Description

Technical Field

[0001] This utility model belongs to the field of tooling technology, specifically relating to a carriage assembly tooling. Background Technology

[0002] In the assembly production of the measuring machine carriage and Z-axis, the carriage needs to be positioned and clamped. The traditional operation mode relies on manual assembly on ordinary steel workbenches. Workers usually place the carriage directly on the table and assemble it by "visual alignment + manual pressing". When positioning, the mounting holes and connecting surfaces of the carriage are aligned by experience, without a dedicated positioning reference; when clamping, the carriage is manually held to prevent slippage; after assembly, it is manually moved to the next station; tools and parts such as wrenches and screws are placed randomly on the table or in the surrounding area.

[0003] Traditional operating methods have the following drawbacks: 1. Poor positioning accuracy and low product consistency: Due to the lack of dedicated positioning devices, the system relies entirely on worker experience, making it difficult to constrain the spatial posture of the carriages. This results in large fluctuations in the assembly quality of carriages in the same batch, which may even affect the assembly of downstream equipment. 2. Unstable clamping and low assembly efficiency. Due to the lack of automated / semi-automated clamping devices, it relies entirely on manual fixation, which cannot balance "clamping force" and "operational convenience". When manually holding it, uneven force can easily cause the carriage to shift, requiring repeated adjustments and long assembly time. 3. Inconvenient workpiece transfer and easy damage to products. Because ordinary workbenches do not have a moving function and do not integrate the "assembly + transfer" integrated design, they break the production process. When manually handled, they are prone to surface scratches and structural deformation due to bumps, which increases the rework rate. When transferring between multiple workstations, back-and-forth handling also wastes time. 4. Ergonomic defects and high worker fatigue: The table height and operating space were not designed for the operating posture of the carriage assembly, and the ergonomic requirements were ignored. The height of the ordinary workbench is fixed, and workers need to bend over and stand on tiptoe to operate. Long-term operation can easily cause lumbar and cervical strain.

[0004] In summary, there is an urgent need to provide a tooling for positioning and clamping the carriage during assembly with the Z-axis, thereby improving assembly accuracy and efficiency. Summary of the Invention

Detailed Implementation

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Reference Figures 1 to 9 In some embodiments of this utility model, a carriage assembly fixture is proposed, including a main frame 100 and a positioning and clamping assembly 200.

[0023] like Figure 1 As shown, the main frame 100 is constructed using metal profiles connected by welding and bolts to form a stable three-dimensional frame structure, such as a rectangular three-dimensional frame structure. This serves as the basic load-bearing and support component of the entire tooling, ensuring structural stability and preventing deformation during the assembly of the slide 1 and Z-axis 2, thus providing a fundamental guarantee for assembly accuracy. An upper operating platform 110 is installed on top of the main frame 100, and the upper operating platform 110 has a horizontal working surface 111.

[0024] The height and spatial layout of the main frame 100 can be ergonomically designed according to the operating posture design when the carriage 1 and Z-axis 2 are assembled, so as to avoid the operator bending over or tiptoeing to operate and alleviate work fatigue. The upper operating table 110 is made of metal plate with certain strength and flatness, and is fastened to the metal profile of the main frame 100 by bolts to form a horizontal working surface 111, which serves as the reference bearing surface when the carriage 1 and Z-axis 2 are assembled.

[0025] The bottom of the main frame 100 can be equipped with omnidirectional casters 120 and directional casters 130 with braking function, enabling the entire tooling to move flexibly and be easily transferred to different assembly stations and work areas, meeting the needs of production layout and work scheduling, avoiding the time-consuming and risky manual handling, and improving the efficiency of flow between multiple workstations. The omnidirectional casters 120 and directional casters 130 are made of materials suitable for industrial scenarios, with wear-resistant and shock-absorbing properties. The braking mechanism is operated by foot pedal or handle to lock and unlock the omnidirectional casters 120 and directional casters 130, preventing the tooling from moving during assembly and affecting assembly accuracy and work safety.

[0026] The positioning and clamping assembly 200 is used to position and clamp the slide 1. It is located on the main frame 100, specifically on the upper operating table 110, and above the upper operating table 110.

