechanisms can clamp and fix workpieces of different sizes, thereby greatly improving the practicality of the holding device.

[0014] 2. Due to the configuration of the movable plate, slider, baffle, and buffer assembly, when the two drive device drive ends are simultaneously extended and retracted, the two sets of sliders will simultaneously slide closer together or away from each other along the limit slide bars. Because the baffles are fixedly connected to the movable plate via several sets of buffer assemblies, and the movable plate is fixedly connected to the slider, when the two sets of sliders simultaneously slide closer together or away from each other along the limit slide bars, they can drive the two sets of baffles to slide closer together or away from each other simultaneously. When the two sets of baffles simultaneously abut against both sides of a workpiece, the workpiece simultaneously exerts a certain compressive force on both sets of baffles, causing the two sets of baffles to simultaneously compress the corresponding springs and telescopic rods. When the springs and telescopic rods are in a compressed state, the springs exert a certain reaction force on the baffles, causing the two sets of baffles to firmly abut against both sides of the workpiece, thereby firmly clamping the workpiece to the support block. When the baffles abut against the workpiece and the springs are in a compressed state, the springs provide a certain buffering effect, thereby providing a certain degree of protection for the workpiece. When the spring is in a compressed state, the telescopic rod can prevent the spring from deforming, thereby providing a certain degree of protection for the spring.

[0015] 3. Due to the setting of the damping block, when the baffle rests on the workpiece, the damping block on the baffle will contact the workpiece. At this time, the damping block will increase the friction between the baffle and the workpiece, thereby making the two sets of baffles more secure in fixing the workpiece.

[0016] 4. Due to the setting of the bottom foot, it is convenient for the staff to adjust the position of the clamping device. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The embodiment of the present application solves the technical problem that the workpiece fixture in the existing technical solution is not suitable for clamping and positioning workpieces of different sizes due to its relatively simple structure, which leads to limitations in actual application of the fixture, by providing a holding device for flexible production and processing of workpieces.

[0022] The technical solution in the embodiments of the present application is to solve the above problems, and the overall idea is as follows:

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] A holding device for flexible production and processing of workpieces, such as Figure 1 As shown, it includes a base 1, a support block 2 for supporting a workpiece, a clamping mechanism 3 for clamping and fixing the workpiece, a driving device 4 for driving the clamping mechanism 3 to move, a limiting slide 5 for limiting the movement of the clamping mechanism 3, a protrusion 6 for supporting the clamping mechanism 3, and a limiting slide rail 7 arranged on the base 1. The support block 2 is arranged at the top center of the base 1. Two groups of driving devices 4 are installed on the base 1, which are symmetrically placed. The driving ends of the two groups of driving devices 4 are both connected to the clamping mechanism 3 in a transmission manner. The two groups of clamping mechanisms 3 slide on the limiting slide 5, and the limiting slide 5 is arranged on the base 1. The bottom ends of the two groups of clamping mechanisms 3 are both provided with a protrusion 6. The two groups of protrusions 6 slide on the limiting slide rail 7.

[0025] The support block 2 is fixedly connected to the center of the top of the base 1. Two sets of symmetrically placed drive devices 4 are fixedly installed at the rear end of the top of the base 1. The drive devices 4 are preferably cylinders. The driving ends of the two sets of drive devices 4 are both connected to the clamping mechanisms 3. The two sets of clamping mechanisms 3 slide on the limiting slide 5, and the two sets of clamping mechanisms 3 are both sleeved on the limiting slide 5. The limiting slide 5 is fixedly connected to the top of the base 1. The bottom ends of the two sets of clamping mechanisms 3 are both fixedly connected to the protrusions 6. The limiting slide rail 7 is fixedly connected to the front end of the top of the base 1. The two sets of protrusions 6 slide on the limiting slide rail 7.

[0026] Due to the arrangement of the base 1, support block 2, clamping mechanism 3, drive device 4, limiting slide 5, protrusion 6 and limiting slide rail 7, when it is necessary to clamp and fix a workpiece, the workpiece is first placed on top of the support block 2, and the center of the workpiece is aligned with the center of the support block 2. Then, the driving ends of the two drive devices 4 are simultaneously retracted. Since the driving ends of the two drive devices 4 are respectively connected to the corresponding clamping mechanisms 3, when the driving ends of the two drive devices 4 are simultaneously retracted, the two clamping mechanisms 3 can be driven to slide along the limiting slide 5. When the two clamping mechanisms 3 move close to the workpiece and abut on both sides of the workpiece, the workpiece placed on the support block 2 can be effectively fixed. When the two clamping mechanisms 3 slide along the limiting slide 5, the protrusions 6 at the bottom ends of the two clamping mechanisms 3 will also slide along the limiting slide rail 7. At this time, the two protrusions 6 can respectively support the corresponding clamping mechanisms 3, thereby making the two clamping mechanisms 3 more stable during movement. Since the driving ends of the two sets of driving devices 4 are extended and retracted at the same time, the two sets of clamping mechanisms 3 can be driven to slide closer or away at the same time, so the distance between the two sets of clamping mechanisms 3 can be adjusted, and then the two sets of clamping mechanisms 3 can clamp and fix workpieces of different sizes, thereby greatly improving the practicality of the holding device.