[0027] like Figure 2 As shown, the positioning and clamping assembly 200 includes a first clamping support column 210, a second clamping support column 220, a positioning assembly 230, a clamping assembly 240, and a support frame 250 connected between the first clamping support column 210 and the second clamping support column 220. The support frame 250 includes a support beam 251, on which a bottom positioning support component 252 is provided for supporting the slide 1 from the bottom. The first clamping support column 210 and the second clamping support column 220 are located at both ends of the support beam 251, and the bottom ends of the first clamping support column 210 and the second clamping support column 220 are fixed on the horizontal working surface 111. The positioning assembly 230 and the clamping assembly 240 are arranged laterally opposite to each other, corresponding to the first clamping support column 210 and the second clamping support column 220, respectively, for positioning and clamping the slide 1 from the opposite sides of the slide 1.

[0028] The positioning component 230, clamping component 240 and bottom positioning support component 252 on the support beam 251 work together to achieve reliable clamping and positioning of the slide 1, avoiding the slide 1 from shifting or shaking during assembly, thereby ensuring assembly accuracy and greatly improving the first-pass yield of the slide 1 and Z-axis 2 assembly and significantly improving assembly efficiency.

[0029] The first clamping support column 210 and the second clamping support column 220 are vertically installed on the horizontal working surface 111 of the upper operating platform 110. They are connected by bolts and adopt a metal square column structure to provide vertical support and installation foundation for the support beam 251, etc.

[0030] The support beam 251 is made of metal profiles or plates and is perpendicular to the first clamping support column 210 and the second clamping support column 220.

[0031] The bottom positioning support component 252 is screwed to the support beam 251. Multiple components are arranged along the extension direction of the support beam 251 to provide stable bottom support for the carriage 1. The bottom positioning support component 252 includes a first support plane 253 and a second support plane 254. The first support plane 253 and the second support plane 254 intersect at a non-acute angle, i.e., a right angle or an obtuse angle. The carriage 1 is supported on the bottom positioning support component 252 with its bottom length direction parallel to the support beam 251. One support plane of the bottom positioning support component 252 is in contact with the bottom surface of the carriage 1, and the other support plane is in contact with an adjacent side surface of the bottom surface of the carriage 1, achieving reliable support and limiting. The first support plane 253 and / or the second support plane 254 may be provided with features such as bosses and slots to adapt to the shape of the bottom or side surface of the carriage 1, forming a differentiated spatial support layout to meet diverse assembly requirements.

[0032] In some embodiments of this utility model, such as Figures 2 to 4 As shown, the support frame 250 also includes a first connecting vertical beam 255 and a second connecting vertical beam 256 arranged opposite to each other, through which the support beam 251 is connected to the first clamping support column 210 and the second clamping support column 220 respectively.

[0033] Specifically, the bottom end of the first connecting vertical beam 255 is fixed to one end of the supporting horizontal beam 251, the top end of the first connecting vertical beam 255 is connected to the top end of the first clamping supporting column 210, the bottom end of the second connecting vertical beam 256 is fixed to the other end of the supporting horizontal beam 251, and the top end of the second connecting vertical beam 256 is connected to the top end of the second clamping supporting column 220, so that the supporting frame 250 is in an approximately U-shaped frame.

[0034] The positioning component 230 is disposed on the first connecting vertical beam 255, specifically at the top end of the first connecting vertical beam 255; the clamping component 240 is disposed on the second connecting vertical beam 256, specifically at the top end of the second connecting vertical beam 256, thereby making the positioning component 230, the clamping component 240 and the bottom positioning support component 252 on the support beam 251 form a stable triangular support clamping structure, improving the positioning and clamping reliability of the slide 1.

[0035] The top end of the first connecting vertical beam 255 can be fixedly connected to the top end of the first clamping support column 210 by means of screw fastening or welding. Similarly, the top end of the second connecting vertical beam 256 can be fixedly connected to the top end of the second clamping support column 220.

[0036] To adjust the position of the support frame 250, thereby adjusting the assembly posture of the carriage 1 and the Z-axis 2 to facilitate the assembly of different parts of the carriage 1 with the Z-axis 2, in some embodiments of this utility model, the top end of the first connecting vertical beam 255 is rotatably connected to the top end of the first clamping support column 210, and the top end of the second connecting vertical beam 256 is rotatably connected to the top end of the second clamping support column 220, realizing the rotatable connection between the support frame 250 as a whole and the first clamping support column 210 and the second clamping support column 220; the second clamping support column 220 and the second connecting vertical beam 256... The support frame 250 is equipped with a locking assembly 270 that cooperates with each other to lock the support frame 250 in a vertical assembly position or a horizontal assembly position. When in the vertical assembly position, the first connecting vertical beam 255 and the second connecting vertical beam 256 are in a vertical state, and the support crossbeam 251 is kept in a horizontal state. When in the horizontal assembly position, the first connecting vertical beam 255 and the second connecting vertical beam 256 are in a horizontal state, and the support crossbeam 251 is kept in a horizontal state. At this time, the height of the support crossbeam 251 is higher than the height of the support crossbeam 251 when the support frame 250 is in the vertical assembly position.

[0037] The above structure allows the support frame 250 to be stabilized in a vertical or horizontal assembly position, thereby correspondingly stabilizing the carriage 1 and the Z-axis 2 in a vertical assembly state (e.g., Figure 8 (as shown) or horizontal assembly state (such as) Figure 9 As shown in the figure, this allows operators to assemble the carriage 1 and Z-axis 2 from different positions, avoiding the need for operators to bend over or stand on tiptoe, which helps reduce the difficulty of operation and further improves the convenience and efficiency of assembly.

[0038] An clearance section 140 is formed on the upper operating platform 110 to prevent the slide 1 and the Z-axis 2 from rotating with the support beam 251.

[0039] A buffer pad 112 is provided on the horizontal working surface 111 of the upper operating table 110 at the position corresponding to the slide 1 in the horizontal assembly state, so as to avoid collision damage to the slide 1.

[0040] For clamping assembly 240, such as Figures 2 to 5As shown, it includes a fixed sleeve 241, a vertical positioning base plate 242, and a clamping component 243. The fixed sleeve 241 is arranged parallel to the supporting beam 251 and fixed to the top of the second connecting vertical beam 256. The top of the second clamping support column 220 is rotatably connected to the fixed sleeve 241, thereby rotatably connecting the second connecting vertical beam 256 and the second clamping support column 220. The fixed sleeve 241 has through-holes at both ends and has internal threads, while the vertical positioning base plate 242 has an external threaded connection portion 24. 4. Its external threaded connection part 244 is threadedly connected to the inner end of the fixed sleeve 241 (with the end of the fixed sleeve 241 facing the slide 1 as the inner end and the end away from the slide 1 as the outer end). The clamping member 243 is a horizontal shaft with external threads. It is threadedly connected to the outer end of the fixed sleeve 241, screwed into the interior of the fixed sleeve 241 from the outer end of the fixed sleeve 241, and abuts against the external threaded connection part 244 of the vertical positioning base plate 242, and then abuts against the vertical positioning base plate 242.

[0041] After the slide 1 is hoisted and placed on the bottom positioning support component 252 on the support beam 251, one side of it cooperates with the positioning component 230 to achieve positioning. Then, the vertical positioning base plate 242 is rotated to press against the slide 1 on the opposite side of the slide 1, clamping and fixing the initially positioned slide 1. Then, the pressing component 243 is tightened to press against the vertical positioning base plate 242 to prevent the vertical positioning base plate 242 from retracting, so that the slide 1 remains stable during assembly, avoiding positional displacement due to external forces and ensuring assembly accuracy. After the assembly operation is completed, the pressing component 243 is reversed to release the slide 1, and it is hoisted and removed.

[0042] The first connecting vertical beam 255 and the first clamping support column 210 are rotatably connected via a horizontally arranged rotating shaft 260. The rotating shaft 260 is fixedly connected to the first clamping support column 210, and the first connecting vertical beam 255 is rotatably connected to the rotating shaft 260. Figures 2 to 4 As shown.

[0043] For locking component 270, such as Figure 2 As shown, the system includes a locking pin 271 on the first clamping support column 210 and a locking plate 272 on the first connecting vertical beam 255. The locking plate 272 rotates with the first connecting vertical beam 255. The locking plate 272 has two locking holes corresponding to the vertical assembly position and the horizontal assembly position, which can be referred to as the first locking hole 273 and the second locking hole 274, respectively. When the support frame 250 rotates to the vertical assembly position, the locking pin 271 engages with the first locking hole 273 to achieve locking. When the support frame 250 rotates to the horizontal assembly position, the locking pin 271 engages with the second locking hole 274 to achieve locking.

[0044] Specifically, the locking plate 272 is welded or screwed to the first connecting vertical beam 255, and can be located at the rotating shaft 260. The rotating shaft 260 passes sequentially through the first clamping support column 210, the locking plate 272, and the first connecting vertical beam 255. Both the locking plate 272 and the first connecting vertical beam 255 are rotatably engaged with the rotating shaft 260. A connecting block 275 is provided on one side of the first clamping support column 210, and a locking pin 271 is provided on the connecting block 275.