[0027] like Figure 2 and Figure 3 As shown, the clamping mechanism 3 includes a movable plate 31, a slider 32 that slides on a limiting slide bar 5, a baffle 33 for abutting the workpiece, and a buffer assembly 34 for buffering the baffle 33. The movable plate 31 is mounted on the slider 32. The slider 32 is mounted on the driving end of the drive device 4. The movable plate 31 is provided with a plurality of groups of buffer assemblies 34 arranged in a linear array. Each group of buffer assemblies 34 is connected to the baffle 33. A bump 6 is provided at the bottom end of the movable plate 31.

[0028] The buffer assembly 34 includes a spring 341 for buffering the baffle 33 and a telescopic rod 342 for retaining the spring 341. The spring 341 is disposed around the telescopic rod 342. The telescopic end of the telescopic rod 342 is connected to the baffle 33, and the other end of the telescopic rod 342 is connected to the movable plate 31. One end of the spring 341 is connected to the baffle 33, and the other end of the spring 341 is connected to the movable plate 31.

[0029] The movable plate 31 is fixedly connected to the slider 32. The slider 32 is fixedly connected to the driving end of the drive device 4. Several groups of buffer assemblies 34 arranged in a linear array are fixedly connected to the movable plate 31. Each group of buffer assemblies 34 is fixedly connected to the baffle 33. A bump 6 is fixedly connected to the bottom end of the movable plate 31. The telescopic end of the telescopic rod 342 is fixedly connected to the baffle 33, and the other end of the telescopic rod 342 is fixedly connected to the movable plate 31. One end of the spring 341 is fixedly connected to the baffle 33, and the other end of the spring 341 is fixedly connected to the movable plate 31.

[0030] Due to the arrangement of the movable plate 31, the sliders 32, the baffles 33, and the buffering assembly 34, when the driving ends of the two sets of driving devices 4 are simultaneously extended and retracted, the two sets of sliders 32 will simultaneously slide closer together or away from each other along the limiting slide bar 5. Since the baffles 33 are fixedly connected to the movable plate 31 via the plurality of buffering assemblies 34, and the movable plate 31 is fixedly connected to the sliders 32, when the two sets of sliders 32 simultaneously slide closer together or away from each other along the limiting slide bar 5, they can drive the two sets of baffles 33 to simultaneously slide closer together or away from each other. When the two sets of baffles 33 simultaneously abut against both sides of the workpiece, the workpiece will simultaneously exert a certain extrusion force on the two sets of baffles 33, causing the two sets of baffles 33 to simultaneously compress the corresponding springs 341 and telescopic rods 342. When the springs 341 and telescopic rods 342 are in a compressed state, the springs 341 will exert a certain reaction force on the baffles 33, causing the two sets of baffles 33 to firmly abut against both sides of the workpiece, thereby firmly clamping the workpiece to the support block 2. When the baffles 33 abut against the workpiece and the springs 341 are in a compressed state, the springs 341 can provide a certain buffering effect, thereby providing a certain degree of protection for the workpiece. When the springs 341 are in a compressed state, the telescopic rods 342 can prevent the springs 341 from deforming, thereby providing a certain degree of protection for the springs 341.

[0031] like Figure 2 As shown, the clamping mechanism 3 further includes a damping block 35. The baffle 33 is provided with a plurality of groups of damping blocks 35 arranged in a linear array.

[0032] A plurality of groups of damping blocks 35 arranged in a linear array are fixedly connected to the baffle 33 .

[0033] Due to the setting of the damping block 35, when the baffle 33 rests on the workpiece, the damping block 35 on the baffle 33 will contact the workpiece. At this time, the damping block 35 will increase the friction between the baffle 33 and the workpiece, thereby making the two sets of baffles 33 more secure in fixing the workpiece.

[0034] like Figure 1 As shown, the bottom of the base 1 is provided with a plurality of groups of feet 11 arranged in a rectangular array.

[0035] Four groups of feet 11 arranged in a rectangular array are fixedly connected to the bottom of the base 1.

[0036] Due to the provision of the base 11 , it is convenient for workers to adjust the position of the clamping device.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0038] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