[0045] In some embodiments of this utility model, the positioning component 230 includes a fixed part 231 and a detachable part 232. The fixed part 231 is fixedly connected to the first connecting vertical beam 255 by means of screw connection or welding. The detachable part 232 is detachably connected to the fixed part 231 and protrudes relative to the fixed part 231 toward the side where the slide 1 is located.

[0046] Both the detachable part 232 and the fixed part 231 are metal block structures. The specific shape of the detachable part 232 can be designed according to the external features of the slide 1 and the assembly positioning requirements. It can be fixed to the fixed part 231 with bolts, and the positioning surface accuracy is ensured by machining. During positioning, the grooves of the corresponding parts of the detachable part 232 and the slide 1 contact and cooperate to achieve the initial accurate positioning of the slide 1 during assembly, determine the key position coordinates of the slide 1, and provide a basis for subsequent clamping and assembly.

[0047] Multiple detachable parts 232 can be designed according to the different shape characteristics and assembly positioning requirements of different carriages 1, and can be selected and used according to the different clamping and positioning requirements of different carriages 1, thereby improving versatility.

[0048] For the slide 1, which has a relatively large height in the Z-axis 2 axial direction, in order to further improve the positioning and clamping reliability of the slide 1, in some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 , Figures 6 to 9 As shown, a third connecting vertical beam 257 is connected to the second connecting vertical beam 256. The third connecting vertical beam 257 is equipped with a side auxiliary clamping assembly 280, used to assist in clamping the slide 1 from the side. When the support frame 250 is in the vertical assembly position, as shown... Figure 8 As shown, the side auxiliary clamping assembly 280 is located above the clamping assembly 240. When the support frame 250 is in the horizontal assembly position, as... Figure 9 As shown, the side auxiliary clamping assembly 280 is located to the left of the clamping assembly 240. With the combined action of the bottom positioning support component 252, the positioning assembly 230, the clamping assembly 240, and the side auxiliary clamping assembly 280, the relatively tall carriage 1 can be effectively restricted in its degree of freedom during assembly, and its spatial position can be precisely determined.

[0049] Of course, the third connecting vertical beam 257 can also be set on the first connecting vertical beam 255, and no specific restrictions are imposed here.

[0050] Furthermore, such as Figure 7 As shown, the side auxiliary clamping assembly 280 includes a fixed base 281, an auxiliary clamping component 282, a clamping reversing seat 283, a horizontal shaft 284, and a vertical shaft 285. The fixed base 281 is fixed on the third connecting vertical beam 257. The horizontal shaft 284 is fixedly connected to the fixed base 281. The clamping reversing seat 283 is rotatably connected to the horizontal shaft 284 and can move axially along the horizontal shaft 284. The vertical shaft 285 is fixedly connected to the clamping reversing seat 283. The auxiliary clamping component 282 is rotatably connected to the vertical shaft 285 and can move axially along the vertical shaft 285. The clamping reversing seat 283, together with the auxiliary clamping component 282 and the longitudinal axis 285, can rotate around the transverse axis 284 and can also move axially along the transverse axis 284. The auxiliary clamping component 282 can also rotate around the longitudinal axis 285 and can also move axially along the longitudinal axis 285, thereby realizing the lateral and longitudinal position movement of the auxiliary clamping component 282 and the adjustable pitch angle, so as to be suitable for the side clamping of various types of carriages 1.

[0051] Specifically, such as Figure 7 As shown, the fixed seat 281 is fastened to the third connecting vertical beam 257 with screws, clamping the reversing seat 283. The horizontal shaft 284 is inserted and fixed on the fixed seat 281. The clamping reversing seat 283 has a transverse through hole and a transversely extending through notch connected to the transverse through hole. The clamping reversing seat 283 is inserted into the horizontal shaft 284 through its transverse through hole, and then the position is fixed by tightening the transversely extending through notch with bolts. If rotation or movement is required, the bolts can be loosened for adjustment, and the bolts can be tightened again after adjustment.

[0052] The longitudinal shaft 285 is fixedly connected to the auxiliary clamping component 282. Meanwhile, the clamping reversing seat 283 has a longitudinal through hole and a longitudinally extending through notch connected to the longitudinal through hole. The auxiliary clamping component 282 is inserted into the longitudinal through hole of the clamping reversing seat 283 through the longitudinal shaft 285. Then, the position is fixed by tightening the longitudinally extending through notch with bolts. If rotation or movement is required, the bolts can be loosened for adjustment. After adjustment, the bolts are tightened again.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
